Provides heat protection up to 230°C.* Up to 3x smoother hair*, up to 2x softer hair and up to 72-hour anti-frizz*. Kérastase Première Repairing Anti-Frizz Filler Serum is a lightweight leave-in treatment which, when used with the Première routine, helps the inner repair** of all types of damaged hair and restores hair's original strength***, leaving it glossy and supple. Because of its increased porosity, processed hair can absorb up to 3 times more calcium from water than untreated hair, leading to a damaging calcium overdose which is noticeable inside and on the outside of the hair fibre. Kérastase Repairing Anti-Frizz Filler Serum has a dual action: its light, balmy texture helps seal the cuticles to shield hair's surface, while coating the fibre to help fill external damage. Your hair is protected from the calcium damage of hard water, as well as from humidity, and heat up to 230°C*. Frizz is eliminated for up to 72H*, hair is left smooth and supple, and easy to style. For even more care for your bleached or damaged hair, combine with the rest of the Première range. Try the power of the layering technique: start with the pre-shampoo treatment, Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment, then without rinsing off the treatment, use the Kérastase Première Decalcifying Repairing Shampoo on top. Follow with the conditioner or mask before applying the Kérastase Première Repairing Anti-Frizz Filler Serum as a final repair step. *Instrumental test. ** Instrumental test after continues use of full Première routine. ***Instrumental test on bleached hair after continued use of the full Première routine vs. non- bleached hair.
