Kérastase Première Bain Décalcifiant Réparateur
A sulfate-free professional-level shampoo designed for all types of over-processed or damaged hair. It gently cleanses the scalp and hair while removing calcium buildup caused by hard water, which weakens treated hair and leads to dullness, limpness, and breakage.
The creamy white formula transforms into a luxurious foam that targets calcium overload, protecting hair from further damage. It repairs keratin bonds within the hair shaft, restoring strength and improving hair health from the inside out.
Results include smoother texture, improved manageability, increased shine, and reduced breakage.
