Kerastase First Bath Decalcifier Repairer
is a decalcifying shampoo and repairer for all types of hair treated or damaged.
A creamy white shampoo that turns into a sumptuous foam, its double action contrasts the excess of hard water calcium that attacks already damaged or bleached hair, leaving them off and stiff.

Without sulfates gently cleanses the scalp and hair by eliminating calcium, which further weakens sensitized hair.
Benefits:
- The hair is repaired from the inside,
- the rupture is reduced and their appearance restored.
- repairs the broken bonds between the keratin chains inside the hair stem, repairing it deep.
- The hair is soft, shiny and bright.

Kérastase First Basic Filler Serum is a light leave-in treatment for internal repair of all types of damaged hair, leaving them shiny and elastic.

Due to their greater porosity, sensitized hair absorbs a higher amount of calcium from the water than untreated hair, causing a harmful excess of calcium visible inside and outside the hair fiber.

Kérastase Sérum Filler Fundamental has a double action:
- its light texture seals the cuticles to protect the surface of the hair
- fills the fiber and strengthens its strength.The hair is protected from hard water calcium damage, moisture and heat up to 230°C.
- The crisp effect is eliminated and the hair remains smooth and elastic, easy to manage.
