KÉRASTASE Première Sulfate-Free Hair Repair Shampoo, 8.5 fl oz — Citric Acid Decalcifying + Strengthening

Kérastase Première Sulfate-Free Hair Repair Shampoo is a dual-action, citric-acid-enriched cleanser that decalcifies mineral buildup and reconnects keratin links to strengthen, smooth and add shine to damaged hair.

If your hair looks dull, feels rough, or breaks more than usual, mineral deposits and weakened keratin can be amplifying the problem. This sulfate-free shampoo from KÉRASTASE’s Première line combines a decalcifying agent with bond-supporting amino acids to remove calcium buildup while helping rebuild internal hair strength. The formula is designed to be gentle on color and fibers while preparing hair for the follow-up repairing conditioner or mask in a complete routine.

How does this shampoo address mineral and calcium buildup?

This shampoo contains citric acid, a chelating ingredient that helps dissolve and lift mineral residues from hard water and styling product buildup. By clearing these deposits, the formula reduces surface roughness and allows subsequent treatments to penetrate more effectively.

• Citric acid targets calcium and mineral films on the hair shaft.
• Sulfate-free surfactants cleanse without stripping necessary moisture.
• Prepares hair for conditioning steps for improved product absorption.

In what way does the product strengthen and reduce breakage?

The shampoo includes glycine, an amino acid that supports reconnection of weakened keratin links within the fiber, which helps lower breakage during brushing and styling. Over repeated use as part of the Première system, KÉRASTASE reports measurable improvements in strength and tensile resilience.

• Glycine targets internal keratin bonds to improve cohesion.
• Restorative action reduces the incidence of split ends and snap-offs.
• Recommended pairing with Première Repairing Conditioner or Mask enhances results.

What visible changes should I expect after using it?

Regular use in a complete regimen can make hair smoother to the touch and increase visible shine while reducing the frequency of breakage. KÉRASTASE cites improvements such as more shine and reduced breakage compared with untreated or non-conditioning approaches.

• Reported up to 73% increase in shine versus unwashed hair when used in system.
• Claims of significantly less breakage compared with non-conditioning shampoo routines.
• Smoother surface feel that improves manageability and styling outcomes.

How should I use the shampoo for best results?

Use the shampoo on wet hair, ideally after the Première Pre-Shampoo Treatment if you use the full system. Massage to emulsify and rinse thoroughly, then follow with the Première Repairing Conditioner or Repairing Mask to lock in repairs and hydration.

• Apply to wet hair and massage until it emulsifies.
• Rinse fully to remove dissolved mineral residues.
• Follow with repairing conditioner or mask for optimal strength restoration.

Who is this for: KÉRASTASE Première Sulfate-Free Hair Repair Shampoo is suited for anyone with hair weakened by chemical services, heat styling, or hard water mineral buildup who wants a gentler, repair-focused cleanser. It’s formulated for all damaged hair types and is a smart choice for color-treated hair owners seeking a non-sulfate option that targets both surface buildup and internal fiber repair when used within the coordinating Première routine.
