Finasteride

Propecia is a drug used to treat hair loss in men. It is an oral medication, taken once a day, and available on prescription. It is prescribed to stimulate hair growth in men with male pattern baldness.

Propecia’s active ingredient is finasteride, and it was originally developed to treat a condition which causes enlarged prostate glands (benign prostatic hyperplasia).

Finasteride works by reducing dihydrotestosterone (DHT) levels in the scalp. The hormone DHT contributes to male pattern baldness, and Propecia medication helps to reverse the hair loss process by decreasing the effect of DHT on the hair follicles.

It takes around three months to see any results from using Propecia. It is recommended for men over the age of 18 only and must not be taken by women.

Millions of patients take Propecia with no side effects, or minimal and reversible side effects.
