Kérastase Première Concentré Décalcifiant Ultra-Réparateur

Decalcifying Pre-Shampoo Treatment for Damaged Hair

Available in Canada at Curious Salons

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

A ritual of renewal before the cleanse begins. Kérastase Première Concentré Décalcifiant Ultra-Réparateur is a dual-action pre-shampoo treatment that decalcifies and repairs damaged hair before shampooing. When hair is compromised, it absorbs more calcium from shower water — leaving it stiff, dull, rough, and prone to breakage. This powerful pre-treatment dissolves that buildup while repairing the fibre from within, restoring strength, softness, and luminous fluidity.

Who It’s For

Ideal for anyone whose hair feels damaged, over-processed, bleached, fragile, dull, stiff, rough, or weakened by colour services, heat styling, chemical treatments, or hard water — a common concern across Canada.

What It Does

• Removes calcium buildup from the hair fibre
• Repairs and strengthens from the inside out
• Targets stiffness, dullness, and roughness
• Supports softer, smoother, shinier hair
• Reduces the appearance of breakage-prone hair
• Prepares hair for the full Première ritual
• Leaves hair feeling renewed, fluid, and beautifully transformed

How To Use

Apply generously to wet lengths before shampooing. Massage throughout 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 Première Fondant Fluidité Réparateur Conditioner or Première Masque Filler Réparateur.

When To Use

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