Kérastase Resistance Bain Extentioniste Shampoo - 250 ml

Kérastase Resistance Bain Extentioniste Shampoo - 250 ml revitalizes fragile lengths with a strengthening formula designed for damaged hair.

This 250 ml shampoo is a salon-quality product formulated specifically for women who want to protect and fortify their hair while encouraging healthy growth. The Bain Extentioniste combines Taurine, Ceramide and Creatine to target weakened fibre and improve resilience from root to tip.

The cleansing base features gentle surfactants such as Sodium Laureth Sulfate and Coco-Betaine that remove impurities while delivering smoothing and softening benefits. Additional actives like Polyquaternium-10 and Salicylic Acid help detangle and clarify the scalp to promote a healthier foundation for longer hair.

Using this shampoo provides multiple effects: protection, smoothing, softening and strengthening. It is suitable for all hair colours and is especially effective on damaged hair that needs rebuilding and reduced breakage.

How to use: apply a quarter-size amount to wet hair, massage to lather, rinse thoroughly and avoid excessive friction. For optimal results, finish with Fondant Extentioniste to support length retention and continued strengthening.

The product comes in a practical bottle dispenser and is sold as a single 250 ml unit, making it easy to incorporate into your regular haircare routine. Its fragrance and carefully chosen ingredients ensure a pleasant sensory experience.

Suggested use cases include women recovering from chemical or heat damage, anyone aiming to grow out their hair without sacrificing strength, and those who want a protective daily cleanser that smooths and softens. Kérastase Resistance Bain Extentioniste is ideal for at-home strengthening treatments and as part of a professional haircare regimen.
