Kerastase’s Blond Absolu Hydrating Oil Concentrate is a light, milky serum designed to restore bleached and highlighted hair with deep hydration and visible repair, powered by Hyaluronic Acid and Edelweiss Flower Extract. It helps seal the look of split ends, smooths the hair fiber, and delivers mirror-like shine while supporting a balanced, softer feel.With 24-hour anti-humidity care, UV filters, and heat protection up to 230C, it helps defend blonde tones from daily stressors that can dull color and weaken strands. A soft floral-woody scent with a fresh hint lingers subtly, and the refillable 75 ml bottle is made with 30% recycled glass for a more considered daily routine.
