Résistance Fondant Extentioniste

Effortless detangling for precious lengths. Kérastase Résistance Fondant Extentioniste is a creamy, lightweight strengthening conditioner for long hair with damaged lengths. Creatine R and maleic acid reinforce the fibre and seal the cuticle, so hair detangles easily and split ends are sealed. 200 ml. A Curious stylist favourite.

Key Ingredients, Explained

• Creatine R: An exclusive complex of creatine, an amino acid that reinforces the hair's internal structure, and ceramide, which helps recover the hair surface.
• Maleic acid: Very small particles that penetrate the fibre to reinforce it and seal the cuticle with a uniform coating from roots to ends.

What It Does

• Strengthens damaged lengths.
• Seals the cuticle to protect hair from root to tip.
• Detangles easily.
• Nourishes and seals split ends.

Why We Love It

• Easy comb-through for long hair.
• Lightweight, no heavy residue.
• Pairs with Bain Extentioniste.

Best For

How to Use

2. Leave in for 2 to 3 minutes.
3. Rinse thoroughly.

Curious Stylist Tip

Detangle with a wide-tooth comb while the conditioner is still in, starting at the ends and working up. You get less breakage than brushing after rinsing.
