Nioxin System 4 Scalp + Hair Shampoo is specially formulated for color-treated, dry, and damaged hair with progressed thinning, delivering a deep cleanse that removes follicle-clogging impurities, excess oil, and environmental buildup. This purifying shampoo helps to refresh the scalp, protect color vibrancy, and improve the overall health of thinning hair. It also supports stronger, fuller-looking strands and preps the hair and scalp for optimal absorption of the accompanying conditioner and leave-in treatment. Ideal as the first step in the complete 3-part System 4 regimen for visibly denser, more resilient hair.

To apply Nioxin System 4 Scalp + Hair Shampoo, begin by thoroughly wetting your hair and scalp. Dispense a small amount of the shampoo into your palm and gently massage it into the scalp using your fingertips, working it through to the ends. Focus on cleansing areas where buildup is most common to help clear away impurities and excess oils. Let the lather sit for a minute to allow the formula to refresh the scalp and support thinning, dry, damaged, color-treated hair. Rinse thoroughly and follow with the System 4 conditioner and leave-in treatment for best results. Suitable for daily use.
