Kérastase Première Repairing Anti-Frizz Filler Heat Protecting Hair Serum deeply repairs all levels of damage for all hair types, protecting against further breakage. This includes damage from heat styling, over-processing, colour treatment, bleaching, and even water in your shower.

Formulated with a concentration of Peptides, this professional leave-in Serum penetrates hair’s inner layer, to help deeply repair and refill hair surface. With its white balmy texture, the leave-in Serum helps seals the cuticles of damaged hair, while filling over external damage to the fibre and protecting against heat up to 230°C. Hair is left glossy and supple. Think of it like a skincare routine for your hair.
