Kerastase Resistance Masque Extentioniste Length Strengthening Masque 200ml/6.8oz

Experience longer, healthier-looking hair with Kerastase Resistance Masque Extentioniste, a dedicated length-strengthening treatment crafted for slow-growing, damaged lengths. This advanced masque works from root to tip, reinforcing the hair fiber to support steady progress toward stronger, more resilient hair.

• Size: 200 ml / 6.8 oz
• What it is: A length-strengthening hair mask designed to fortify vulnerable lengths that struggle to grow.
• Core ingredients:
  • Creatine — reinforces the hair fiber, boosting internal strength and resilience.
  • Ceramide — supports surface recovery and smooths the cuticle for a uniform finish from roots to ends.
  • Maleic Acid — strengthens and helps seal the cuticle, locking in the treatment’s benefits.
• How it works: Repairs bonds within the hair structure to rebuild strength from within, enhancing overall elasticity and resilience against daily styling stresses.
• The result: Softer, smoother, and more manageable hair that detangles with ease and maintains a uniform coating along the full length.

This masque is uniquely suited for those aiming to extend the length of damaged strands. By focusing on the inner hair structure while smoothing the outer cuticle, Extentioniste helps reduce breakage on lengths that are slow to grow, delivering a cohesive, salon-worthy finish from root to tip.

Who should consider it? Ideal for anyone experiencing fragile, breaking lengths that are slow to grow, and for those who want a disciplined routine to protect and nurture length over time.

Why choose this over ordinary masks? Unlike treatments that only superficially coat the hair, Extentioniste targets bond reinforcement within the fiber, combined with surface recovery to deliver lasting strength, improved elasticity, and easier manageability—so your hair not only looks longer but feels sturdier with daily styling.

Incorporate this targeted masque into your hair care routine to support length maintenance and overall hair health, turning slow-growing lengths into lasting, resilient, and beautifully smooth hair.
