Nioxin System 1 Scalp + Hair Shampoo & Conditioner is a complete hair care duo designed to cleanse, fortify, and support the appearance of thicker, healthier-looking hair for those with natural hair or noticeably thinning hair. The System 1 Shampoo gently removes dirt, oil, and follicle-clogging sebum while invigorating the scalp environment. The System 1 Conditioner helps strengthen and hydrate strands, leaving hair more resilient, manageable, and less prone to breakage. Together, this scalp-focused set helps promote an optimal foundation for thicker-looking hair, enhances overall hair texture, and provides balanced moisture without weighing hair down, ideal for fine or thinning hair that needs daily support and a revitalized feel.
