Kérastase Blond Absolu Sérum Cicanuit regenerates and nourishes lightened or highlighted hair overnight. This lightweight, non-greasy serum works while you sleep to strengthen the fiber, reduce breakage, and smooth roughness. Infused with Hyaluronic Acid and Edelweiss Flower, it deeply hydrates and softens sensitized strands. Wake up to visibly revitalized, shinier, and more manageable blonde hair — no need to rinse. Directions: Apply 2–4 pumps to dry hair before bedtime. Distribute evenly through mid-lengths and ends. Leave in overnight. No need to rinse in the morning — style as usual.
