👉 Propecia, sold under the brand name Finasteride, is a pharmaceutical medication primarily used to treat male pattern baldness (male alopecia) and other forms of hair loss. It is a topical solution containing the active ingredient finasteride, which works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), a hormone that contributes to hair follicle shrinkage and hair loss. By reducing DHT levels, Propecia helps preserve existing hair follicles and can potentially stimulate new hair growth, leading to a reduction in hair loss and an increase in hair density over time. It is typically applied twice daily to the affected areas of the scalp, and its effectiveness varies among individuals.
