Premiere - Concentre Decalcifiant Ultra-Reparateur Repairing Treatment - 33.8oz

Kerastase's Premiere Decalcifying Repairing Pre-Shampoo Treatment uses wisteria extract and a citric acid blend (8% concentration of pure acids) to lift calcium and mineral buildup from hard water, helping decalcify the hair surface so repair can reach the fiber level. Applied before shampooing, it supports dual-action repair by bonding weakened zones and smoothing rough cuticles, making hair easier to comb, style, and manage while reducing fragility.With regular use, it can deliver up to 75% more shine and 93% less breakage, leaving damaged hair visibly smoother, stronger, and more resilient to daily styling and environmental stressors over time.
