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 fast-working hair loss treatment is clinically proven to regrow up to 25% more 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. The 5% Minoxidil formula works to boost hair follicle activity and hair protein production, allowing for regrowth of hair. This hair thinning treatment comes in a topical solution that is easy to use: Simply apply 1 milliliter directly to your scalp twice daily and massage it through your hair. And like all Rogaine products, it is designed to fit easily into your routine.
