KÉRASTASE Resistance Bain Therapiste restorative shampoo for damaged hair, 8.5 fl oz — strengthens & hydrates

KÉRASTASE Resistance Bain Therapiste is a restorative shampoo that repairs severely damaged hair, strengthens weakened fibers, and hydrates lengths to reduce breakage.

This salon-grade cleansing treatment targets hair weakened by heat styling, chemical services, and mechanical stress. Formulated with KÉRASTASE’s Fibra-Kap-inspired technology, the shampoo works to rebuild internal fiber structure, smooth rough cuticles, and improve elasticity so strands look healthier and feel more resilient after repeated use.

How does this shampoo rebuild badly damaged hair?

The formula delivers reconstructing ingredients that penetrate the hair fiber to reinforce internal structure and seal damaged zones. Regular use helps restore flexibility and reduces snapping during brushing and styling without weighing hair down.

• Fibra-Kap-style complex that targets weakened points along the fiber
• Hydrating agents to replenish moisture lost from heat and chemical exposure
• Gentle surfactants that clean without stripping restorative actives

What results can I expect after using Bain Therapiste?

After washing, hair should feel softer, appear smoother, and show fewer split ends or breakage signs over time. The shampoo prepares strands for follow-up treatments like masks or serums, improving overall manageability and shine.

• Noticeably softer texture and improved combability
• Reduced friction and fewer visible breaks along the lengths
• Enhanced readiness for conditioning and sealing products

How do I use it for best repair results?

Apply to wet hair and work into a light lather, focusing on mid-lengths and ends where damage concentrates. Repeat the wash, leave on for two minutes during the second application, then rinse thoroughly and follow with a mask or serum for deeper reconstruction.

• Use a coin-sized amount on first wash, repeat for thorough treatment
• Leave the second application in for 2 minutes before rinsing
• Pair with Therapiste Hair Mask and Serum for complete fiber renewal

Who this is for: KÉRASTASE Resistance Bain Therapiste is created for very damaged, over-processed, or fragile hair that needs active reconstruction. If your hair snaps when brushed, shows split ends, or lacks elasticity after thermal or chemical styling, this shampoo helps restore strength and moisture as part of a targeted repair routine.
