Help hair loss and regrow fuller hair with Men’s Rogaine Extra Strength 5% Minoxidil Topical Solution. Ideal for use at the early stages of hair thinning, this hair regrowth treatment is clinically proven to regrow hair. Unlike hair loss shampoos and hair thickening products that temporarily plump hair from the outside, Rogaine penetrates the scalp to reactivate shrunken hair follicles, allowing for regrowth of hair. The extra strength 5% Minoxidil formula works to boost hair follicle activity and hair protein production, helping to maintain hair density.
