Hydrating skincare serum, now for hair. New Blond Absolu 2% Pure Hyaluronic Acid Serum by Kérastase is a hydrating, repairing blonde hair and scalp serum.

It’s the ultimate blonde repair serum for bleached blondes, as it contains Hyaluronic Acid – with our highest concentration of Macro and Micro Hyaluronic Acid – to repair the surface damage of hair and moisturise both scalp and hair. The lightweight texture of this clear gel serum preserves the scalp barrier, leaving only a feeling of comfort.

Tested on freshly lightened hair, this Kérastase serum repairs 20% of surface damages in one use*, for stronger blonde hair, that is replenished, plumper and intensely hydrated. Just like with skincare, you can layer 2% Pure Hyaluronic Acid Serum with Blond Absolu Huile Cicaextreme hair oil, to seal in the hydration, for ultimate repair.

First, wash your hair with shampoo and conditioner. Apply 3-7 doses of the Blond Absolu to towel-dried hair and leave in.
