Product Overview

The Kérastase Resistance Masque Extentioniste is a professional-grade strengthening hair mask designed to restore vitality to damaged hair. Infused with proteins, this mask works to detangle, seal split ends, and reinforce the hair fiber from within. Ideal for all hair types, it delivers intense nourishment without weighing hair down, leaving strands smoother, stronger, and more resilient.

Key Features and Benefits

  • Protein-Enriched Formula: Helps repair and strengthen damaged hair by replenishing lost proteins, reducing breakage and split ends.
  • Detangling Action: Smooths knots and tangles for easy comb-through, minimizing further damage during styling.
  • Split End Sealing: Seals frayed cuticles to prevent further splitting, promoting healthier-looking ends.
  • Suitable for All Hair Types: Safe for color-treated, chemically processed, and natural hair.
  • Lightweight Texture: Provides deep conditioning without greasiness or buildup.

How to Use

Apply the mask to clean, towel-dried hair. Distribute evenly from mid-lengths to ends, focusing on damaged areas. Leave on for 5–10 minutes, then rinse thoroughly. For optimal results, use once or twice a week as part of your regular haircare routine.

Who It Is For

This mask is ideal for anyone with damaged, brittle, or over-processed hair seeking to restore strength and shine. It benefits those experiencing breakage, split ends, or lack of elasticity, and works well for all hair textures including straight, wavy, curly, and coily.

Why Choose This Product

Kérastase is a trusted name in professional haircare, backed by decades of expertise in hair biology. The Resistance Masque Extentioniste harnesses the power of proteins to target the root causes of damage, offering a salon-quality treatment at home. Its lightweight formula delivers visible results without compromising hair's natural movement.
