Résistance Thermique Extentioniste by Kerastase

Résistance Thermique Extentioniste by Kérastase

Who It’s For

For weakened or breakage-prone hair that’s growing out or exposed to frequent heat styling. Ideal for anyone looking to protect lengths and ends while encouraging stronger, longer hair growth.

What It Is

A leave-in heat-protectant cream that strengthens and smooths hair while protecting it from heat damage up to 230°C. It fortifies the fibre, seals split ends, and prevents breakage to help maintain healthy, resilient lengths.

Why You’ll Love It

It makes growing long, strong hair easier by reducing breakage and split ends. Hair feels smoother, softer, and more resistant to heat and daily stress — healthy from root to tip.

How to Use

Apply to towel-dried hair before blow-drying or heat styling. Focus on mid-lengths and ends. Do not rinse. Use regularly for best results.

When to Use

Use before any heat styling or as a daily strengthening primer for fragile hair.

Fragrance

A fresh, clean scent with soft floral and light woody notes — balanced and subtle for everyday wear.

Key Ingredients
