Loss of hair, which is an extension of the skin, may cause aesthetic problems. Alopecia areata, which can be seen in both genders, can cause hair loss in an area with a 2-3 cm radius as well as loss of the hair of the entire body. Since its cause is related to a problem in the immune system, treatment methods targeting the immune system are quite successful.

The most common type of hair loss is related to a hormone and can be seen in both men and women. Successful treatment methods are: specific shampoos and lotions, vitamin and mineral supplements, an anti-hormone medication used for men, and vitamin injections into the scalp.
