Kérastase Première Filler Fondamental Repairing Anti-Frizz Serum


A leave-in repairing anti-breakage filler hair serum. This anti-frizz serum works to seal and fill hair strands, and protect them from the heat of styling tools, leaving hair shiny and strong. 90ML

Product Benefits: 

Kérastase Première Sérum Filler Fondamental is a lightweight leave-in treatment for the inner repair of all types of damaged hair, leaving it glossy and supple.

Because of its increased porousness, processed hair absorbs 3 times more calcium from water than untreated hair, leading to a damaging calcium overdose which is visible inside and outside the hair fiber. Kérastase Sérum Filler Fondamental has a dual action: its light, balmy texture seals the cuticles to shield hair’s surface, while filling the fiber and reinforcing hair strength. 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, and hair is left smooth and supple, easy to style.
