KÉRASTASE Première Hair Repair Conditioner for Damaged Hair — Softening, Mineral-Removing Formula

KÉRASTASE Première Hair Repair Conditioner is a dual-action conditioner that removes calcium buildup and reconnects weakened keratin links to hydrate, strengthen and restore shine to damaged hair.

This salon-grade conditioner targets two common causes of brittle, dull hair: mineral buildup from hard water and broken internal keratin bonds from mechanical or chemical stress. The formula combines citric acid to lift calcium deposits with glycine to help rebuild keratin linkages, delivering immediate softness and long-term resilience when used as part of a regular haircare routine.

How does it remove calcium buildup without over-drying?

The conditioner uses citric acid at a concentration chosen to dissolve mineral deposits while remaining gentle on the hair fiber. Instead of stripping natural oils, it lifts the white, stiff residue that makes hair feel dry and lackluster, allowing moisture and conditioners to penetrate more evenly.

• Citric acid targets and dissolves calcium and mineral residue from hard water.
• Rinseable formulation avoids harsh detergents or aggressive chelators.
• Leaves hair surface conditioned so following products absorb better.

What rebuilding benefits does the glycine blend provide?

Glycine is included to help reconnect disrupted keratin links inside the hair shaft, reducing breakage and restoring pliability. The effect is cumulative: with continued use, strands become less prone to snapping and more responsive to styling.

• Reinforces keratin chain interactions to reduce breakage.
• Improves hair elasticity and flexibility after a few applications.
• Works alongside conditioning agents for smoother lengths and ends.

How quickly will I see softer, shinier hair?

Immediate tactile improvements are common after the first rinse—hair feels softer and smoother. Clinically measured outcomes in brand testing show notable increases in shine and strength with ongoing use as part of the KÉRASTASE Première system.

• Apply after shampoo to towel-dried hair; leave 3–5 minutes for best results.
• Instant smoothing and manageable feel after first application.
• Progressive shine and reduced breakage with continuous use.

How do I use it within my weekly routine?

Use this conditioner after cleansing with a compatible KÉRASTASE shampoo, especially if you live in a hard-water area or regularly chemically or heat-treat your hair. For most hair types, a few applications per week will maintain the balance between mineral removal and ongoing repair.

• Shampoo hair, towel-dry, then apply through lengths and ends.
• Massage gently and leave on for 3–5 minutes before rinsing thoroughly.
• Follow with styling or other KÉRASTASE treatments as needed.

Who is this for: KÉRASTASE Première Hair Repair Conditioner is designed for people with damaged, brittle or dull hair, and for anyone experiencing stiffness and loss of shine from calcium or mineral build-up. It suits chemically treated, heat-styled or frequently worn hair that needs both surface conditioning and internal bond reinforcement. If you want a targeted, professional-strength conditioner that pairs mineral removal with reparative care, this product sits well in a maintenance routine to restore softness, reduce breakage and enhance luster.
