Introducing the Kérastase Première Concentré Décalcifiant Ultra-Réparateur, a pioneering pre-shampoo treatment designed to remove calcium and repair damaged hair.
This unique treatment targets the specific needs of over-processed or bleached hair, which is more susceptible to damage from hard water calcium. Its concentrated pure acid formula performs a dual action: it removes excess calcium that makes hair stiff and dull, and deeply repairs hair from the inside out. The transparent gel texture works to reconnect broken keratin links, significantly enhancing hair strength and structure. For a complete hair transformation, use in conjunction with Kérastase Première Bain Décalcifiant Réparateur and follow with Fondant Fluidité Réparateur. Hair emerges revitalised, stronger, and radiantly shiny, visibly healthier and rejuvenated.
