Can women take finasteride?

Yes, some women can and maybe should take finasteride if they have Polycyctic Ovarian Syndrome and hair loss or Frontal Fibrosing Alopecia (an autoimmune disease which causes hair loss in women). It should NOT be taken by women who have hair loss and might get pregnant as it can cause fetal hermaphrodites which is a high risk for women taking finasteride when getting pregnant.  See article here:  https://www.mdlinx.com/journal-summaries/finasteride-hair-loss-hirsutism-dermatologic-alopecia/2019/02/06/7556054/?spec=dermatology
