Incidence of Female Androgenetic Alopecia (Female Pattern Alopecia)

BACKGROUND: Female pattern alopecia seems to be increasing. A recent article suggests that female androgenetic alopecia may not be androgen dependent and is a different entity than male androgenetic alopecia. OBJECTIVE: To determine the incidence at different ages of female androgenetic alopecia in 1000 Caucasian women 20 years of age and older. METHODS: A total of 1006 Caucasian women were examined for the presence of female androgenetic alopecia. CONCLUSION: Female androgenetic alopecia is quite common beginning in the late 20s and reaching its peak after 50 years of age.
