Finasteride is a medication that is primarily used to treat hair loss in men, particularly those experiencing male pattern baldness, known scientifically as androgenetic alopecia. This condition affects millions of men worldwide, leading to significant psychological distress. Finasteride works by inhibiting the enzyme 5-alpha-reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT). High levels of DHT are linked to hair follicle shrinkage and hair loss.
