Specifically formulated for medium to thick colour-treated hair, the Kérastase Bain Riche Chroma Respect Refill Pouch is a gentle shampoo designed to help cleanse the lengths while maintaining colour vibrancy. The smoothing formula is enriched with an intensely nourishing blend of glycerin and hyaluronic acid, working to infuse the hair with moisture, while amino acids lend fortifying benefits. Complete with alpha-hydroxylated acid, an ingredient believed to be able to trap dulling minerals, the hair is left feeling irresistibly silky with a radiant shine. Packaged in a refill pouch made with 82% less plastic*. *versus two Kérastase 250ml shampoo bottles.
