Androgenetic alopecia is an extremely common disorder that affects roughly 50% of men and perhaps as many women above the age of 40 years. Reportedly, as many as 13% of
premenopausal women experience androgenetic alopecia. However, the incidence of androgenetic alopecia increases greatly in women following menopause, and, according to a source, it may affect 75% of women older than 65 years.
A community-based study of androgenetic alopecia in six Chinese cities indicated that the prevalence of androgenetic alopecia in both Chinese males and females was lower than that seen in Caucasians, but of comparable incidence to their Korean counterparts.
