Where Is Rogaine Effective at Growing Hair?

Rogaine, or minoxidil, is clinically proven to regrow hair on balding spots on the head; however, the effects are limited and temporary. When people take minoxidil orally for blood pressure, it sometimes causes hair growth in other areas, such as the cheeks and forehead, the American Hair Loss Association reports.

Rogaine was the first drug approved by the Food and Drug Administration to treat male pattern baldness, states the American Hair Loss Association. It is only effective on the crown of the head for men. Rogaine is actually more effective at treating hereditary hair loss in women.

Finasteride is another FDA-approved drug for hair loss, states the American Hair Loss Association. It is more effective at treating male pattern baldness than Rogaine because it inhibits a protein that makes dihydrotestosterone, the hormone that shrinks hair follicles, leading to baldness.
