Dreaming of mermaid lengths without the breakage? This powerhouse Kérastase Extentioniste trio strengthens every strand from the inside out, defends against daily damage, and helps your hair finally push past its breaking point—literally.

What’s Included?

  • Bain Extentioniste Shampoo (250ml) – A strengthening shampoo that gently cleanses while targeting weak, breakage-prone areas to kick-start healthier growth.

  • Masque Extentioniste (200ml) – An intensive repairing mask that nourishes, fortifies, and smooths the fibre for stronger, more resilient lengths.

  • Extentioniste Thermique (150ml) – A leave-in heat protectant that seals the cuticle, prevents split ends, and shields hair from heat styling up to 230°C.

Perfect If You Have:

  • Hair that struggles to grow past a certain length

  • Breakage, split ends, or thinning mid-lengths

  • Chemically treated or heat-damaged strands

Why You’ll Love It:

  • Boosts growth potential – Gently cleanses and nourishes while reinforcing weak areas of the fibre.

  • Repairs & strengthens – Deep treatment mask rebuilds internal structure and seals split ends for long-lasting resilience.

  • Shields against heat & breakage – Leave-in primer protects up to 230°C, smooths frizz, and keeps strands strong through styling.

Key Ingredients:

  • Creatine R Complex – Strengthens from within to reinforce elasticity and structure.

  • Ceramides – Smooth and fortify the cuticle for healthier, shinier hair.

  • Taurine – Protects the scalp environment and supports optimal growth.

Pomme Pro Tip:
For the best results, use the full routine together: cleanse with Bain Extentioniste, nourish deeply with Masque Extentioniste, and finish with Extentioniste Thermique before styling. Consistency is key—stick with it and watch your hair grow stronger, longer, and healthier.w

  • 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.
