An FDA-approved medication called finasteride is used to treat male pattern hair loss, androgenic alopecia, and benign prostate hyperplasia.

- Androgenic alopecia (gradual thinning or loss of hair on the scalp in men)
- Benign prostatic hyperplasia (symptoms of an enlarged prostate without prostate cancer)
How does it work?

Finasteride works by blocking an enzyme that turns testosterone into DHT. This helps reduce the size of the prostate, which makes it easier to pee. It also slows down hair loss in men. Dihydrotestosterone (DHT) is a hormone that makes the prostate gland grow larger than usual, leading to hair loss on the scalp.
Dosage?
- 1 mg oral tablets (Propecia)
- 5 mg oral tablets (Proscar)
Finasteride should be stored at room temperature, away from moisture.
Common Side Effects:
