Hard water leaves calcium behind on every strand, and over time that buildup is what makes over-processed hair feel rough and lifeless. The Kérastase Première Duo Gift Set is a limited-edition two-step ritual designed to strip that calcium away and rebuild fibre strength.
Why you will love this Première duo
Infused with purifying citric acid and strengthening glycine, this salon-level duo eliminates excess calcium buildup that weakens over-processed hair while rebuilding fibre strength from within. It includes the Concentré Décalcifiant Ultra-Réparateur pre-shampoo treatment and the Bain Décalcifiant Réparateur sulfate-free shampoo.

What it does
The Concentré pre-treatment works first to dissolve and lift calcium deposits sitting on the hair fibre, then the Bain Décalcifiant shampoo layers over it to cleanse and reinforce strands, leaving hair smoother, with renewed fluidity and a brilliant, glossy finish after every wash.
Who it is for
Anyone with damaged or over-processed hair, particularly in areas with hard water, who wants a repairing routine to restore shine and softness.
