KÉRASTASE Resistance Therapiste Hair Mask 6.8 fl oz — Repairing, Strengthening Treatment for Damaged Hair

KÉRASTASE Resistance Therapiste Hair Mask is an intensive strengthening and repairing cream formulated to rebuild extremely damaged, over-processed hair for smoother, more resilient strands.

This deep-treatment mask combines protein-rich ingredients and native plant cells to fortify weakened fiber, restore surface softness, and reduce the look and feel of breakage. Designed for hair that has been chemically treated, heat-styled, or otherwise stressed, the formula works by penetrating the strand to reinforce structure while adding moisture and shine without weighing hair down.

How does this mask repair very damaged and overstressed hair?

The mask uses a concentrated repairing complex to rebuild compromised fiber from mid-lengths to ends. Its conditioning texture penetrates the cortex to restore tensile strength and improve elasticity so strands break less under tension.

• Wheat protein helps fill and reinforce weakened areas of the hair shaft.
• Native plant cells support fiber resilience and surface smoothness.
• Rich, yet light-penetrating cream ensures nourishment without heavy residue.

What results can I expect after using it?

With regular application, hair feels softer, looks glossier, and handles better during styling. The formula aims to reduce visible split ends and breakage while restoring a more uniform texture.

• Smoother surface for enhanced shine and easier detangling.
• Improved strength that helps prevent future breakage from styling.
• Revitalized touch and appearance after a single treatment.

How do I use the Resistance Therapiste Hair Mask for best results?

Apply to freshly washed, towel-dried hair focusing on mid-lengths and ends; a quarter-size amount is usually enough for medium-length hair. Massage gently to work the cream strand-by-strand, leave it on for 5–10 minutes, then rinse thoroughly.

• Use after shampooing with a Resistance shampoo for optimal reinforcement.
• Can be used daily or as a weekly intensive treatment depending on damage level.
• Pair with the Resistance Extentioniste Conditioner for a complete repair routine.

Will this weigh down fine hair or suit thick, coarse textures?

The formulation is designed to deliver deep repair without excessive weight; however, application amount should be adjusted by hair type. Fine or low-porosity hair benefits from sparing use on ends, while thicker or more porous hair can tolerate more generous application for intensive reconstruction.

• Fine hair: use a smaller amount and avoid the roots to prevent flattening.
• Medium to thick hair: apply more evenly from mid-lengths to ends for full coverage.
• Very damaged hair: leave on the recommended 5–10 minutes, or extend slightly for added intensity.

Who is this for: KÉRASTASE Resistance Therapiste Hair Mask is suited to anyone with very damaged, chemically processed, heat-stressed, or brittle hair seeking a salon-grade repairing treatment. It’s ideal for people wanting to rebuild strength, reduce breakage, and restore softness and sheen — whether you color, relax, or frequently heat-style your hair.
