Regaine For Men 5% Extra Strength Hair Foam is a clinically proven topical hair regrowth treatment formulated with 5% Minoxidil to help combat male pattern hair loss by increasing blood flow and nutrient delivery to hair follicles, strengthening follicles, and reactivating hair growth at the root. It works by reversing follicle miniaturization, extending the growth phase of hair, and stimulating follicles to move from the resting phase into active growth, with visible results often seen within weeks of consistent twice-daily use, while the lightweight foam format allows easy application and quick absorption without residue.
