Regaine 2% Topical Solution contains minoxidil and is designed to treat hereditary hair loss in both men and women. This clinically proven formula helps stop and reverse hair loss by stimulating hair follicles and promoting new hair growth. The 2% minoxidil solution should be applied directly to the scalp twice daily. Results may be visible after regular use for several months, though individual results may vary. This is a topical treatment that works by increasing blood flow to hair follicles and extending the growth phase of the hair cycle. For best results, the scalp should be clean and dry before application.
