Redken Acidic Bonding Concentrate Shampoo is an all-in-one formula designed to repair and nourish damaged and bleached hair. Its concentrated formula targets weak bonds caused by color treatments, perms, or heat styling, which account for 2/3 of hair's strength. By providing proper nutrition for these compounds and restoring the hair's pH balance with citric acid, this shampoo strengthens hair, reduces frizziness and dryness, and minimizes breakage. With regular use, it also helps maintain the color of colored hair. This highly concentrated shampoo repairs and protects hair, with 56% less breakage and 82% less visible split ends. It is suitable for all hair types and textures, including damaged, processed, and colored hair.
