Kerastase Premiere Decalcifying Repairing Pre-Shampoo Treatment (8.45 oz) - Reset the Damage, Restore the Premiere Strength

Meet the ultimate first step in reversing the cycle of persistent damage: the Kérastase Première Concentré Décalcifiant Ultra-Réparateur. For too long, you have been battling an invisible enemy every time you wash your hair-calcium from hard water, which causes internal breakage and leaves your strands stiff, dull, and brittle. Damaged hair is more porous and absorbs up to three times more of this dulling mineral than healthy hair, shattering the inner keratin links that are responsible for your hair’s strength and vitality. This innovative, transparent pre-shampoo gel is your high-performance deep-sea dive, formulated as the critical Step 1 in the Première layering ritual to dramatically neutralize and remove that devastating calcium overdose before the cleansing even begins.

This is sophisticated damage control, offering a dual-action formula built around a powerful 8% concentration of pure acids. First, the organic acid Citric Acid acts as a brilliant decalcifier, working from the surface deep into the hair fiber to actively eliminate the calcium deposits that cause rigidity and dullness. Then, the amino acid Glycine penetrates the deepest layers of the hair’s cortex to reconnect broken keratin chains, reinforcing the fiber’s internal structure from the inside out. This proprietary synergy works to restore up to 99% of your hair’s original strength, fundamentally rebuilding and fortifying your hair’s architecture rather than just coating the problem. This pre-treatment instantly transforms your hair into a receptive canvas, allowing the products that follow to penetrate deeper and deliver maximum restorative benefits.

The ritual itself is a moment of luxurious, anticipatory repair-simply apply generously to wet lengths before stepping under the water, massage it in, and leave on for five transcendent minutes. The rich, enveloping texture immediately begins its work, filling and sealing the fiber while surrounding you in the luminous "Portofino Summer" scent-a delicate accord of bright mandarin, zesty citrus, and calming orange flower. Do not rinse the concentrate! Layer the matching Première Bain Decalcifying Repairing Shampoo directly on top to maximize the dual decalcifying and repairing action before rinsing out both. You will feel an immediate difference in texture, elasticity, and shine; this pre-shampoo powerhouse is the secret to breaking the cycle of damage, delivering a powerful anti-breakage effect, and revealing strands that are 93% less prone to snapping, brilliantly shiny, and incredibly resilient.
