It is mostly seen in young and middle-aged males, with increasing incidence with age, and the incidence is higher in European and American populations than in Asian populations. The hairline is receding and M-shaped, often accompanied by dandruff and an itchy feeling. Hair thinning, the rate and extent of hair loss varies from person to person, most of them progress slowly, and our study found that the pathogenesis is mainly related to androgenic and genetic factors.

Alopecia areata: also known as “ghost shaving”. The cause is unknown, but may be related to immunity and genetics. Patients often have a sudden appearance of round or oval-shaped hair loss patches on the head, which are non-scarring.
