Kerastase Premiere Decalcifying Resurfacing Concentrate for All Types of Damaged Hair (13.52 oz) - The Ultimate Strength Reset, Decalcify, Regenerate

Your hair has been quietly suffering from an invisible aggressor: calcium overdose from hard water. Every time you step into the shower, this mineral is absorbed by your damaged and porous hair fibers, sneaking past the cuticle to shatter the inner keratin links that define your hair’s strength and resilience. The result is hair that is stiff, brittle, and perpetually dull. This Kérastase Première Decalcifying Resurfacing Concentrate is the luxurious, professional-grade intervention you have been waiting for-an intense, rinse-out liquid treatment specifically formulated for all types of damaged hair that is ready to break the cycle of breakage and brittleness. This is where your hair’s strength reset begins, lifting the accumulated mineral veil to reveal the healthy fiber underneath.

The scientific brilliance of this concentrate lies in its potent, dual-action formula, featuring a high concentration of pure acids for deep repair. Citric Acid acts as a powerful chelator, working from the core to the surface to actively neutralize and eliminate that stubborn calcium overdose that causes rigidity. Following this decalcifying action, the amino acid Glycine penetrates the hair's deepest layers to reconnect those broken keratin links from the inside out. This proprietary technology fundamentally reverses persistent damage, reconstructing the hair's architecture to make its inner structure 97% more resilient. It is this revolutionary interior reinforcement that translates directly to a reduction in breakage and a profound return to the hair's natural strength and flexibility.

This treatment is designed as a crucial part of the powerful Première layering ritual, applied after the Pre-Shampoo Treatment but before the Anti-Breakage Repairing Filler Mask for a supercharged, salon-quality experience at home. Its fluid, resurfacing texture quickly saturates the hair without feeling heavy, sealing the fiber's surface to smooth and protect it from future calcium damage and aggressions. As you indulge, the sophisticated "Portofino Summer" signature scent-a bright, vibrant harmony of mandarin, citrus, and orange flower-elevates the process. The immediate, tangible result is nothing short of transformative: up to 93% less breakage, 4 times softer hair, and a visibly healthier, shinier appearance that finally returns your hair to its original, première state of powerful health.
