Incidence of Female Androgenetic Alopecia (Female Pattern Alopecia)

The incidence of female androgenetic alopecia, also known as female pattern alopecia, was studied in 1006 Caucasian women aged 20 and above. The study found that female pattern alopecia is quite common, beginning in the late 20s and reaching almost 30% in women over 30 years of age. The study also noted that many women had early type II male androgenetic alopecia, which was not necessarily associated with high levels of testosterone. The study supports the notion that female pattern alopecia is a separate entity from male androgenetic alopecia and is not androgen dependent.
