The first Kerastase pre-shampoo treatment that removes calcium and repairs all types of damaged hair.
Calcium-rich water can further damage already delicate hair caused by excessively processed or bleached hair. Being more porous, damaged hair absorbs a greater amount of calcium than natural hair. The concentration of pure acids in this treatment therefore has a dual action: it decalcifies the hair of this excess calcium and repairs it from within, restoring its strength and improving its stiff and dull appearance.
- Dramatically decalcifies and repairs persistent damage.
- Eliminates stiffness and dullness.
- Reconnects broken bonds between keratin chains to strengthen the internal structure.
- Restores 99% of the hair's original strength*.
- Up to +97% strengthened internal structure**Instrumental test after 6 applications of Première Concentré + Bain + Fondant/Masque **Instrumental test after Concentré 93% less breakage** 75% more shine**
With its transparent gel texture, this brilliant product drastically repairs persistent damage, repairing the broken bonds between the keratin chains to strengthen the hair structure. Hair is therefore stronger, healthier-looking and shinier, as if renewed.
Leave Kérastase Concentré Décalcifant Ultra-Réparateur on and then apply Kérastase Première Bain Décalcifant Réparateur directly as an additional layer to optimize its effectiveness. Rinse and follow with Première Fondant or Mask.
