A variety of genetic and environmental factors likely play a role in causing androgenic alopecia. Although researchers are studying the factors that may contribute to this condition, most of these remain unknown. Researchers have determined that this form of hair loss is related to hormones called androgens, particularly an androgen called dihydrotestosterone (DHT).
Androgens are important for normal male sexual development before birth and during puberty. Androgens also have other important functions in both males and females, such as regulating hair growth and sex drive.
Male pattern baldness is caused by a genetic sensitivity of hair follicles to DHT, which causes them to shrink when exposed to it. This shortens their lifespan and prevents them from producing hair normally.
