Kerastase Premiere 1 Decalcifying Repairing Pre-Shampoo Treatment for All Types of Damaged Hair (33.8 oz) Neutralize, Rebuild, and Restore Hair

The Kérastase Paris Première Decalcifying Repairing Pre-Shampoo Treatment in this substantial 33.8 oz size is the essential first step in reversing persistent hair damage, offering a clinical-grade solution to restore hair to its strongest, most radiant self. This potent pre-shampoo, known as the Concentré Décalcifiant Ultra-Réparateur, is a true game-changer because it targets the hidden aggressor that conventional washing often misses: calcium overload from hard water. Damaged hair is exceptionally porous and absorbs three times more calcium than healthy hair, which leads to stiffness, chronic breakage, and a disheartening dullness that no amount of moisturizing seems to fix. Applying this fluid first, before any shampoo, ensures the immediate saturation and removal of this rigidity-inducing buildup.

This groundbreaking formula operates with a dual-action system featuring an incredibly high 8% concentration of Pure Acids working in perfect synergy. First, the high concentration of Citric Acid acts as a powerful decalcifying agent, actively attracting and removing the excessive calcium accumulation both on the surface and deep within the hair fiber, effectively neutralizing the core cause of stiffness. Once decalcified, the amino acid Glycine penetrates the deepest layers of the hair shaft, actively reconnecting broken keratin links to rebuild the internal structure from within. This two-pronged approach delivers astonishing results: hair is left 99% of its original strength recreated* and exhibits *93% less breakage,** making it a non-negotiable step for anyone with chronically damaged, bleached, or over-processed hair looking for a genuine second chance.

This professional-size 33.8 oz (1000ml) pump bottle is the ultimate investment for the long-term health of your hair, ensuring you have a steady supply of this highly concentrated treatment for consistent and transformative weekly use. The liquid texture allows for easy and thorough application, working its magic for a few minutes before you layer on the coordinating Première Bain (shampoo) right over it—no rinsing required between steps! This layering maximizes the decalcifying effect, transforming the daily ritual of hair washing into an unparalleled rebuilding experience. Your hair emerges from the shower feeling profoundly softer, astonishingly flexible, and visibly more resilient, radiating a health and shine that truly earns the "première" title.
