Redken Color Extend Magnetics Sulfate-Free Shampoo is a gentle cleanser that helps colour-treated hair stay vibrant.
This creamy, low-foam shampoo uses a sulphate-free formula to cleanse without stripping your colour. It works by coating each strand with a protective layer, helping lock in colour pigments while removing daily build-up and excess oil.

Ideal for anyone with coloured or highlighted hair who wants their shade to last longer. Use it on wash days to maintain richness between appointments and enjoy hair that looks freshly coloured for longer.
