Kérastase Résistance Bain Extentioniste

Kérastase Résistance Bain Extentioniste – Length-Strengthening Shampoo for Growing Hair

Available in Canada at Curious Salons

For
Fragile, breakage-prone, or slow-growing hair needing strength, smoothness, and a healthier foundation for longer lengths.

Description
A strengthening start for your length-loving journey. Kérastase Résistance Bain Extentioniste is a fortifying shampoo designed to gently cleanse while reinforcing the hair fibre from root to tip. Its creamy, invigorating lather improves elasticity, reduces breakage, and supports a stronger, more resilient foundation — helping hair grow longer, smoother, and healthier over time.

Formulated with the advanced Creatine R™ Complex and Taurine, this shampoo strengthens fragile fibres, energizes the scalp environment, and protects the lengths as they grow. Perfect for anyone looking to achieve longer hair — especially in Canada’s breakage-prone seasonal climates — it leaves hair soft, supple, and beautifully fortified.
