System 2 is formulated for natural, untreated hair with progressed thinning. The shampoo and conditioner are both built around a blend of Niacinamide (Vitamin B3), Biotin, and Caffeine — ingredients 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 on the scalp. The conditioner follows with a lightweight, moisturizing formula that hydrates scalp and hair from root to tip without weighing hair down — important for a system designed to build the appearance of thickness and fullness. Both are clinically and dermatologically tested, with visible thickening results reported in as little as 30 days of consistent use.
