Finasteride reduces dihydrotestosterone, increases testosterone, and may treat hirsutism in women.
research 5‐alpha‐reductase inhibitor treatment for frontal fibrosing alopecia: an evidence‐based treatment update
5-alpha-reductase inhibitors may help stabilize or slow down hair loss in some frontal fibrosing alopecia patients, but more research is needed to confirm their effectiveness and safety.
