Kerastase Premiere Decalcifying Repairing Shampoo (8.45 oz) - The Antidote to Damage, Decalcify and Reclaim Your Strength

Your hair is absorbing an enemy every time you step into the shower, one that goes unseen but makes its damage felt: excess calcium from hard water. Over time, this mineral overdose sneaks past the cuticle, causing internal damage to the keratin chains that are the very backbone of your hair's strength, leading to hair that is stiff, dull, and distressingly prone to breakage. The Kérastase Première Decalcifying Repairing Shampoo is your daily, sophisticated defense and deeply reparative solution, specifically designed to eliminate this persistent calcium buildup while simultaneously restoring your hair fiber to its première state-the way it felt before the damage began. This is the foundational cleanse that prepares all types of damaged hair, from brittle ends to over-processed lengths, for true, lasting regeneration.

This innovative formula leverages a powerful, dual-action complex to reverse damage both inside and out, all within a rich, luxurious, sulfate-free lather. The star is Citric Acid, a high-performance organic acid that actively neutralizes and removes up to 99% of surface and deep-seated calcium deposits, instantly restoring vibrancy and flexibility to stressed strands. Complementing this decalcifying action is the amino acid Glycine, whose small molecular size allows it to penetrate the hair's innermost cortex to reconnect broken keratin links. This revolutionary synergy rebuilds the hair's structural integrity from the core, dramatically reducing breakage and reversing the stiffness caused by mineral accumulation. It is hair science distilled into a professional-grade, creamy shampoo that feels indulgent yet works with clinical precision.

The shower experience itself is a luxurious escape, centered around the captivating "Portofino Summer" signature scent-a luminous blend of zesty mandarin and citrus notes, softened by the delicate floral accord of orange flower and jasmine. Its rich, white creamy texture transforms into a decadent foam that gently, yet effectively, cleanses both the scalp and lengths without stripping color or vital moisture. This essential Bain is optimally used as the second step in the Kérastase Première ritual, layered directly on top of the Concentré Décalcifiant Ultra-Réparateur to maximize the treatment's deep-repair benefits. The result is hair that is not only purified and free of dulling residue but left 73% shinier, twice as smooth, and dramatically strengthened, bouncy, and resilient.
