Color Maintainer Shampoo is formulated for color-treated hair, built around Hydrolyzed Milk Protein, Hydrolyzed Wheat Protein, and Milkshake's proprietary Integrity 41® complex. Milk Protein provides deep conditioning, while Integrity 41® contributes antioxidant protection to help defend hair from stress factors that threaten color intensity and shine. Guar Hydroxypropyltrimonium Chloride and Cocamide MEA act as conditioning agents that help detangle and smooth during the wash, while Hydroxypropyltrimonium Hydrolyzed Casein contributes additional protein conditioning. The shampoo is paraben-free and formulated with color longevity as a core focus. Suitable for daily use, the shampoo is designed to be followed with Color Maintainer Conditioner as part of a complete color-care routine.
