Kerastase’s Blond Absolu Hydrating Illuminating Shampoo is a lightweight, gentle cleanser designed for bleached, highlighted, or naturally grey hair, helping wash away buildup without harsh brass correction. Powered by Hyaluronic Acid and Edelweiss Flower, it delivers targeted hydration while supporting strength and comfort for hair and scalp. Each cleanse purifies and detoxes to lift pollution, excess oil, and daily impurities, leaving strands softer, smoother, and visibly more luminous. With continued use as part of a routine, hair can look brighter and feel salon-fresh, with users reporting 84% more hydration, up to 11x more resistance to breakage with conditioner, and up to 4x more shine in a cruelty-free formula suitable for everyday use.
