Kerastase Resistance Masque Therapiste Fiber Quality Renewal Masque - (16.9 oz) The ultimate deep repair masque for your hair's second life

If your hair is waving the white flag after years of coloring, heat styling, or just general wear-and-tear, it's time to call in the cavalry. The Kérastase Resistance Masque Thérapiste is a heroic, fiber-renewing treatment crafted specifically for the unique challenge of severely damaged, over-processed, and brittle hair with an "erosion level" of 3-4. This luxurious mask doesn't just coat the hair; its rich, buttery texture dives deep into the hair fiber's core, delivering a powerful 'bandage' effect. It’s a sensory feast that manages to feel simultaneously intensive and weightless, turning a dire damage repair session into a deeply restorative and pampering experience.

The real breakthrough here is the integration of the brand's proprietary FIBRA-KAP™ complex and the legendary Resurrection Sap. Think of KAPs (Keratin Associated Proteins) as the vital internal cement that holds your hair's structure together—when hair is extremely damaged, these KAPs are lost. The Masque Thérapiste is engineered to compensate for those missing KAPs and actively reactivate their synthesis, essentially rebuilding the hair from the inside out. The potent Resurrection Sap, extracted from a plant known for its astonishing ability to come back to life after near-total desiccation, contributes its regenerative power to the hair fiber, giving your strands a fighting chance to regain their resilience and elasticity.

Using this masque is the moment you commit to truly renewing your hair’s strength and vitality. After just one application, you’ll feel the palpable difference—the rough, frayed ends begin to smooth, and the overall fiber regains a toned, supple, and silky softness. This is the intensive, professional-grade treatment that restores uniformity and shine, revealing hair that looks and feels profoundly healthier and more manageable. It’s the ultimate weekly ritual for fortifying against future breakage, transforming hair that was once on the verge of breaking into a gorgeous cascade that is full of life, movement, and strength.
