System 1 is formulated for natural, untreated hair with light thinning. The shampoo and conditioner are built around Wild Mint Oil, Peppermint Oil, and Niacinamide, ingredients selected to gently cleanse the scalp of excess sebum and impurities that can clog follicles while providing a refreshing, circulation-stimulating sensation. The shampoo also contains Salicylic Acid to help support scalp exfoliation, while the conditioner follows with a lightweight formula built around Niacinamide, Biotin, and Camellia Sinensis Leaf Extract to nourish and hydrate without weighing hair down. Both are clinically and dermatologically tested, with visible thickness and fullness results reported in as little as 30 days of consistent use, at least 3 times per week.
