KÉRASTASE Première Repair Pre‑Shampoo Treatment — Citric Acid Decalcifying, Bond‑Rebuilding for Damaged Hair (93% Less Breakage)

This concentrated pre‑shampoo treatment uses citric acid to remove calcium buildup that stiffens and dulls hair, while glycine and bond‑repair technology help reconnect weakened keratin chains. Applied to damp hair before shampooing, the lightweight emulsion is designed to amplify the effectiveness of the following cleansing and conditioning steps so strands feel stronger, smoother and visibly shinier after use.

How does this treatment reduce breakage and restore strength?

The product combines two complementary actions: a decalcifying acid to lift mineral buildup and a bond‑rebuilding ingredient to reconnect broken links in the hair cortex. Together these mechanisms lower mechanical stress on wet and dry hair, which leads to fewer snaps and split ends over time.

• Citric acid removes calcium deposits that make hair rigid and prone to cracking.
• Glycine supports reconnection of keratin links for improved elasticity.
• Clinical figures show dramatic reductions in breakage when used in the full routine.

What is the correct way to use this pre‑shampoo for best results?

Apply generously to damp hair before you shampoo: massage through lengths and focus on areas with stiffness or buildup. Leave the formula on for five minutes, then do not rinse — instead follow immediately with the Première Repairing Shampoo to emulsify and rinse, which maximizes the dual‑action benefit.

• Work on clean, damp hair to ensure even distribution.
• Allow five minutes of contact time for decalcification and bond action.
• Layer with the Première Repairing Shampoo, emulsify, then rinse for full effect.

Which hair concerns will this treatment address most effectively?

This treatment targets signs of long‑term damage caused by mineral buildup, chemical services or frequent heat styling. It is formulated to reverse stiffness and dullness while reinforcing weak bonds, so hair looks healthier and gains noticeable shine and resilience with consistent use.

• Removes mineral deposits that create dull, rigid hair texture.
• Reconnects keratin links to reduce snapping and split ends.
• Enhances surface shine and manageability after the full routine.

Who is this for? KÉRASTASE Première Repair Pre‑Shampoo Treatment is intended for hair that shows persistent mechanical or mineral damage: brittle lengths, reduced elasticity, lackluster surface, or frequent breakage. It’s suitable for anyone wanting to add a targeted, professional‑grade step to their at‑home regimen, especially those who use hard water, regularly color or heat style, or seek to strengthen fragile mid‑lengths and ends. For best outcomes, use as part of the KÉRASTASE Première system and follow the recommended shampoo and conditioning steps.
