KÉRASTASE Premiere Hair Repair Conditioner for Breakage & Damaged Hair — Intense Hydration & Bond Repair

KÉRASTASE Premiere Hair Repair Conditioner is a dual-action treatment that removes calcium buildup and rebuilds weakened keratin links to hydrate, smooth and reduce breakage for all damaged hair types.

Designed as the conditioning step in the KÉRASTASE Premiere system, this formula targets two common causes of brittle, dull hair: mineral (calcium) residue from hard water and disrupted keratin bonds. The conditioner combines a clarifying acid with bond-repairing amino technology to soften stiffness, boost manageability and restore visible shine without weighing hair down.

How does this conditioner reduce breakage and reinforce hair?

The product uses glycine-derived actives to reconnect weakened links along the hair’s keratin structure, helping strands resist splitting and snapping during styling. Regular use supports stronger fibers so hair bends and stretches with less damage under tension.

• Bond-repairing glycine-like molecules that reconnect keratin chains
• Clinical results show substantial strengthening compared with non-conditioning shampoo
• Easy rinse-out formula that leaves fibers flexible rather than rigid

What role does it play in removing mineral buildup from shower water?

The conditioner contains citric acid to gently chelate and lift calcium deposits that make hair feel rough and lifeless. By clearing mineral film, cuticles lie flatter and surfaces reflect light more evenly for improved brightness.

• Citric acid action reduces calcium-induced stiffness and residue
• Smoother cuticles mean better shine and easier detangling
• Formulated to work as part of a system for continued buildup control

How will it change texture and manageability after a few uses?

Within repeated applications the conditioner delivers noticeable softness, reduced frizz and a silkier hand-feel, making styling simpler and reducing the need for heat. The formula is crafted to produce smoother strands and enhance slip for less mechanical stress when combing.

• Reportedly up to 7x smoother hair versus non-conditioning shampoo
• Improves detangling and reduces friction during styling
• Leaves hair manageable without heavy residue or limpness

How should I use the conditioner for best results?

Use after shampooing on towel-dried hair: distribute evenly through lengths and ends, leave for 3–5 minutes, then rinse thoroughly. For optimal benefits, incorporate it into the KÉRASTASE Premiere routine and use consistently to maintain calcium control and bond reconstruction.

• Apply to clean, damp hair focusing on mid-lengths and ends
• Allow a 3–5 minute processing time before rinsing
• Pair with the Premiere shampoo and follow-up treatments for system results

Who is this for? KÉRASTASE Premiere Hair Repair Conditioner suits anyone experiencing brittleness, frizz or dullness from chemical or environmental damage and those living with hard water. It’s formulated for all hair types that need strengthening and smoothing without weighing hair down—ideal for people seeking a targeted conditioner that both clarifies mineral buildup and restores fiber integrity for shinier, more resilient hair.

• How to use: Apply to shampooed, towel-dried hair; massage from mid-lengths to ends; leave 3–5 minutes; rinse.
• Key actives: Citric acid for calcium removal, glycine-based bond support for keratin repair.
• Performance highlights: Improved strength, smoother texture and enhanced shine with continued use.
