Kérastase First Fundamental Filler Serum

Intensive Resurfacing Repair Serum, Damaged Hair

Kérastase Première Fondamental Filler Serum is a leave-in treatment with multiple benefits.

Intended for all types of damaged hair, this serum helps seal the hair scales to protect them on the surface from heat (up to 230°C), humidity and excess calcium.

Its formula also helps tame frizz for 72 hours for long-lasting, smooth, easy-to-style hair.

This treatment restores strength and suppleness to sensitized hair by filling the fiber.

The calcium present in hard water amplifies hair damage, prevents the scales from closing and breaks the internal bridges of the fiber.

The Première Kérastase hair routine offers a double restorative action to damaged hair by eliminating the calcium overdose and rebuilding the internal bridges of the hair fiber.

The Kérastase Première Fundamental Filler Serum acts by:

- beautifying the fiber by giving it more fluidity and movement

- protecting against heat damage up to 230°C

- providing anti-frizz and anti-humidity action
