KÉRASTASE Resistance Therapiste Hair Mask Repairing Cream 6.8 fl oz — Strengthens & Deeply Nourishes

KÉRASTASE Resistance Therapiste Hair Mask is an intensive repairing cream that rebuilds very damaged, over-processed hair to reduce breakage and restore softness and shine.

Designed for hair weakened by chemical services, heat styling and mechanical stress, this rich mask targets compromised fibers to reinforce strength, hydrate and smooth the surface. Its concentrated formula works strand by strand to replenish structure and flexibility so hair feels more resilient and looks healthier. Regular use helps protect against future breakage while improving manageability and shine.

How does this mask repair over-processed hair?

The Therapiste mask combines strengthening actives with hydrating agents that penetrate the fiber to rebuild and fortify internally while smoothing externally. It focuses on reconstructing the hair’s internal network so strands resist stretching and snapping.

• Wheat protein delivers structural reinforcement to weakened cortex fibers.
• Native plant cells support fiber flexibility to prevent rigid breakage.
• Rich emollients hydrate cuticles for a smoother, shinier surface.

When and how should I use the mask for best results?

Use the mask on wet, shampooed hair after cleansing to allow ingredients to fully absorb into the fiber. Apply from mid-length to ends, massage gently through the strands, leave on for 5–10 minutes, then rinse thoroughly.

• Apply a quarter-size amount for medium lengths; adjust by hair thickness and length.
• Can be used daily or a few times per week depending on damage level.
• For a full regimen, pair with Resistance Extentioniste Shampoo and Conditioner.

Will this product protect my hair from future breakage?

While no product can guarantee zero breakage, the mask strengthens hair fibers and improves flexibility to reduce the risk of snapping from styling and mechanical stress. Reinforcing the hair’s core and smoothing the cuticle helps hair better withstand daily wear and heat tools.

• Rebuilds internal fiber structure to resist tensile stress.
• Hydrates and seals cuticles to minimize friction and tangling.
• Regular use supports longer, healthier-looking lengths by preventing loss from breakage.

How will my hair look and feel after using Therapiste?

After treatment, hair is noticeably softer to the touch, easier to detangle and reflects more light for enhanced shine. Over several uses, hair texture improves as fibers regain structure and manageability increases.

• Smoother surface reduces frizz and improves slip for styling.
• Restored elasticity gives hair a less brittle, more resilient feel.
• Enhanced shine and polish make color and cut appear healthier.

Who is this for: KÉRASTASE Resistance Therapiste Hair Mask is formulated for people with very damaged, over-processed, chemically treated or heat-weakened hair seeking an intensive reconstructing treatment. It benefits short or long lengths that need structural repair, increased flexibility and ongoing protection against breakage. If you want a concentrated mask to rebuild fiber integrity while restoring softness and shine, Therapiste is a targeted option to add to a strengthening haircare routine.
