Androgenic alopecia (AGA) is a common form of hair loss in women caused by genetics and the hormone DHT. DHT miniaturizes hair follicles over time, making the scalp appear thinner. Oral contraceptives can help lower testosterone levels but are not adequate treatment on their own. Blocking DHT with medications like spironolactone or finasteride are more effective treatments. Minoxidil is the only FDA-approved treatment for female hair loss, but it requires twice daily application and hair may regrow if use is discontinued.
