KÉRASTASE Première Repair Pre‑Shampoo Treatment for Damaged Hair — Citric Acid Decalcifying & Glycine Strengthening (150ml)

KÉRASTASE Première Repair Pre‑Shampoo is a dual‑action pre-wash treatment that removes calcium buildup and reconnects weakened keratin links to visibly strengthen and smooth damaged hair.

This concentrated pre‑shampoo step is formulated with citric acid to decalcify hair fibers and glycine to rejoin broken keratin bonds, helping reduce breakage and restore shine. Designed to be used before your regular shampoo, it targets persistent mineral buildup and structural weakness that make hair stiff, dull and prone to snapping. Use it as part of the Première system to optimize the results of follow-up shampoo and conditioners.

How does this pre‑shampoo reduce breakage?

The formula reduces hair fiber fragility by addressing two common causes: mineral buildup and broken internal links. Citric acid lifts calcium deposits that stiffen the strand, while glycine works on reconnecting weakened keratin chains so fibers flex rather than fracture.

• Removes calcium build‑up that increases stiffness
• Reinforces internal keratin links with glycine
• Clinically shown to reduce breakage compared to non‑conditioning shampoo

When and how should I use the treatment for best results?

Apply the treatment generously to damp hair before shampooing, leave it on for around five minutes, and do not rinse it out before you layer the Première Repairing Shampoo on top. Massaging and emulsifying with the shampoo lets the two formulas work together, then rinse thoroughly.

• Use on wet hair prior to shampooing
• Leave on for approximately five minutes
• Do not rinse before applying the repairing shampoo

What improvements can I expect after using it once or repeatedly?

After a single application, hair may feel softer and look glossier as surface stiffness is reduced. With continued use within the full Première routine, hair strength and shine continue to improve while breakage is notably lowered, helping hair appear healthier over time.

• Immediate reduction in stiffness and increased manageability
• Boost in shine versus unwashed hair
• Progressive restoration of strength with regular system use

Is this safe for colored or chemically treated hair?

Première Repair Pre‑Shampoo is developed to treat weakened and chemically altered hair by working on structural integrity and removing mineral deposits. It is compatible with color‑treated hair, but always patch‑test or consult your stylist if you have recently undergone intensive chemical services.

• Formulated for weakened and damaged hair types
• Helps restore flexibility without aggressive stripping
• Suitable alongside color, with professional guidance if needed

Who is this for: KÉRASTASE Première Repair Pre‑Shampoo is aimed at anyone whose hair looks dull, feels rigid, or snaps easily — especially hair exposed to hard water, frequent styling, or chemical processes. If you need a targeted pre‑wash step to remove mineral buildup and reinforce hair from the inside out, add this treatment to your routine before your repairing shampoo and conditioner.
