In men, finasteride (originally marketed as Proscar) is approved for hair loss associated with androgens. In one study, 62% of women also taking oral contraceptives containing the synthetic progestin drospirenone reported improvement. So it may be effective for female hair loss in the setting of increased androgen. But studies are limited and it is harmful to the male fetus so should not be used by women thinking about becoming pregnant or who are pregnant.
