Première Mask Filler Réparateur is an intensive repair treatment that visibly reverses damage by targeting the root cause of hair brittleness: calcium buildup.
The Porosity Cycle: Open cuticles in damaged hair allow calcium from water to seep deep into the fiber, causing a "stiffening" effect that leads to dullness and snapping.
The Première Masque Filler Réparateur is specifically formulated to break this cycle for porous hair: its dual action rebuilds the hair structure, smooths the surface, and radically reduces breakage, so hair goes back to its healthiest, strongest, most beautiful state.

HOW TO DRAMATICALLY REVERSE PERSISTENT DAMAGE?
Kérastase discovered the reason behind damage that keeps coming back: CALCIUM!
Damaged hair is porous and absorbs 3 times more calcium from water (vs healthy hair) leading to a calcium overdose.
At each contact with water, calcium accumulates creating persistent damage. Calcium sneaks in-between keratin chains, and breaks their links, making hair rigid, stiff and easy to break.
On the outside, calcium builds-up, on the scales, making hair rough and dull.
8% PURE ACIDS CONCENTRATION
Free hair from calcium overdose with Citric Acid, an organic acid that acts from core to surface, to neutralise dullness and stiffness. Once calcium is removed, Glycine, an amino acid, penetrates hair's inner layer to deeply repair. As a result, broken links between keratin chains are reconnected, dramatically reducing breakage.
