Kerastase Resistance Extentioniste Hair Mask 200ml

The Kerastase Resistance Extentioniste Hair Mask 200ml provides targeted treatment for damaged hair, aimed at infusing strength and vitality into every strand. Formulated with Creatine R and Acid Maleic, this mask strengthens the fiber structure, restoring resilience to promote longer, healthier hair. Experience deep nourishment with noticeable improvements in hair strength and manageability.

Key Benefits and Features
  • Strength & Resilience: Reinforces hair fibers from within, reducing breakage and supporting longer, healthier-looking lengths.
  • Deep Conditioning & Hydration: Infuses rich moisture into damaged strands, leaving hair softer and easier to manage.
  • Fiber Structure Reinforcement: Creatine R and Acid Maleic collaborate to strengthen the cortex, restoring hair resilience and reducing future damage.
  • Manageability & Shine: Smooths the cuticle for a sleeker texture and natural, healthy-looking shine.
  • Damage Prevention: Shields hair from daily styling stress, chemical exposure, and heat, supporting healthier ends over time.
Who It’s For

This hair mask is designed for damaged, brittle, and over-processed hair in need of strength and resilience. Ideal for those looking to maintain length while minimizing breakage, particularly effective for individuals who regularly expose their hair to chemical treatments or heat styling. Suitable for all hair types; thinner hair should use a small amount on mid-lengths to ends, while thicker hair may benefit from more product and a longer leave time.

Key Ingredients
  • Creatine R: Strengthens hair fibers from within, reinforcing the cortex to mitigate breakage.
  • Acid Maleic: Enhances cuticle conditioning and boosts resilience for smoother, more manageable hair.
  • Fiber Reinforcement Technology: A unique approach to fortify the hair's internal structure, improving long-term strength.
How to Use
  • Step 1: After shampooing, gently towel-dry hair to remove excess water.
  • Step 2: Apply a generous amount of the mask to mid-lengths and ends, avoiding the scalp. Distribute evenly.
  • Step 3: Leave on for 5–10 minutes for deep conditioning, then rinse thoroughly.
  • Step 4: Follow with your preferred styling routine. For optimal results, pair with Kerastase Resistance Extentioniste shampoo and serum as part of a full-strengthening regimen.

Why our stylists rate it
From the Partners Hair team
Kérastase Resistance Masque Extentioniste is a length-strengthening hair mask for damaged hair seeking healthy growth. Part of the Kérastase Resistance range. Highly concentrated weekly treatment that intensively repairs breakage points and seals split ends at the lengths.

Best for: weakened, damaged hair growing through to longer lengths that needs more than a daily conditioner can deliver; hair with visible split ends, frayed lengths, or repeated breakage; the weekly intensive treatment step in the Extentioniste long-hair routine, in place of Fondant Extentioniste once a week or as needed.
Less suited to: severely damaged or chemically over-processed hair needing deeper internal reconstruction (use Kérastase Resistance Thérapiste — Masque Thérapiste); hair primarily concerned with general damage rather than length (use Resistance Masque Force Architecte); hair primarily concerned with dryness (use Kérastase Nutritive — Masque Magistral or Masquintense); colour-treated blonde hair (use Blond Absolu Cicaextreme or Masque Ultra-Violet).

Key actives:
- Créatine R Complex — Creatine + Ceramide; rebuilds the internal hair fibre structure and reseals the damaged cuticle
- Amodimethicone — film-forming conditioning silicone that smooths and protects the hair surface
- Behentrimonium-based emollients — soften and detangle even very damaged lengths
- Hydroxypropyl Guar — supports detangling and slip

Benefits:
- Intensively reinforces damaged lengths and ends
- Seals split ends and reduces visible damage at the tips
- Restores softness, smoothness, and shine to brittle hair
- Improves manageability and detangling for fragile lengths
- Supports the lengthening process — works as the weekly intensive complement to Bain and Fondant Extentioniste

How to use: After shampooing with Bain Extentioniste, apply to clean, towel-dried hair, focusing on mid-lengths and ends. Avoid the roots. Leave on for 5–10 minutes. Rinse thoroughly. Use weekly, or more often as needed for heavily damaged lengths, in place of Fondant Extentioniste.

Format: 200ml mask. Also available in 500ml professional/salon size.
