System 2 Shampoo is formulated for natural, untreated hair with progressed thinning, built around Niacinamide (Vitamin B3), Biotin, and Caffeine. These ingredients are selected to nourish the hair root, help stimulate hair follicles, and strengthen strands against breakage. The shampoo gently cleanses the scalp to help remove impurities and excess sebum that can clog follicles, while Wild Mint Oil and Peppermint Oil provide a refreshing, circulation-stimulating sensation. Clinically and dermatologically tested, System 2 is designed to gently cleanse without compromising the scalp environment needed for healthy-looking hair. For best results, this shampoo is designed to be used as part of the complete System 2 routine alongside System 2 Conditioner and Scalp Treatment, at least 3 times per week.
