Best Hair Loss Device For Quicker Results
Theradome PRO Laser Hair Growth Helmet LH80
ProsDoesn’t require daily treatmentsConsCan overstimulate follicles if used too often
While this device doesn’t claim to help regrow hair overnight, it does promise results quicker than others on the market. Using laser technology, this helmet improves hair density and volume and stimulates hair growth in as little as one month. Plus, while most devices recommend daily treatments, Theradome recommends 20-minute sessions twice weekly. “I also like the Theradome PRO LH80. It is easy to use and makes for a painless at-home treatment,” says Dr. Lal.
Red light wavelength: 680nm
Best used: Two times a week
Amazon rating: 4.1/5 stars
An Amazon reviewer says: “This product saved my long, pretty hair. I’d lost so much hair from the stress of learning I had a brain tumor and then from general anesthesia from the necessary cranial surgery. Ultimately, I had bald patches on the sides of my hair and thinning around the incision and top of my head. For over a year nothing helped and my hair loss worsened. BUT! Within 3 months of using Theradome, I saw baby hairs return. After a year of use my hair is back to 80% with new hair coming in daily. I will never be without my Theradome!”

Best Universal Hair Loss Tool
HigherDose Red Light Hat
ProsAdjustable strapComfortable to useConsTakes months to see results
Here’s another option for an unassuming yet efficacious red light hat. This one requires only 10 minutes a day to address hair loss in both men and women, and it promises to deliver new growth by months five or six. You may see a little more hair loss than usual when you start using the cap, but don’t worry—the brand says that’s perfectly normal, and it just means that weaker strands are stepping aside so stronger ones can move in.
Red light wavelength: 650nm
Best used: Once a day
HigherDose rating: 4/5 stars
A HigherDose reviewer says: “Before using, I would have handfuls of hair come out in the shower, but I see so much less shedding. I see less white scalp than before, and I see new growth!”

Best Comb for Hair Loss
HairMax Ultima 9 Classic LaserComb
ProsCordlessPortableConsNot hands-free
Equipped with nine medical-grade lasers, this HairMax comb aims light at the follicle to strengthen weak strands and increase density. The device may not be hands-free, but it is portable and allows you to control which areas get treated. Quick tip: If your laser cap doesn’t cover your whole scalp, try using this comb for the rest of your head.
Red light wavelength: 680nm
Best used: Three times a week
Amazon rating: 3.9/5 stars
An Amazon reviewer says: “I have been using HairMax Ultima 9 for three months. I have just started feeling thicker hair on the roots when I run through the hair. I use it as instructed, every other day, and run through the scalp five to six times on clean hair. I’m waiting for the hair fall to stop soon. The peach fuzz definitely satisfies me. (I was diagnosed with AGA and lost around 60 percent of the volume.)”

Meet the Experts
HEARST
Dr. Robert Finney is a board-certified cosmetic dermatologist and hair loss expert based in New York City.
Dr. Karan Lal is double-board certified pediatric and cosmetic dermatologist based in Scotssdale, Arizona.
What are the leading causes of thinning hair and hair loss?
HEARST
“By far and away, the leading cause of hair loss in both men and women is androgenetic alopecia. Almost all men and around 50 percent of women in their lifetime will suffer from genetic hair loss,” says Dr. Finney. While genetics are the main factors that lead to hair loss, stress can also be a factor, adds Dr. Lal. “Telogen effluvium is a post-stress form of hair loss,” says Dr. Lal.

Why are hair loss devices becoming so popular?
HEARST
“The hair market has grown substantially in the past few years. For many people, their hair is an identifier. Hair loss is a very emotional condition in my clinic, with many of my patients having depression and anxiety related to their hair loss,” says Dr. Lal.
The pandemic also increased the need for more support for patients suffering from stress-induced hair loss. “There is a type of temporary hair loss called telogen effluvium. In this condition, a lot of the hairs all over the scalp go into the resting phase all at once–this is seen clinically as an abrupt, significant increase in shedding. COVID was a cause of this, so during the pandemic, many people were noticeably concerned when they saw a lot of hair fall. This has likely driven a lot of focus on the cause and treatments of hair loss,” adds Dr. Finney.
How does light therapy combat or reverse hair loss?
HEARST
“Low-level laser light therapy in the red light range triggers a reaction in the cells that help regenerate the hair to do several things: improve the blood supply of nutrients, improve the health of the cells that help regenerate the hair, and help reduce the local effects of hormones on the hair follicle. All of this helps to regrow new hairs and reverse the miniaturization of damaged hairs,” says Dr. Finney.
“There are many different types of light therapy for hair loss, especially red light and blue light. Red light reduces inflammation and increases energy in our skin and hair cells. Blue light, on the other hand, is said to induce low-level hair growth through a different mechanism. In a recent study, blue light increased hair density and shaft diameter by 90% after ten weeks of use. Similar findings have been reported with red light helmets as well,” says Dr. Lal.

Are hair loss devices safe?
If the thought of putting a high-tech helmet on top of your head makes you nervous, you don’t need to worry. “It doesn’t get any safer. For one thing, it is just light, which is natural. It doesn’t penetrate deep into the skin. We have plenty of studies to support the use of red light to help with inflammation and signs of aging, so there is that added benefit compared to some of our topical options that can create inflammation. I will often recommend these devices in conjunction with a topical routine. Not only do we have studies to support synergy between the two, but if you were to get any irritation from a topical, the red light could help ameliorate it!” says Dr. Finney.
However, it is important to know that there can be some mild side effects, depending on the tool you use. “Blue light devices can darken your hair or scalp because blue light does affect pigment-making cells, so just be mindful of that,” says Dr. Lal. Each device comes with a certain set of instructions, so it’s important to read the manual carefully and follow the manufacturer’s recommendation.
How should you use hair loss devices in your routine?
If you already use hair loss serums or supplements, there’s no need to put them aside once you begin using a hair growth device. “For genetic hair loss, the combination approach always yields the best results. We have plenty of clinical trials that show this. It is important for patients with genetic hair loss to realize that there is no cure; it is a progressive condition. So, pick a treatment routine that you are okay with the side effects and one that is sustainable in the long run for you and your lifestyle. So, I always lay out the different options, discuss their efficacies and drawbacks, and then come up with a plan specific to each patient. It is important to reinforce that with hair loss, results are slow. Take good photos before starting a treatment routine and set a reminder to check back in on it in 4-6 months. Results take time,” says Dr. Finney.
