Kérastase Première Concentré Décalcifiant Ultra-Reparateur

Kerastase's first pre-shampoo treatment that removes calcium and repairs all types of damaged hair.

Calcium-rich water can further damage hair that is already delicate due to being over-processed or bleached. Being more porous, damaged hair absorbs a higher amount of calcium than natural hair. The concentration of pure acids in this treatment therefore has a dual action: it decalcifies the hair from this excess calcium and repairs it from within, restoring the hair's strength and improving its stiff and dull appearance.

- Drastically decalcifies and repairs persistent damage.

- Reverses stiffness and dullness

- Reconnects broken bonds between keratin chains to strengthen the internal structure.

- Restores 99% of hair's original strength*.

- Up to +97% reinforced internal structure

- 93% less breakage

- 75% more shine

With its transparent gel texture, this brilliant product drastically repairs persistent damage, mending broken bonds between keratin chains to strengthen the hair's structure. Hair is thus stronger, healthier-looking, and shinier, as if renewed.

Leave Kérastase Concentré Décalcifiant Ultra-Réparateur on, then apply Kérastase Première Bain Décalcifiant Réparateur directly as an additional layer to optimize effectiveness. Rinse, and follow with Première Fondant or Mask.
