Nioxin System 2 Starter Kit is a targeted scalp and haircare regimen formulated for natural, untreated hair experiencing progressed thinning. It uses a blend of active and botanical ingredients — including niacinamide, biotin, caffeine and mint oils — to deliver antioxidants and nutrients to the scalp and hair roots. The formulation is intended to refresh the scalp environment, reduce follicle-clogging buildup, and strengthen hair strands to improve resilience and the appearance of density. Regular use supports scalp health, helps minimize breakage, and promotes fuller-looking hair while providing lightweight protection against environmental stressors. Suitable for fine, natural hair showing signs of progressed thinning, the system focuses on nourishing follicles and improving scalp circulation. Follow product directions for best results; use the regimen consistently (several times per week) and apply topical treatments to the scalp where indicated. Avoid contact with eyes and discontinue if irritation occurs. Consult a dermatologist for persistent hair‑loss concerns or when combining with medicated regrowth treatments.
