1. What does the Kérastase Extentioniste Trio Bundle do for my hair?
This bundle strengthens weak, damaged strands, reduces breakage, and protects against heat and daily stressors. It helps you grow longer, healthier-looking hair without compromising strength.
2. Is the Extentioniste range good for all hair types?
Yes! While it’s especially effective for brittle, damaged, or slow-growing hair, the Extentioniste range can be used on all hair types—from fine to thick—to improve resilience and length retention.
3. How often should I use the Masque Extentioniste?
We recommend using the mask 1–2 times per week in place of your regular conditioner for deep repair and nourishment. For extra strength, pair with the shampoo and thermique every wash day.
4. Does Extentioniste really help hair grow faster?
Kérastase Extentioniste doesn’t change your natural hair growth speed, but it does strengthen strands from root to tip, preventing breakage and split ends. This means you’ll finally keep the length you grow!
5. Can I use Extentioniste Thermique without heat styling?
Yes! While Thermique is a heat protectant, it also strengthens and smooths hair when air-drying. It’s a great leave-in treatment whether you style with tools or go heat-free.
6. Is this bundle safe for colour-treated or chemically processed hair?
Absolutely. The Extentioniste formulas are designed to rebuild and fortify fragile hair, making them ideal for colour-treated, bleached, or chemically processed strands that need extra care.
