Product Details

Kérastase Premiere Decalcifying Repairing Pre-Shampoo Treatment is the first pre-shampoo formula that effectively removes calcium from hard water while fully repairing all types of damaged hair. Hard water's calcium can exacerbate damage in porous, over-processed, or lightened hair, which absorbs three times more calcium than natural hair. This concentrated treatment uses pure acids for dual action: decalcifying to eliminate calcium overdose and repairing from within to reconnect broken keratin links, reinforcing hair strength and reversing stiffness and dullness. Its transparent gel texture dramatically restores persistent damage, leaving hair stronger, healthier-looking, and shinier.

For optimal results, apply without rinsing and layer with Kérastase Premiere Bain Decalcifiant Reparateur for enhanced decalcifying and repairing. Complete with Fondant Fluidite Reparateur. This vegan, recyclable treatment (95% recycled plastic bottle) recreates 99% of hair's original strength, reinforces inner structure by +97%, reduces breakage by 93%, and increases shine by 75%.
