Propecia is a medication used in hair loss treatment. In about 80% of patients it stops further hair loss and stimulates regrowth. Propecia prevents the conversion of testosterone to dihydrotestosterone (DHT) in the body. DHT is involved in the development of benign prostatic hyperplasia (BPH) and hair loss.
