KÉRASTASE Resistance Bain Thérapiste strengthening shampoo for damaged hair — 250ml rebuilding, reduces breakage

KÉRASTASE Resistance Bain Thérapiste is a restorative strengthening shampoo formulated to rebuild severely damaged, brittle hair while improving elasticity and reducing breakage.

Designed for overstressed and weakened lengths, this salon-grade cleanser targets fiber damage from heat, styling and mechanical stress. It gently removes impurities while delivering active rebuilding ingredients that help seal and reinforce the hair structure for a smoother, more resilient finish.

How does this shampoo repair heavily damaged hair?

The formula contains a fiber-rebuilding complex that penetrates weakened strands to restore internal cohesion and mend split ends. Regular use helps reduce the appearance of fraying and increases strand resistance to snapping under tension.

• Fibra-Kap inspired technology to rebuild the inner hair matrix
• Seals and smooths damaged fiber cuticles for a sleeker surface
• Targets lengths and ends where stress and breakage concentrate

Will it cleanse without stripping moisture or softness?

Yes — the cleansing agents are selected to remove buildup while maintaining hydration and slip, so hair remains manageable after washing. The shampoo leaves hair feeling softer, not dry, by balancing cleansing with conditioning actives.

• Gentle surfactant system that lifts impurities without harsh stripping
• Hydrating components to preserve softness and ease detangling
• Reduces surface friction to minimize additional mechanical damage

How should I use it to get the best rebuilding effect?

Work a small, coin-sized amount through wet hair, lathering from roots to ends, and rinse. For deeper repair, repeat the wash, focusing the second application on lengths and ends, leave on for two minutes, then rinse thoroughly.

• Apply to soaking wet hair; distribute evenly by massaging
• Second application concentrates on mid-lengths and tips for targeted repair
• Two-minute dwell time allows rebuilding ingredients to act before rinsing

Should I combine it with other products for stronger results?

Pairing the shampoo with the matching Therapiste hair mask and serum from the Resistance collection accelerates fiber reconstruction and adds long-lasting radiance and silkiness. Using the three together creates a complete routine that reconstructs, protects and restores tactile softness.

• Therapiste mask restores deeper internal strength and shine
• Therapiste serum seals ends and provides targeted reinforcement
• Consistent trio use reactivates hair radiance and smooth touch

Who is this for? KÉRASTASE Resistance Bain Thérapiste is crafted for people with extremely weakened, overstressed, or brittle hair who want a salon-quality rebuilding cleanser. It’s ideal for anyone who regularly uses heat tools, chemical services, or suffers from mechanical breakage and needs a focused regimen to reduce snap, repair split ends and restore a softer, more resilient strand feel.
