Men's Rogaine Thickening 2-in-1 Shampoo + Conditioner is formulated to cleanse the scalp and condition hair in a single step. This minoxidil-free formula contains rosemary oil, keratin, and citric acid to help leave hair looking fuller, support hair strength by helping reduce breakage, and remove scalp buildup. Gentle enough for regular use, it is designed to be used on its own or alongside Men's Rogaine 5% Minoxidil Foam hair regrowth treatment. Apply to wet hair, massage into a lather, and rinse thoroughly.
