Kérastase is using the golden standard of molecules for blonde hair hydration: HYALURONIC ACID.

Through our Hyaluronic Acid produced by French Biotechnology, we have created the Blond Absolu products with MACRO-[H.A], to perfectly stay on the hair surface, to provide long-lasting moisture and reinforcement.

It acts in a duo with MICRO-[H.A.], able to penetrate the scalp skin to provide long lasting hydration and reinforcement of the scalp's barrier function.
