Kerastase Resistance Masque Therapiste is a revolutionary fiber quality renewal masque designed for very damaged, over-processed thick hair. This intensive treatment targets the hair core, helping strands regain strength and elasticity while unveiling smoother, revitalized looks.

Powered by FIBRA-KAPTM technology to compensate for missing KAPs and reactivate their synthesis, it blends six amino acids to repair damaged areas and a wheat protein redivative to restore uniformity across the fiber. The luxurious, buttery texture melts into hair, sealing in moisture and supporting fibers that have endured heavy erosion (erosion level 3–4).

• FIBRA-KAP technology: replenishes keratin-associated proteins for stronger, more resilient strands
• Six amino acids: targeted repair where damage is deepest
• Wheat protein redivative: restores uniformity and smoothness across the hair
• Buttery texture: decadent, fast-penetrating nourishment without weighing thick hair down
• Elasticity & strength: visibly renewed hair that feels reboundingly flexible

Ideal for very damaged, over-processed thick hair, this masque delivers a tangible transformation—from frayed to fortified and visibly healthier-looking hair. Take the first step toward resilient, revitalized locks with Kerastase Resistance Masque Therapiste today.
