What is Rogaine?
Rogaine® (minoxidil) is a medicated lotion used to treat baldness or hair loss. It's available in 2% and 5% (lotion and foam) solutions that are applied to the scalp. In 1988, the U.S. Food and Drug Administration approved Rogaine® for the treatment of hereditary male pattern baldness. The 2% solution is also approved for female pattern hair loss. To use Rogaine®, apply it directly to hair-loss areas of the scalp twice daily. In medical research studies, 40% to 75% of men who used Rogaine® for 12 months reported new hair growth. Among women who used it for eight months, 46% to 60% grew new hair.
Most common side effects
The most commonly reported side effects of Rogaine® are itching and irritation on the treated areas of the scalp. Pregnant or nursing women should not use Rogaine®. Also, people who are age 18 or younger should not use this product unless directed by a doctor. If you don't have a family history of hair loss, or if your hair loss is patchy or sudden, check with your doctor before trying Rogaine®.
