Why our stylists rate it
From the Partners Hair team
Kérastase Resistance Bain Extentioniste is a length-strengthening shampoo for damaged hair seeking healthy growth. Part of the Kérastase Resistance range. Gentle cleanser that reinforces the hair fibre from within while preventing breakage at the lengths.

Best for: weakened, damaged hair growing through to longer lengths; hair showing breakage, split ends, or slow-looking growth from breakage; the cleansing step in the Extentioniste long-hair routine paired with Fondant Extentioniste, Masque Extentioniste, and Sérum Extentioniste.
Less suited to: severely damaged or chemically over-processed hair primarily needing reconstruction (use Kérastase Resistance Thérapiste — Bain Thérapiste); hair primarily concerned with general damage rather than length retention (use Resistance Force Architecte — Bain Force Architecte); hair primarily concerned with dryness rather than damage (use Kérastase Nutritive); colour-treated hair where colour care is the priority (use Chroma Absolu or Blond Absolu).

Key actives:
- Créatine R Complex — Kérastase's signature length-care technology, combining:
- Creatine — amino acid that reinforces the internal structure of the hair fibre
- Ceramide — lipid that recovers and reseals the cuticle surface
- Taurine — supplementary amino acid with a protective effect on the hair
- Gentle cleansing base — removes impurities without stripping fragile lengths

Benefits:
- Cleanses gently while reinforcing the hair fibre from root to tip
- Helps reduce breakage that prevents hair from reaching longer lengths
- Improves detangling and reduces split-end formation
- Supports healthy-looking growth by protecting the lengths
- Salon-tested Extentioniste programme can reduce split ends by up to 78% and breakage by up to 99% after one application (Kérastase salon service test)

How to use: Apply to wet hair. Massage well to release a rich, airy lather, then rinse thoroughly. Follow with Fondant Extentioniste conditioner. For best results in the full routine, alternate weekly with Masque Extentioniste, prime with Sérum Extentioniste at the scalp, and use Extentioniste Thermique before heat styling.

Format: 250ml shampoo. Also available in 500ml professional/salon size.
