Résistance Bain Extentioniste Shampoo by Kérastase

Who It’s For

For weakened, breakage-prone hair looking to grow longer and stronger. Ideal for anyone wanting healthier lengths and resilient ends.

What It Is

A strengthening shampoo that gently cleanses while reinforcing the internal structure of the hair fibre. It targets weak points to reduce breakage, promote length retention, and leave hair smooth, soft, and healthy from root to tip.

Why You’ll Love It

It helps you grow your hair longer without worrying about split ends or breakage. The formula strengthens each strand from within, leaving hair stronger, shinier, and visibly healthier with every wash.

How to Use

Apply to wet hair and massage gently into the scalp and lengths. Rinse thoroughly. Repeat if necessary. Follow with Fondant Extentioniste Conditioner or Masque Extentioniste for best results.

When to Use

Use as your regular shampoo to support stronger, longer, more resilient hair.

Fragrance

A clean, energizing scent with notes of fresh florals and light woods — balanced and refreshing for daily use.
