KÉRASTASE Première Anti-Breakage Repairing Mask for Damaged Hair — 6.8 oz, Bond-Repairing & Shine-Enhancing

KÉRASTASE Première Anti-Breakage Repairing Mask is a rich, dual-action treatment that removes calcium buildup while reconnecting keratin links to visibly reduce breakage and smooth damaged hair.

This concentrated repair mask works inside the hair fiber as well as on its surface to restore strength, shine and manageability. Formulated with peptides and glycine, it targets the structural causes of fragility: mineral buildup and broken keratin bonds. Regular use as part of the Première system improves texture and reduces the look of split ends without weighing hair down.

How does this mask reduce breakage?

The formula combines bond-repairing glycine with strengthening peptides to reconnect disrupted keratin chains and fortify strands against mechanical stress. It both repairs internal links and coats the hair surface to prevent future damage during brushing or styling. Clinical comparisons show significant improvement versus non-conditioning shampoo routines.

• Glycine helps relink broken keratin chains inside the fiber.
• Peptides reinforce strand structure for greater tensile strength.
• Removes calcium buildup that weakens hair over time.
• Visible reduction in split-end appearance with continued use.

Will it make my hair smoother and shinier?

Yes — the mask restores surface smoothness while rebuilding inner strength, producing visibly smoother and shinier hair after repeated applications. Its conditioning agents seal the cuticle, improving light reflection for a glossier finish. Results are amplified when used with the rest of the Première collection.

• 7x smoother hair surface reported versus non-conditioned hair.
• 53% more shine measured compared with unwashed hair in trials.
• Seals cuticles to reduce frizz and tangling.

How and when should I use the mask for best results?

Apply the mask after shampooing to towel-dried hair, focusing on lengths and ends, then leave for about five minutes before rinsing. Use once or twice weekly depending on damage level; more frequent use can be beneficial for very compromised hair. Pairing with KÉRASTASE Première shampoo and treatments yields the most consistent improvements.

• Apply to clean, damp hair after shampooing.
• Massage through lengths and ends; avoid roots for fine hair.
• Leave on for approximately five minutes, then rinse thoroughly.
• Use weekly or as needed for maintenance.

Are there measurable benefits from continued use?

Independent assessments reported stronger, smoother and shinier hair compared with non-conditioning routines and unwashed hair benchmarks. While individual results vary with hair type and prior damage, users typically notice reduced breakage and improved manageability after several applications. The mask supports long-term fiber integrity when included in a regular care regimen.

• Up to 98% stronger hair versus non-conditioning shampoo in tests.
• Clinical data shows repeated improvements in texture and resilience.
• Supports ongoing protection against daily mechanical stress.

Who is this for: KÉRASTASE Première Anti-Breakage Repairing Mask is designed for anyone with damaged, brittle or chemically treated hair seeking a concentrated treatment to rebuild strength and smoothness. It suits all hair types that need bond repair and calcium removal — particularly hair exposed to hard water, frequent styling, bleaching or heat. Use it as part of a weekly repair ritual to restore resilience, reduce split ends and achieve a polished, healthy-looking finish.
