8 oz. An herbal DHT Inhibiting Shampoo designed to gently cleanse the scalp of dirt, pollution, and DHT. This unique blend of 11 DHT inhibitors will also help inhibit DHT, which has been found to be the primary cause of hair loss, particularly when used as part of our AK Advanced Hair Growth System™. Growth Support Shampoo helps in promoting healthy follicle stimulation and the production of hair stimulating keratin protein. There will be a noticeable reduction in shedding/thinning as you continue to properly use. This specifically formulated shampoo is free of sulfates, Cocamide DEA, and paraben and helps your hair look stronger, thicker, and provides moisture and shine to all hair types. Our gentle cleanser is used in our Advanced Growth Systems and is typically recommended for balding or excessive thinning.
