Kérastase Première Concentré Décalcifiant Ultra-Réparateur

Pre-Shampoo Treatment for Damaged Hair Repair

Available in Canada

For

All types of damaged hair, especially over-processed, colour-treated, bleached, brittle, dull, stiff, porous, or breakage-prone hair affected by calcium buildup from hard water.

Description

Kérastase Première Concentré Décalcifiant Ultra-Réparateur is a dual-action pre-shampoo treatment designed to decalcify and repair damaged hair before cleansing. Damaged hair can absorb more calcium from shower water, leaving it feeling stiff, dull, rough, and more prone to breakage. This powerful pre-treatment helps remove calcium buildup while repairing the hair from the inside out.

Formulated with citric acid and glycine, this professional treatment helps restore strength, softness, shine, and fluidity to damaged hair. Kérastase describes the formula as helping remove calcium buildup, repair bonds, and leave hair stronger, shinier, and healthier-looking.

Who It’s For

Perfect for anyone with hair that feels damaged, over-processed, bleached, fragile, dull, stiff, rough, porous, or weakened from colour services, heat styling, chemical treatments, or hard water exposure.

What It Does

• Removes calcium buildup from damaged hair
• Helps repair and strengthen the hair fibre
• Targets stiffness, dullness, and roughness
• Supports softer, smoother, shinier hair
• Helps reduce the look and feel of breakage-prone hair
• Prepares hair for the Première shampoo and treatment ritual

Formula

A concentrated pre-shampoo repair treatment powered by citric acid and glycine. Citric acid helps dissolve calcium deposits that can make damaged hair feel stiff and dull, while glycine helps support repair and a stronger-feeling hair fibre. Kérastase positions this treatment as a dual-action formula that decalcifies and repairs hair before shampoo.

How To Use

Apply generously to wet lengths before shampooing. Massage throughout the hair and leave on for 5 minutes. Do not rinse. Layer Kérastase Première Bain Décalcifiant Réparateur Shampoo directly on top, lather, then rinse thoroughly. Follow with Kérastase Première Fondant Fluidité Réparateur Conditioner or Première Masque Filler Réparateur.

When To Use

Use as the first step in your wash routine when hair feels damaged, brittle, stiff, dull, rough, or weakened by hard water, colour, lightening, heat styling, or chemical services.
