KERASTASE Résistance Bain Thérapiste Shampoo 250ml

KERASTASE Résistance Bain Thérapiste Shampoo 250ml is an intensive repairing shampoo with a unique jelly-like texture, specifically developed for very damaged, over-processed and highly sensitised hair.

Powered by Kérastase's FIBRA-KAP™ technology, the formula helps repair weakened hair fibres and reinforce their internal structure while cleansing. It envelops damaged strands to reduce friction during washing, helping improve strength, smoothness and the appearance of brittle, damaged lengths.

Unlike a standard shampoo for dry hair, Bain Thérapiste is designed for hair experiencing advanced structural damage, particularly from repeated chemical or mechanical stress.

Cleanse → Repair → Reinforce → Reduce Friction → Smooth → Protect

What Is It?

Bain Thérapiste is the cleansing step of the KERASTASE Résistance Thérapiste routine.

Its unusual gel-like texture is designed to envelop damaged hair during washing and reduce friction between weakened fibres. Kérastase describes it as repairing the hair fibre during the wash, rather than functioning only as a conventional cleanser.

The key distinction is the level of damage.

KERASTASE positions:

Force Architecte → Damaged hair / erosion levels 1–2

Thérapiste → Very damaged and over-processed hair / erosion levels 3–4

So for Peggymou, the customer message should be simple:

Damaged hair → Force Architecte

Very damaged or over-processed hair → Thérapiste
