Finasteride is a drug to treat benign prostate enlargement ( benign prostate hyperplasia / BPH). This drug can also be used to treat male pattern baldness caused by excess androgen hormones ( androgenetic alopecia ).

Finasteride works by inhibiting the production of the hormone dihydrotestosterone. This hormone is one of the causes of prostate gland enlargement and hair loss in men.

By inhibiting the production of the hormone dihydrosterone, finasteride can reduce the size of an enlarged prostate gland so that people with BPH can urinate more easily. While in baldness, finasteride can increase hair growth on the part of the head that has experienced baldness.
