KÉRASTASE Première Sulfate-Free Repair Shampoo, 8.5 oz — Decalcifies & Strengthens Damaged Hair

KÉRASTASE Première Sulfate-Free Hair Repair Shampoo is a decalcifying, strengthening cleanser that smooths damaged hair while removing mineral buildup for stronger, shinier strands.

If your hair looks dull, feels brittle, or snaps easily, mineral buildup and weakened keratin links are often part of the problem. This sulfate-free shampoo from KÉRASTASE’s Première line targets calcium deposits with citric acid while supporting keratin structure with glycine, delivering visible smoothing and measurable strength improvements when used as part of the repair system.

How does it remove buildup without harsh sulfates?

The formula uses citric acid to gently dissolve calcium and mineral residue that accumulates from water and styling products. Because it’s sulfate-free, it cleans without stripping natural oils, preserving moisture and color. This helps hair feel cleaner and less weighed down while avoiding the drying effects of harsh detergents.

• Citric acid targets and reduces calcium buildup.
• Sulfate-free surfactants cleanse gently, maintaining natural oils.
• Leaves hair prepped for deeper conditioning from follow-up products.

What makes this shampoo strengthen and reduce breakage?

The shampoo includes glycine, an amino acid that helps reconnect broken links within keratin chains, supporting the hair’s internal structure. Over repeated use in the full Première routine, laboratories report reduced breakage and improved tensile strength. It pairs best with the Première Pre-Shampoo Treatment and a repairing conditioner or mask for full benefits.

• Glycine helps rebuild keratin linkages to reinforce strands.
• Continuous use with the full system enhances strength restoration.
• Clinically measured reductions in breakage versus non-conditioning formulas.

How will my hair look and feel after using it?

Expect hair to feel smoother, more hydrated, and visually brighter as mineral residue is removed and cuticles are smoothed. KÉRASTASE cites improvements in shine and smoothness when the shampoo is paired with complementary products. Results are most noticeable on previously damaged, chemically treated, or hard-water-affected hair.

• Removes dulling buildup to reveal more reflective shine.
• Smoother texture and easier detangling after conditioning.
• Hydration retained thanks to the gentle, sulfate-free base.

How should I use it for best results?

For optimal repair, apply the Première Pre-Shampoo Treatment first, then layer this shampoo on wet hair. Massage to emulsify and rinse thoroughly, following with a repairing conditioner or a mask. Regular use as part of the Première system delivers the strongest measurable improvements.

• Apply to wet hair after Première Pre-Shampoo Treatment.
• Massage until lather forms, then rinse completely.
• Follow with Première Repairing Conditioner or Repairing Mask.

Who is this for: KÉRASTASE Première Sulfate-Free Hair Repair Shampoo is designed for anyone with chemically processed, heat-stressed, or water-damaged hair seeking a gentler but effective cleansing step that also targets mineral buildup. It’s especially useful if you live in a hard-water area or use styling products frequently, and it works best when combined with the brand’s Pré-Shampoo Treatment and repairing conditioners or masks for a complete strengthening routine.
