Kérastase Sérum Filler Fondamental is a lightweight leave-in treatment to care for all types of damaged hair from the inside out, leaving it glossy and supple. Because of its increased porousness, processed hair absorbs three times more calcium from water than untreated hair, leading to a damaging calcium overdose which is visible inside and outside the hair fiber. Sérum’s dual action 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.
