Redken's Color Extend Brownlights Blue Shampoo is a colour-depositing, sulfate-free shampoo for natural or colour treated brown hair.
This hair toner is a blue shampoo that is ideal for colour correcting and neutralising brassy tones on natural and highlighted brown hair, and is great for brunettes who need coverage. Formulated with Citric Acid & Vegetable Protein, this sulfate-free shampoo gently cleanses your hair without stripping colour and helps prolong cool brunette hair colour.
