Kérastase Chronologiste Overnight Youth Serum

A luxurious overnight leave-in hair serum designed to target five visible signs of hair ageing: dryness, dullness, frizz, lack of volume, and reduced thickness.

Infused with Pro-Xylane™ and Ochrophyta Algae, its lightweight, fast-absorbing formula helps nourish and revitalize hair while you sleep. Wake up to smoother, shinier, stronger-looking hair with improved body and softness.
