Kérastase Première Concentré Décalcifiant Ultra-Réparateur Hair Treatment

A professional intensive pre-shampoo hair treatment specially formulated for damaged, over-processed, and color-treated hair. It targets and removes excess calcium buildup caused by hard water, which can weaken the hair fiber and increase breakage. Enriched with Citric Acid and Glycine, it helps decalcify the hair fiber while deeply repairing and reinforcing its internal structure.

Its advanced formula restores strength, flexibility, softness, and shine while significantly reducing breakage, leaving the hair healthier, smoother, and easier to manage from the very first use.
