Help treat hair loss and regrow fuller hair with Men's Rogaine 5% Minoxidil Topical Foam. Ideal for use at the early stages of hair thinning, this hair regrowth treatment is clinically proven to regrow up to 25% more hair in 12 weeks. 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 5% Minoxidil formula works to boost hair follicle activity and hair protein production, while Tricho-Prime Technology uses a proprietary combination of ingredients to create an optimal environment for hair regrowth. It comes in a no-mess foam that is easy to use and is designed to fit easily into your routine. Based on hair count among men and women in clinical studies performed for FDA approval, Jan 2006.
