Kerastase Resistance Bain Therapiste Balm-In-Shampoo Fiber Quality Renewal Care (For Very Damaged, Over-Processed Hair) 250ml/8.5oz

Discover Kerastase Resistance Bain Therapiste Balm-In-Shampoo, a renewing cleanser crafted for very damaged, over-processed hair. Its jelly-like texture cleanses while actively repairing the fiber, delivering strength, smoothness, and a healthy glow from the very first wash.

Powered by FIBRA-KAPTM technology, this balm-in-shampoo compensates for missing KAPs and reactivates their synthesis along the hair fiber. Six targeted amino acids focus on the most damaged areas, while a wheat protein derivative helps restore uniformity across the strand. The result is a renewed fiber that stands up to future styling stress and chemical exposure.

• Repairs hair fiber during cleansing so your wash becomes a renewal ritual
• Strengthens from within, reducing breakage and improving resilience
• Envelops brittle strands to renew split ends and boost elasticity
• Leaves hair smoother, shinier, hydrated, and visibly revitalized
• Ideal for very damaged, over-processed thick hair (erosion level 3–4)

With regular use, expect strands that feel sturdier and more manageable, a noticeable reduction in breakage, and a luminous, healthy-looking finish that restores vitality to dull, damaged hair.

Who is this for?

Designed specifically for very damaged, over-processed thick hair where the fiber has eroded. If your hair has struggled with color processing, heat styling, or persistent chemical treatments, Bain Therapiste renews and rebuilds from the inside out—delivering stronger, more resilient strands.

How to use

1. Apply to wet hair and massage from scalp to ends, focusing on mid-lengths where damage is greatest.
2. Rinse thoroughly to remove product and residue.
3. For enhanced renewal, follow with a conditioner or treatment from Kerastase Resistance to seal in reconstruction.

Size: 250 ml (8.5 oz). Experience thicker-feeling, smoother, and more hydrated hair with a healthy, revitalized sheen that makes very damaged hair look renewed.
