“Underlying nutritional deficiencies and certain genetic predispositions may also contribute to the development of tinea nodosa,” says Dr. Mitchell. According to the NLM, these include anemia (iron deficiency), hypothyroidism (meaning the body doesn’t produce enough thyroid hormone on its own), and trichodystrophy (a genetic disorder that causes brittle hair and skin problems). Included.
However, styling that uses intense heat or harsh chemicals on the scalp and hair, such as using a curling iron or curling iron, frequent perms, chemical straightening, or relaxing treatments, can damage the hair follicles. This can cause damage and, in the worst case, permanent hair loss.
What you’ll probably notice
Tinea nodularis usually involves a combination of hair loss and changes in texture. The hair may become frayed, have small bead-like knots along the strands, and feel brittle to the touch. ” says Dr. Mitchell. “In more severe cases, hair thinning may occur in areas or there may be a general decrease in hair density.”

5. Severe dandruff
Besides dandruff, there is a more severe form of seborrheic dermatitis. It is a troublesome skin disease characterized by a rash (which may appear darker, paler, or redder than the surrounding skin) and scattered itchy, flaky patches. There are many oil glands, including the scalp. “This is caused by an inflammatory response to the microorganisms that live on our scalp, particularly Malassezia yeast colonies,” says Dr. Lo Cicco.
These flaky spots can combine with oil produced by the scalp and clog the hair follicles, ultimately impairing the hair’s nutritional supply and weakening its structure (not to mention Constant head scratching can lead to subsequent damage and hair loss). .12 Meanwhile, the inflammatory response can disrupt the normal hair growth cycle and cause telogen effluvium, Dr. Mitchell explains. Again, the hair follicles are attacked for a long period of time and then fall out in large quantities.
What you’ll probably notice
Apart from inflammation throughout the scalp, this type of hair loss usually does not involve dramatic hair loss, but rather a gradual loss of hair density, with seborrheic dermatitis being the most problematic. Hair loss increases in this area. “The hair itself can also become thinner and more fragile because the inflammatory process disrupts the growth cycle,” says Dr. Mitchell.

6. Inflamed hair follicles
Folliculitis is a skin disease that occurs when the hair follicle becomes inflamed and loses its integrity due to physical stimulation (shaving, traction, wigs) or infection (bacteria, fungi).13
There are two main types: superficial folliculitis and deep folliculitis. The former affects only part of the hair follicle and will probably heal within a few days, while the latter consumes the entire hair follicle and tends to be more severe and long-lasting.
“When a hair follicle becomes inflamed, it can cause damage to the surrounding tissue and disrupt the normal hair growth cycle,” Dr. Mitchell says. “In severe cases, the infection can lead to scarring and permanent hair loss.”
What you’ll probably notice
The type of folliculitis that occurs depends on the underlying cause (friction or infection), but “it usually appears as small acne-like bumps or pustules surrounding the affected hair follicle.” Dr. Mitchell says. “These may be itchy, tender, or painful, and in some cases may form lumps that resemble a rash.” As the condition progresses, the surrounding skin becomes inflamed and darkens or becomes lighter. You may start to notice redness or redness.
