Finasteride or minoxidil for hair loss?

They work differently and are often used together. Finasteride reduces conversion of testosterone to DHT, addressing the hormonal driver of pattern hair loss. Minoxidil is a vasodilator applied topically or, off-label, taken at low oral doses. Finasteride carries considerations around fertility and mood; oral minoxidil requires blood-pressure monitoring. Benefit from either is maintained only while treatment continues.
