Are you worried about thinning hair? It’s not just about looks—thinning hair not only alters your external appearance, but I’ve seen firsthand how it can profoundly influence your self-esteem and confidence levels. While genetics may play a significant role, other contributing factors, such as hormone levels, stress, diet, and the presence of underlying medical issues, can also exacerbate the problem.
According to Dr. Aneesha Dhargalkar, MD, “As with any medical condition, multiple variables can lead to hair loss, and these variables are often individualized to each person. It is indeed a combination of internal factors such as hormone levels and genetics as well as external factors including stress levels and diet that lead to the condition of hair loss.”
After testing numerous shampoos for hair loss, we narrowed the list to the top nine. We assessed their performance and overall user satisfaction, providing reliable insights to help you make the most informed decision possible.

What you should know
The Tea Tree Scalp Care Regeniplox expertly leverages the strength of five active ingredients to improve the look of thinning hair while preserving your hair’s natural protective oils.
The shampoo’s active ingredients, tea tree oil, clover flower, Kakadu plum, pea peptides, turmeric, and ginseng, have been shown to decrease hair shedding.
Priced at $1.76 per fluid ounce, or $30 total, this shampoo offers everything you need to gently cleanse and condition your locks for a fuller, healthier look.
This shampoo is best for anyone experiencing thinning hair who wants a gentle way to clean their hair without harsh chemicals that strip away the hair’s natural oils.
Pros
Packaging is made from recycled materials
Increases hair volume and strength
Cons
Some may be sensitive to tea tree oil
Should be used with accompanying conditioner and tonic for best results
Why we like Tea Tree Scalp Regeniplox as the best strengthening
Tea Tree Scalp Care Regeniplox Shampoo is our top strengthening shampoo for its exceptional botanical blend of ingredients that effectively cleanse and nourish the hair and scalp while minimizing breakage and shedding.
Reducing shedding is a key factor in addressing hair loss and promoting healthier, fuller-looking hair. By incorporating treatments that effectively reduce fallout, you can support hair growth and maintain the integrity of your hair.
”A certain amount of hair shedding is part of the hair growth cycle. In fact, it is normal to lose around 50-100 hairs a day. However, when we exceed this amount, we start developing hair loss. In addition, when we lose excess hair, we are more likely to have increased difficulty growing it back.” per Dr. Dhargalkar.
Its gentle yet powerful formula offers a unique lemon basil and fir scent to your strands while working to maintain a healthy scalp environment—essential for promoting strong and resilient hair growth. The botanical ingredients work harmoniously to cleanse the hair and scalp without causing dryness or irritation, making it suitable for various hair types and conditions. (

)
When the 18 participants in a clinical trial consistently used the Tea Tree Scalp Care Regeniplox shampoo, conditioner, and tonic for eight weeks, an impressive 85% reported experiencing increased hair volume and strength. (
7
) This notable percentage of people who notice fuller-looking hair showcases the products’ efficacy in boosting overall hair health and strength.
Tea tree oil is known for its potential to promote hair growth and has many other therapeutic properties. It contains anti-inflammatory and antimicrobial agents, making it a natural choice for many dermatologic conditions. In a double-blind, randomized study, tea tree oil was added to a mixture of FDA-approved topical medications for hair loss in those with alopecia. Over the 32-week study, participants found that the tea tree oil blend showed a quicker response time and better results than the minoxidil treatment alone. (

)
These results suggest that combining tea tree oil with minoxidil in a microemulsion formulation could be a promising approach for enhancing hair growth and managing conditions associated with hair loss. (

)
It takes only a few minutes to incorporate this product into your hair care routine. Simply lather and rinse your hair like your normal shampoo. Additionally, you can set this product up for auto-shipment through Amazon so that you never run out.
What customers are saying
With a notable 3,800 reviews on Amazon and an impressive overall rating of 4.4 stars, this product has garnered significant user praise. Customers particularly appreciate the delightful scent and the visible results they have experienced after incorporating this product into their daily hair care routine.
“I am a 65-year-old female with extremely thin hair. I lose so much hair daily that I now have a balding spot on the back of my head. I ordered this shampoo and have been using it for about a month. I noticed a great improvement in my hair. Not only does my hair appear thicker, but I am losing only about a third of the amount of hair I had previously. I would highly recommend this shampoo!”
“Cigg1027,” Verified Amazon purchaser
Yet, not everyone has experienced the same results. In their review, Wendy Zuern, a verified purchaser on Amazon, shared, “I’ve used this for a month or so now and haven’t noticed any difference—I still have just as much hair in the drain as usual. Smells nice, though.”

Nioxin Scalp + Hair Thickening System offers a three-piece solution that includes a shampoo, conditioner, and leave-in hair treatment that leaves your hair and scalp hydrated and healthy.
This system works in tandem to provide thinning hair the moisture and protection it needs against hair breakage while still managing to remove excessive oils and build-up from the scalp.
For less than $30, you could have an entire hair care system dedicated to the delicate needs of your thinning hair.
The Nioxin Scalp + Hair Thickening System is best suited for anyone looking to improve the health and appearance of their natural or damaged hair experiencing light to progressive hair thinning.
This product is available in four distinct formulations, so no matter your hair type you can have salon-quality hair care products delivered directly to your door.
Pros
All products are easy to use
Available in four different formulations
Some formulations are safe for color-treated hair
Increases fullness and decreases breakage
Cons
Must be purchased as a set
Requires multiple products for best results
Why we like Nioxin Scalp + Hair Thickening System as the best shampoo and conditioner
To our experts, the Nioxin Scalp + Hair Thickening System measures up as the best shampoo and conditioner for hair loss due to its exceptional features and benefits tailored to address the specific needs of thinning hair.
This system offers personalized solutions for individuals experiencing various levels of hair thinning, effectively catering to various hair types, from natural to damaged.
With four distinct systems, or formulations to choose from, Nioxin ensures that each person can find a tailored solution that meets their specific needs, ultimately promoting hair that appears healthier and fuller.
System 1 targets natural or untreated hair—those that haven’t undergone chemical processing, such as straighteners or relaxers—and is specifically designed for lightly thinning hair.
System 2 also focuses on untreated hair and effectively combats progressively thinning hair.
System 3 and 4 were designed to work well on colored, dried, or damaged hair. System 3 is formuatled for thinning hair, while system 4 addresses progressively thinning hair, which is more advanced than System 3.
Each kit in the Nioxin system includes a shampoo, conditioner, and leave-in moisturizing hair serum:
Step one in each kit is the scalp and hair shampoo, which replaces your normal shampoo. It’s rinsed out like normal.
Step two is the scalp and hair conditioner, which takes the place of your usual wash-out conditioner.
Step three is a leave-in scalp care and hair thickening treatment that should not be rinsed from the hair.
The Nioxin system’s individualized approach empowers users to select a formula that best aligns with their unique requirements, offering them the freedom to choose the most suitable product.
One of the key active ingredients in this system is caffeine. Research has shown that shampoos containing caffeine effectively reduce hair loss and enhance hair density. (
9
)
Caffeine has been found to stimulate cell metabolism and proliferation, potentially leading to stronger and thicker hair growth, making it a compelling choice for those seeking to improve the appearance of their hair. (
9
)
Moreover, the Nioxin Scalp + Hair Thickening System’s consistent recognition with the “Behind the Chair Stylist Choice Award: Favorite Thinning Haircare” for 16 consecutive years underscores its effectiveness and popularity among hair care professionals.
Users can feel assured that they are choosing a reliable and acclaimed product that consistently delivers results and garners a reputation for quality salon products at home.
What customers are saying
The Nioxin Scalp + Hair Thickening System has garnered over 3,600 reviews across various platforms, such as Amazon, where it maintains an impressive overall 4.4-star rating. Customers express satisfaction with the value they receive from using these products.
They particularly appreciate the pleasant scent and the noticeable improvement in the look and feel of their hair after incorporating the system into their regular hair care routine.
Chris M., a verified Amazon purchaser, shared their review, “There is definitely visible new growth. My ponytail is now much thicker!”
Contrastingly, Jonatan Tobon, a verified Amazon purchaser, does not feel the same. “I switched to this shampoo because a friend of mine recommended it to me, and she said it was the best thing in the universe… Now it’s not only my tips/ends, but half my hair is dried out.”

What you should know
Nutrafol Root Purifier Shampoo actively enriches hair health and balances the scalp microbiome with its antioxidant-rich Australian Wild Berries, vegan proteins, and prebiotics. These ingredients work together to combat dryness in the scalp and maintain optimal hair pH levels.
This shampoo excludes several harmful substances, such as parabens, sulfates, and synthetic fragrances, making it a safe and effective option for those seeking to improve hair health naturally.
Priced at $5.40 per ounce, or $44 altogether, this product has clinically proven results in rapidly improving dry and flaky scalps.
Nutrafol Root Purifier Shampoo is ideal for individuals with dry and itchy scalp because it’s sulfate-free, deeply cleansed without stripping the scalp of essential oils, and effectively removes excess oil while hydrating the hair and scalp.
The formula actively targets the root cause of unhealthy and damaged hair by creating an environment where the scalp can thrive, thanks to the blend of its nourishing ingredients.
Pros
Clinically proven results
Cons
Requires consistent use for best results
Some may be sensitive to the ingredients used
Not an all-natural product
Why we like Nutrafol Root Purifier Shampoo as the best for dry scalp and hair loss
As our expert pick for the best hair loss shampoo for those with a dry scalp, Nutrafol Root Purifier Shampoo goes beyond traditional cleansing by targeting the health of the hair and scalp microbiome.
This product is easy to use and is gentle enough for everyday use. Simply apply a small amount of product to your hair and massage into the scalp. It offers a unique scent with hints of citrus, such as grapefruit, balanced out by floral and woody undertones. Just rinse and repeat as you would your normal shampoo.
The scalp microbiome refers to the diverse microbial community that naturally exists on our scalp and hair. Maintaining a balanced microbiome is crucial for promoting healthy hair growth and preventing unwanted issues like hair loss. (
10
)
“The scalp surface is part of human skin and, as such, it serves as the body’s first line of defense against inflammation, infection, and other disorders,” according to Dr. Dhargalkar. “It does this by serving as host to a myriad of microorganisms, including bacteria and fungi. Therefore, a healthy scalp microbiome is essential to help ward off unwanted conditions such as seborrheic dermatitis, dandruff, and hair loss.”
Nutrafol Root Purifier Shampoo is formulated to support this delicate balance, promoting a healthy environment for hair to thrive. The scalp microbiome maintains the skin’s barrier function, protects the scalp against harmful pathogens, and supports the hair follicles’ overall health when balanced. “Maintaining a healthy scalp microbiome can protect against dandruff, eczema, and dermatitis,” adds Dr. Fatema Dawoodbhoy, MBBS, an academic doctor working in London.
Disruptions to the scalp microbiome can lead to scalp conditions like dandruff, seborrheic dermatitis, and even hair loss. Therefore, maintaining a healthy and balanced scalp microbiome is key to ensuring healthy hair growth and scalp wellness. (
11
)
Additionally, this shampoo is free of harmful substances such as parabens, sulfates, and synthetic fragrances, making it a safe and effective choice for those looking to enhance their hair’s health naturally.
In a clinical study involving 37 participants, this shampoo showcased remarkable results, with all users experiencing a significant reduction in sebum and improvement in dry, flaky scalps immediately following its use. This underscores the efficacy and rapid impact on scalp and hair health. (
12
)
Nutrafol Root Purifier Shampoo was developed by medical professionals. It was based on scientific knowledge and clinical insights to ensure that it targets the specific needs of individuals suffering from dry scalp and hair loss. With clinical results like these and a formulation that prioritizes scalp and hair health, users can rest assured that it delivers effective results.
While Nutrafol Root Purifier Shampoo offers numerous benefits for scalp health, one potential drawback could be that it may not be suitable for individuals with specific scalp conditions, like dandruff or seborrheic dermatitis, that may require medicated shampoos containing ingredients like ketoconazole or salicylic acid. (
13
)
Moreover, some users may find the price point of Nutrafol Root Purifier Shampoo, at $5.40 per ounce, of $44 in total, to be higher than that of other standard shampoos.
However, if you have any questions or concerns regarding the product, you can easily chat with Nutrafol through its website available Monday through Friday from 9 am to 9 pm EST. You can also conveniently reach representatives by phone or email.
What customers are saying
Based on over 2,000 Amazon reviews, the majority of customers have shared positive feedback, with only 10% of reviews rating it below 3 stars.
“I give a thumbs up for this shampoo. I am absolutely pleased with how my scalp feels. Hair shed was at a minimum. The results are my hair is not weighed down, my scalp feels clean, and my hair is soft.”
”Nicki74,” Amazon reviewer
However, it’s important to note that individual experiences may vary, as highlighted by some reviews that fell below three stars, indicating potential areas for improvement in the product’s performance.
Elaine O. mentioned, “I’ve only used this shampoo a few times, so it might be too soon to tell, but it doesn’t seem to work well on fine hair. It leaves hair feeling coated like it hasn’t fully rinsed out of your hair. And I thought the scent was nasty.”

The Izumi Tonic Shampoo strengthens and repairs damaged hair by infusing Japanese rice water rich in amino acids, vitamins, and antioxidants to restore hair health and reduce breakage.
The Izumi Tonic Shampoo offers significant benefits for hair health, including strengthening and repairing damaged hair, increasing hair diameter, and reducing split ends.
At $5.50 per ounce, this product offers exceptional value for those seeking to revitalize damaged hair.
The Izumi Tonic Shampoo is a powerful solution for those looking to strengthen and repair their sleek strands, particularly if you’re dealing with damage and breakage.
Its deep cleansing action removes impurities without stripping essential moisture, promoting healthier, smoother hair with visible results in strength and shine.
Pros
Specialized formulation for damaged hair
Clinically proven results
Cons

Higher initial price of $55 compared to standard shampoos
Why we like Izumi Tonic Strengthening Shampoo as the best for hair breakage and loss
We like shu uemura Izumi Tonic Strengthening & Thickening Rice Water Shampoo for its ability to significantly improve the appearance of brittle, damaged hair.
When paired with the mask and serum from the same line, this dynamic trio has shown impressive clinical results in strengthening hair by up to 30 times and decreasing the appearance of split ends by a notable 91%. (
14
)
This shampoo addresses and minimizes split ends so you can promote and maintain healthier, stronger hair over time, resulting in less hair loss and breakage.
Participants in the study also noticed a tangible increase in hair diameter after using these products. Rice water, renowned for its abundance of vitamins, amino acids, and minerals, works to fortify the hair shaft and enhance hair thickness. (
14
)
Reducing split ends can minimize further damage by strengthening the hair shaft and preventing it from breaking, since split ends leave the hair more vulnerable to damage and breakage. (
15
) “Overall, it can promote hair thickness but will not speed up hair growth,” adds Dr. Dawoodbhoy.
When the hair and scalp are adequately hydrated, it helps to maintain the natural moisture balance necessary for strong and resilient hair follicles. This hydration supports the hair growth cycle, promoting the development of stronger, healthier strands. (
16
)
This shampoo is easily incorporated into any hair care routine. It’s gentle enough for daily use—just wet the hair as you normally would, apply a small amount to the hair, massage gently onto the scalp and rinse.
Inspired by the ancient Japanese beauty ritual of yu-su-ru, in which hair is immersed in rice water for its beautifying properties, the Izumi Tonic Strengthening & Thickening Rice Water Shampoo rejuvenates strands, prevents breakage, and unveils smoother, more vibrant hair.
Additionally, the rice water utilized in this product is meticulously selected from Hyogo, Japan, showcasing a commitment to hair care traditions. Its subtle citrus scent combines beautifully with its fresh woody fragrance, leaving your hair reminiscent of a picturesque rice field.
Hydration aids in reducing hair breakage and fallout by helping to maintain the hair’s elasticity and strength. Moisturized hair is less prone to brittleness and damage, reducing breakage and shedding. This hydration also nourishes the scalp, promoting healthy hair growth and minimizing hair loss. (
15
)
The Izumi Tonic Strengthening & Thickening Shampoo fosters hydration by delicately cleansing the hair and scalp while preserving moisture levels, thereby preventing excessive dryness that could lead to breakage.
It’s safe to use on any hair type, aiming to add volume, minimize damage, reduce split ends, and ultimately decrease breakage and noticeable thinning. For optimal results, pair it with the complete izumi tonic haircare system, which includes the strengthening conditioner, strengthening hair mask, strengthening energizing spray, and thickening serum.
What customers are saying
While this product has received only 31 ratings on Amazon, the vast majority of reviews are overwhelmingly positive. Impressively, 86% of reviewers who shared feedback awarded it a 4-star rating or higher.
Users collectively appreciate its positive impact on the look and feel of their fine hair.
“I am very impressed with how clean my hair gets, and my scalp seems to be in much better shape than other products… My hair also feels cleaner, longer and softer over all.”

At $4.94 per ounce or $42 overall, this product offers salon-quality results and exceptional value for those looking to combat thinning hair and restore its vitality.
This shampoo is perfectly suited for anyone with fine or noticeably thinning hair that needs a little extra care and attention to improve the hair’s look and feel.

Increases hair volume and texture

Cons

Higher initial price of $42 compared to standard shampoos
Why we like KERASTASE Densifique Densité Shampoo as the best for thinning hair and loss
We recommend KERASTASE Densifique Densité Shampoo for thinning hair and loss due to its specialized formulation, which adds volume and enhances the appearance of fine, thinning hair.
Thinning hair can result from various factors, including hormonal changes during pregnancy or menopause and medical conditions like thyroid disorders and autoimmune diseases. (
17
)
Elevated cortisol levels, a natural hormone that regulates metabolism, inflammation, and stress, can further complicate hair health. When cortisol levels rise, they can weaken immune function, negatively impact mood, and may even contribute to hair loss. (
18
)
Lowering cortisol
can significantly benefit those experiencing hair thinning since high levels disrupt the hair growth cycle and lead to increased shedding. Chronic stress and elevated cortisol also cause inflammation, which can damage hair follicles and hinder new growth. (
19
)
This shampoo helps to counteract the effects of stress that may be caused by high cortisol levels, which can disrupt the hair growth cycle and result in increased shedding or hair loss. It does so by promoting a healthy environment, nourishing hair follicles, and taming any irritation to the scalp.
With a pleasant floral scent, KERASTASE Densifique Densité Shampoo features hyaluronic acid and peptides formulated to combat the effects of hair loss and reduce build up.
Hyaluronic acid attracts and retains moisture, improving scalp health and creating a favorable environment for hair growth. Its anti-inflammatory properties can also soothe the scalp and reduce follicle damage, ultimately supporting healthier hair. (
20
)
Peptides are composed of amino acids, the building blocks of proteins like collagen, elastin and keratin. Hair is made of 95% keratin proteins. These proteins also contribute greatly to the formulation of KERASTASE Densifique Densité Shampoo, providing multiple benefits essential for improving the health and appearance of thinning hair.
When incorporated into hair care products, peptides work to reinforce the hair fibers. This strengthening effect is crucial for individuals with thinning hair, as it helps prevent damage and promotes healthy hair growth. (
21
) “They also promote blood flow to the scalp, increasing the sizes of hair follicles allowing hair to thicken,” notes Dr. Dawoodbhoy.
This shampoo is meant to be used as a replacement for your normal shampoo and is suitable for daily use. But, for best results, it should be used as part of a complete set, which includes a thickening conditioner, thickening hair mousse, and leave-in hair serum.
What customers are saying
Reviews on third-party sites like Amazon are overwhelmingly positive. Approximately 88% of over 6,000 reviewers give it a 4-star rating or higher, while only 6% leave a 2-star rating or lower.
The vast majority of users appreciate how this product leaves their fine hair looking and feeling great.
Aileen E. Fernandez gives it a 5-star rating and says, ”My hair feels super clean and full after using it. I will keep repurchasing. I love all Kerastase products.”
However, not everyone considers it a good value for the money. Jane, another verified Amazon purchaser, gives it a 2-star rating: “Glad to hear it worked so well for others, but it does not work for me. My hair does not seem thicker. It now tends to fly away, is drier, and doesn’t hold its shape. Plus, it needs washing more often and is not as shiny. Back to my tried and true.”

The SUPERZERO Thinning Hair Shampoo Bar for Hair Growth is a shampoo bar that helps minimize hair breakage and improve shine.
The SUPERZERO Thinning Hair Shampoo Bar combines caffeine, menthol, and rosemary oil to stimulate the scalp’s circulation and improve blood flow to the hair follicle.
The unique solid shampoo bar formula replaces 16.8 oz worth of liquid shampoo in one easy-to-manage 2.15 oz bar.
This shampoo bar is great for anyone who wants to improve hair health while minimizing plastic consumption in a travel-friendly format.
This product offers a plastic-free alternative to typical liquid shampoos in plastic bottles.
Pros
Convenient, travel-friendly packaging
100% plastic and microplastic free
Cons
May take some getting used to if you’ve never tried a shampoo bar before
The bar should be dried between uses to prevent decomposition
May not lather as much as other shampoos
Why we like SUPERZERO Thinning Hair Shampoo Bar for Hair Growth as the best shampoo bar
SUPERZERO’s Thinning Hair Shampoo Bar for Hair Growth is our best shampoo bar for combating hair loss because of its scientifically proven compounds that promote hair growth and health. Moreover, the shampoo bar offers a two-in-one scalp treatment and cleansing formula.
While it may look like an ordinary bar of soap, it’s anything but. Think of it as a shampoo plus scalp treatment that nourishes your scalp as it gently cleanses your hair. It stimulates the scalp and supports a healthy microbiome, all while restoring smoothness and combating frizz.
Although shampoo bars vary widely in their efficacy, SUPERZERO leverages clinically proven ingredients to strengthen hair and enhance shine. One study found that rosemary oil performed as effectively as 2% minoxidil ointment for treating alopecia. (
22
)
Participants also reported greater adherence to the rosemary oil treatment regimen compared to minoxidil, highlighting its efficacy and ease of use over prescription treatment options for hair growth.
This shampoo bar serves as a powerful alternative to traditional liquid shampoos. Unliked liquid shampoos that use watered down ingredients, this shampoo bar offers a concentrated formula that the brand claims is five times more potent than liquid shampoos yet is gentle enough to use every time you wash your hair.
We appreciate its fragrance-, plastic-, sulfate-, and paraben-free formulation. The absence of harsh chemicals helps maintain your scalp’s natural balance and reduces the risk of irritation.
It’s also worth noting that this product can help cut down on microplastics compared to traditional shampoo bottles. These plastics can accumulate in our oceans and waterways, threatening marine life and ecosystems. Fish and other organisms can eat them as they break down, potentially affecting human health. (
23
)
Microplastics can absorb harmful chemicals and toxins from the environment, which may be released into the body upon ingestion. Studies suggest that microplastics can trigger inflammatory responses in the body, potentially leading to chronic health conditions. (
23
)
If you’re new to shampoo bars, it may take some time to adjust to them. Unlike standard liquid shampoos, shampoo bars require you to rub the bar between your hands to activate it before applying the shampoo bar to your wet hair and scalp.
It may not feel like it lathers fully at first, which may create a bit of a learning curve as you figure out how to wash your hair thoroughly. However, I personally prefer them for their convenience and natural ingredients.
Solid shampoo bars offer a cleaner, more eco-conscious hair care alternative and are extremely easy to travel with. They’re less likely to spill in transit and often take less water to rinse clean.
The SUPERZERO Thinning Hair Shampoo Bar for Hair Growth has created an eco-friendly formulation that strengthens hair and supports a healthier planet. Transitioning to a shampoo bar may improve your hair’s health, eliminating harmful chemicals and reducing your environmental footprint.
What customers are saying
Reviews on third-party sites highlight the excellent value for money this product provides. On Amazon, 137 ratings have been submitted, with over 60% of users giving it a 5-star review. Many users note that it lathers just as effectively as other shampoo brands they’ve tried.
“I used it for the second time last week and still don’t need to wash my hair yet. The scent is very herbal, and the small bar lathers well. There is no wasting lotion dripping out of your hand.”
Ilma Tikkanen, Verified Amazon purchaser
However, not everyone has had the same experience with this shampoo bar. Marion R. points out in her 1-star Amazon review, “I was very disappointed after the first shampoo. A lot was gone, and I have very fine, thinning hair. It will not last very long and also did not lather well. I would not recommend it.”

Why we like Mielle Organics Rosemary Mint Strengthening Shampoo as the best budget
Mielle Organics Rosemary Mint Strengthening Shampoo is our pick for best budget shampoo. Its remarkable ability to deliver results comparable to many pricier products in strengthening hair and reducing shedding makes it a great choice.
Despite being the least expensive shampoo on our list, Mielle doesn’t compromise on effectiveness. This formulation is infused with biotin, a vital nutrient that significantly boosts hair strength and promotes healthier growth while leaving strands with a refreshing mint scent. (

Additionally, the inclusion of coconut oil enhances this shampoo’s performance by locking in moisture. This is crucial for preventing dryness and brittleness, which can lead to breakage.
Coconut oil is one of the few oils that can penetrate the hair shaft effectively. This allows it to reduce protein loss during washing and styling. This shampoo helps reinforce hair strength by maintaining protein levels, making it less prone to damage and breakage. (

Beyond its impressive ingredients, Mielle’s Rosemary Mint Strengthening Shampoo also comes in a generously sized bottle, ensuring you always have your favorite hair care product on hand.
The larger size means that you won’t need to repurchase as frequently, allowing you to enjoy the shampoo’s benefits over an extended period without the hassle of constant restocking. This may be particularly advantageous for those who wash their hair daily.
Its formulation works well for all hair types, but is specifically formulated to promote and maintain the health of natural hair with curl types 3A to 4C, making it a versatile choice for those seeking to enhance their hair health without overspending. Many users have reported a significant reduction in noticeable shedding, further confirming its effectiveness.
To incorporate this shampoo into your hair care routine, simply apply a dime-sized amount of product to your hand and massage it onto wet hair to create a thick lather. Rinse thoroughly, repeat as needed, and follow with the Rosemary Mint Strengthening Hair Mask for best results.
What customers are saying
Mielle Organics Rosemary Mint Strengthening Shampoo has received over 21,000 ratings on sites like Amazon, earning an impressive overall rating of 4.5 stars. Approximately 75% of users give it a glowing 5-star review and recommend it to others.
“Loving this shampoo after about three months of use. The growth that I have experienced is amazing. I was noticing my hair thinning on top ever so slightly and feeling dry and damaged. However, after using this shampoo combined with the conditioner, leave-in, and hair oil, my hair is healthy and FULL. The thin spot has completely filled in, and the barber has been shocked at how quickly it happened. This stuff is the truth and a great bang for your buck. Hair is soft, tangle-free, and shiny all day.”

Some users, however, have reported experiencing waxy film after using the product.
Verified Amazon purchaser, Aimee shared, “I don’t know why this product has good ratings. This shampoo smells really good and has a nice lather but leaves my hair with a waxy buildup. It looks greasy immediately after washing and is weighted down.”

How to choose the best shampoo for hair loss
When selecting the best shampoo for your hair loss, certified dermatologist Dr. Shamsa Kanwal says, “It’s important to consider the underlying cause of the hair loss and select ingredients that target those specific concerns.”
This is because different types of hair loss may require specific ingredients or formulations to address the underlying issue causing the hair loss.
For instance, if your hair loss is due to hereditary factors like pattern hair loss, you may benefit from a shampoo that contains ingredients known to promote hair growth and strengthen the hair follicles. Patterned hair loss, also known as androgenetic alopecia, is a common condition that causes gradual hair thinning and loss in a specific pattern. (
25
)
Both men and women inherit genes that cause hair follicles to shrink and eventually stop growing hair, leading to patterned hair loss. Men often develop a receding hairline or bald patch, while women may notice gradual hair thinning over time.
While both genders can be equally affected by patterned hair loss, Dr. Kanwal tells us when it comes to treatment options, “men might benefit more from DHT-blocking ingredients like Capixyl and saw palmetto, while women might find better results with ingredients like Anagain, which focuses on prolonging the hair growth phase.”
However, if brittle or weak strands are causing your hair loss, prioritize using a moisturizing and strengthening shampoo to help prevent further damage and promote healthier hair growth. This formulation of shampoo will nourish and strengthen the hair, improve its resilience, and combat shedding.
How do hair loss shampoos work?
Hair loss shampoos work by cleansing the scalp and removing dirt and oil to create a healthy environment for hair growth. They often contain gentle ingredients that focus on cleansing the hair without stripping away its natural oils.
However, they may also contain specific ingredients that target hair loss issues, such as promoting hair growth and reducing shedding.
You may need to experiment with different formulations to determine which is most effective for your hair and scalp—so don’t be afraid to try a few and see which one works best for you.
Ingredients to look for and avoid
When browsing for a shampoo, it’s advisable to steer clear of ingredients such as bleaching agents, surfactants, and formaldehyde-releasing chemicals. These elements may strip the hair of its natural protective barrier, increasing the likelihood of breakage. (
26
)
Dr. Kanwal also recommends seeking shampoos containing beneficial ingredients like “biotin, caffeine, saw palmetto, and minoxidil.” These ingredients can contribute to a healthier scalp and promote the overall well-being of your hair.
FAQs
Do hair loss shampoos really work?
Hair loss shampoos have been shown to be effective in promoting hair growth and addressing hair loss concerns in many individuals. However, not every hair loss shampoo will work the same for everyone. (
27
)
Consistent and regular use of hair loss shampoos is often necessary to see significant results. However, it’s essential to recognize that not all products will yield the same outcomes for everyone.
If you have tried multiple hair loss shampoos over the past few weeks or months and have not observed any improvement, consulting a dermatologist or hair care specialist may be beneficial. They will be able to help you find a product that will work for you and identify the root cause of your hair loss.
What shampoo do dermatologists recommend for hair loss?
The American Academy of Dermatology Association offers recommendations for anyone concerned about hair loss.
They suggest opting for a gentle shampoo that preserves moisture in fragile and thinning hair. Following each shampoo, applying a moisturizing conditioner to coat the hair strands is equally important, reducing the potential for breakage and split ends.
Additionally, to help hair dry more quickly and minimize the need for excessive heat products, it’s recommended that hair be wrapped in a microfiber towel instead of blow-dried. (
28
)
Dr. Kanwal adds that when selecting a shampoo for healthier hair growth, it’s crucial to be mindful of your chosen ingredients. She advises avoiding “harsh sulfates and irritating chemicals,” as these components can harm the hair follicles and cause additional hair loss.
What is the difference between OTC and prescription hair loss shampoo?
The main difference between over-the-counter (OTC) and prescription hair loss shampoos lies in their active ingredients and how they function to address hair loss.
Most OTC shampoos contain milder active ingredients and aim to improve hair health and appearance. Their main focus is to nourish the scalp and hair follicles, helping with issues like hair thinning and breakage.
On the other hand, a prescription-strength shampoo requires a prescription from your dermatologist or healthcare provider. The ingredients in these shampoos are more potent and work at a deeper level to prevent hair loss and even promote hair growth. (
