TLDR Female and male AGA are different diseases.

This study presents arguments that female androgenetic alopecia (AGA) and male AGA are actually two different entities. It cites four facts about the diseases, including the fact that males with the genetic predisposition for male pattern baldness given large doses of testosterone rapidly develop typical male pattern baldness, while normal males can develop typical female AGA, as well as evidence from a family pedigree filled with female AGA, and a case report of a woman with female AGA and no circulating androgens. The study ultimately concludes that these are two entirely different diseases.
