KÉRASTASE Sulfate-Free Repair Shampoo — Strengthening & Smoothing for Damaged Hair with Citric Acid & Glycine

KÉRASTASE Première Sulfate-Free Repair Shampoo is a dual-action, strengthening cleanser that removes calcium buildup while reconnecting keratin links to reduce breakage and restore shine.

This salon-grade shampoo combines a gentle sulfate-free base with citric acid and glycine to tackle two common causes of weakened hair: surface mineral buildup from hard water and internally damaged keratin bonds. It cleans without stripping, then targets scale and stiffness from calcium deposits while promoting smoother, more resilient strands. The formula is designed for repeated use as part of the KÉRASTASE Première system for cumulative improvement.

How does this shampoo remove mineral buildup from shower water?

The formula includes citric acid, an ingredient that helps dissolve and lift calcium and other mineral deposits that accumulate on hair over time. By decreasing scale and film on the hair surface, the shampoo restores natural flexibility and allows conditioners and treatments to penetrate better.

• Citric acid targets and loosens calcium buildup from hard water.
• Sulfate-free base cleanses without over-drying or stripping oils.
• Improved product absorption after use for better conditioner performance.

In what way does it strengthen and reduce breakage?

Glycine in the formula supports reconnection of weakened keratin chains, helping hair recover tensile strength from within. Regular use in concert with the Premiere range reconstructs compromised links and reduces fiber fragility, lowering breakage during brushing and styling.

• Glycine helps rebuild bonds inside the hair cortex for added resistance.
• Restores softness and pliability to previously stiff, calcium-affected strands.
• Delivers measurable reduction in breakage when used in the full routine.

What should I expect in terms of shine and smoothness?

By clearing mineral residue and repairing structure, the shampoo improves surface reflectivity and tactile smoothness. Hair looks glossier and feels sleeker after rinsing and responds better to conditioners and masks, producing a noticeable lift in shine and manageability.

• Removes the dulling film that hides natural shine.
• Leaves hair smoother to the touch and easier to detangle.
• Enhances the effect of follow-up conditioning treatments for long-lasting gloss.

How do I use it for best results?

For optimal performance, use the shampoo as the second step layered over the Première Pre-Shampoo Treatment. Apply to wet hair, massage until emulsified, then rinse thoroughly and follow with a repairing conditioner or mask from the same line. Regular use within the full system yields the most consistent strengthening and shine improvements.

• Apply on wet hair after the pre-shampoo treatment for dual-action benefits.
• Massage to create a gentle lather, then rinse completely.
• Follow with Première Repairing Conditioner or Repairing Mask for best results.

Who is this for: KÉRASTASE Première Sulfate-Free Repair Shampoo is formulated for anyone with hair weakened by chemical services, heat styling, or mineral buildup from hard water. It suits all damaged hair types that need both surface decalcification and internal reinforcement—ideal for people seeking salon-level repair in a daily or weekly routine. Avoid use on scalps with specific dermatological conditions without professional advice.
