Kérastase Premiere Concentre Decalcifiant Ultra-Repairing Pre-Shampoo Treatment 250ml

The Kérastase Première Concentré Décalcifiant Ultra-Réparateur is a professional-grade, decalcifying repairing pre-shampoo treatment designed for all types of over-processed or damaged hair. This 250ml intensive formula is the ultimate prerequisite for reversing persistent damage caused by calcium buildup from hard water.

Infused with a potent 8% concentration of pure Citric Acid and Glycine, this dual-action treatment works to decalcify the hair fiber from the inside out. Citric Acid acts as a powerful chelating agent to neutralize calcium overdose, which often makes hair brittle and prone to breakage. Simultaneously, Glycine—a small amino acid—penetrates the hair's inner layers to reconnect broken keratin bonds, significantly reinforcing hair strength and elasticity.

This transparent, gel-like treatment should be applied before shampooing to dry or damp hair. It effectively removes excess calcium that weighs hair down and makes it dull, restoring the hair's original movement and vitality. With its signature luxury citrus fragrance, it prepares the hair for the subsequent steps of the Première routine, leaving strands feeling up to 99% stronger and visibly healthier with a radiant, supple finish.

Who is this Product Suitable For:

• Damaged & Over-Processed Hair: Specifically engineered for hair weakened by bleaching, coloring, or heat styling.
• Hard Water Areas: Ideal for those living in regions with high mineral content in the water supply.
• Brittle Hair: Perfect for strands that feel rough, stiff, or snap easily.
• All Hair Textures: Designed to work effectively on fine, medium, and coarse hair types.

Product Benefits:

• Calcium Neutralization: Effectively decalcifies the hair to stop the cycle of persistent damage.
• Intense Repair: Reconnects broken keratin links for significantly stronger hair fibers.
• 99% More Strength: Clinically proven to restore the hair to its original strength and resilience.
• Anti-Dullness: Restores shine and softness by removing mineral buildup.
• Pre-Shampoo Action: Deeply treats the hair before the cleansing process for maximum efficacy.

How to Use:

Apply generously to wet hair lengths before shampooing and massage in. Leave on for 5 minutes. Do not rinse. Layer the Première Bain Décalcifiant Réparateur directly on top to maximize the repairing effect. Lather and rinse both products together thoroughly. For the ultimate transformation, follow with the Première Masque or Fondant.
