KÉRASTASE Première Repair Pre-Shampoo Treatment — Citric Acid Decalcifying & Bond-Repair for Damaged Hair, 93% Less Breakage

KÉRASTASE Première Repair Pre-Shampoo is a dual-action, pre-wash treatment that removes calcium buildup and reconnects weakened keratin links to visibly reduce breakage and restore shine.

This concentrated pre-shampoo treatment from KÉRASTASE targets the causes of persistent hair damage rather than masking them. Its citric acid-based formula decalcifies mineral buildup that stiffens hair, while glycine helps reconnect broken protein links inside the fiber. Used as the first step of the Première Repair routine, it prepares hair to accept the repairing shampoo and conditioners that follow.

How does this treatment reduce breakage in just one use?

The formula combines descaling and bond-repair actions: citric acid dissolves calcium deposits that make hair brittle, and glycine targets the internal bonds that are fractured by chemical or mechanical stress. Together these actions make hair more flexible and less prone to snapping during combing or styling.

• Citric acid removes mineral buildup for improved hair pliability.
• Glycine reconnects weakened keratin links inside the fiber.
• Clinical-style results reported: up to 93% less breakage versus a non-conditioning shampoo.
• Works as a pre-shampoo step to maximize the following repair products.

What is the right way to use the Première Pre-Shampoo for best results?

Apply generously on towel-damp hair before shampooing and massage across roots to ends, ensuring full coverage. Leave the treatment on for five minutes—do not rinse—and follow immediately with the Première Repairing Shampoo to emulsify and remove deposits while continuing the repair process.

• Work through damp hair, section if needed for even coverage.
• Leave on five minutes; do not rinse before shampooing.
• Layer with Première Repairing Shampoo, then massage, emulsify and rinse.
• Use as part of the complete KÉRASTASE Première Repair system for ongoing results.

Which visible improvements can I expect and how quickly?

Visible texture and strength improvements can be noticed after a single application because the product removes stiffening buildup and begins to reconnect internal bonds. With ongoing use as part of the full Première Repair regimen, hair can regain strength and refractive shine while feeling softer and more manageable.

• Immediate effect: reduced stiffness and easier detangling after one use.
• Short term: reports of up to 75% more shine compared with unwashed hair.
• Longer term: restored strength up to 99% with the full system and regular use.
• Significant reduction in breakage versus non-conditioning shampoos.

Who is this product for? KÉRASTASE Première Repair Pre-Shampoo is formulated for hair that has been weakened by mineral buildup, chemical services, heat styling, or mechanical stress and needs targeted, non-invasive repair. It benefits those who want a pro-level pre-wash step to remove calcium deposits and start rebuilding internal bonds before cleansing. Ideal for clients seeking improved strength, less breakage, and enhanced shine without heavy residue—particularly fine to medium textured hair that shows stiffness, dullness or frequent snapping.
