A balm-in-shampoo that repairs over-processed hair as it washes
Kérastase Résistance Bain Thérapiste is a balm-in-shampoo for very damaged, over-processed hair that feels rough and brittle. Its dense, regenerating texture wraps each fiber during washing to limit friction, so hair is cleansed gently yet effectively. The Fibra-Kap complex, made of SP-94, six amino acids and a hydrolyzed wheat protein, helps reactivate the hair's keratin-associated proteins, while Resurrection Plant sap brings a strong repair boost. Hair comes out shinier, smoother and healthier-looking.
The texture
A rich, creamy balm rather than a runny shampoo. You work it into the lengths first with a little water; it gives a low, creamy lather and rinses away to leave hair smooth and easier to detangle.
Who it suits
- Hair damaged by bleaching, colouring or chemical straightening
- Very dry, rough and brittle lengths
- Hair that breaks easily when brushed
- Anyone following with a mask or leave-in care
Worth knowing before you buy: it contains sodium laureth sulfate, silicones and fragrance. Fine hair may find it heavy, so focus it on the lengths.
How long a bottle lasts
Used two to three times a week, the 250ml bottle lasts around two months.
