The Kérastase Nutritive 8H Night Repair Serum nourishes dry hair while you sleep – for silky smooth hair in the morning. The night serum contains iris root and a blend of vitamins, which replenish the moisture in the hair overnight and leave the hair shiny when waking up.

The iris root extract balances the daily moisture loss and works its magic over the span of 8 hours. The vitamin blend of Vitamin E, C, B3, B5 and B6 seals the cuticle layer and gives it a silky finish.
