Color Smoothing Shampoo - 12oz

What you are looking at is Color Smoothing Shampoo - 12oz by Keratin Perfect, a haircare product. Build-up is the usual reason a product that worked for months appears to stop working. Rinse thoroughly — residue left in the hair dulls it more than hard water does. Discounted listings come and go, and rarely at the same shop twice. A clarifying wash every few weeks clears build-up and lets the rest of the routine work again. The cheapest listing is not automatically the best deal: delivery and any code applied at checkout decide that.
