Nioxin by Nioxin NIOXIN AGE DEFENSE SHAMPOO 33.8 OZ for UNISEX

This unisex haircare product is Nioxin by Nioxin NIOXIN AGE DEFENSE SHAMPOO 33.8 OZ for UNISEX. Build-up is the usual reason a product that worked for months appears to stop working. Work it through damp mid-lengths and ends, keeping oils and masks off the roots unless the label says otherwise. Where one is discounted, compare the size and edition rather than the headline alone. A clarifying wash every few weeks clears build-up and lets the rest of the routine work again. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
