For men suffering from hereditary hair loss, Men’s ROGAINE Solution can help regrow hair. The 5% minoxidil solution absorbs quickly into the scalp to reactivate hair follicles, increasing their size and allowing for normal, healthy hair to develop. This treatment is the first FDA-approved topical product proven to help regrow hair in men with hereditary hair loss. After eight weeks of twice-daily use, you may begin to experience regrowth; some users may take up to four months to see results. This package of Men’s ROGAINE Solution includes one 2-ounce bottles, a one-month supply.
