Struggling with hair that breaks before it can grow? The Kérastase Résistance Extensioniste routine is specifically designed for those dreaming of longer, healthier hair. This comprehensive 4-step system works from the scalp to the ends, repairing existing damage while creating optimal conditions for strong, resilient growth.

What’s Included?

  • Bain Extentioniste Shampoo – 250 ml

  • Fondant Extentioniste Conditioner – 200 ml

  • Extentioniste Thermique (Heat Protectant Cream) – 150 ml

  • Sérum Extentioniste (Scalp & Hair Serum) – 50 ml

Perfect If You Have:

  • Hair that snaps or breaks off before it grows long

  • Chemically treated, heat-damaged, or brittle hair

  • Slow growth, limp lengths, or fragile ends

Why You’ll Love It:

  • Strengthens every strand – Creatine R™ and Ceramides reinforce internal structure and smooth the surface.

  • Scalp-to-tip support – Taurine nourishes the scalp, laying the foundation for stronger growth.

  • Seals and shields – The Thermique gel-cream locks in length, smooths splits, and protects against heat up to 230 °C.

  • Growth-friendly – Encourages a healthier environment for long hair with a holistic 4-step system.

Key Ingredients:

  • Creatine R™ – The supercharged combo of creatine + ceramide that reinforces the hair’s inner scaffolding and smooths the surface.

  • Taurine – An amino acid that energizes the scalp and helps create a healthy base for strong hair.

  • Ceramides – Lock in moisture, maintain elasticity, and add shine for resilient lengths.

Pomme Pro Tip:

Use the full 4-step system for best results:

  1. Shampoo with Bain Extentioniste to cleanse and strengthen.

  2. Condition with Fondant Extentioniste for silky, smoother lengths.

  3. Prime with Extensioniste Thermique before heat styling to seal and protect.

  4. Revive your scalp with Serum Extentioniste to stimulate growth and shine.

    1. Cleanse – Start with Bain Extentioniste Shampoo. Apply to wet hair, lather at the roots, then rinse thoroughly and repeat!
    2. Condition – Follow with Fondant Extentioniste Conditioner. Work through mid-lengths to ends (or brush the conditioner through with your Pomme Brush), leave for 2–3 minutes, then rinse.
    3. Strengthen from the Roots – Use Sérum Extentioniste directly on the scalp right after you get out of the shower! Section your hair and apply a few drops, and massage them in. Use 2–3 times per week for best results.
    4. Protect & Style – On towel-dried hair, apply a small amount of Extentioniste Thermique from mid-lengths to ends. Blow-dry (Remember, this product is a heat-activated protector!) or style as usual—this protects against heat up to 230°C.

    1. Is this routine only for long hair?
      Not at all, it's specifically for anyone whose hair resists growing long, regardless of current length. It builds strength and promotes growth from the roots.
    2. How does the serum help?
      The scalp serum infuses ceramides and creatine at the root, fueling a healthy scalp environment that supports stronger, longer hair.
    3. Will heat styling ruin the benefits?
      Nope! The Thermique gel-cream shields your hair up to 230 °C (that’s about 446 °F), helping preserve strength even when you style with heat.
    4. Can fine hair use this without feeling weighed down?
      Yes, just use lighter amounts of each product. The formulas are designed to support length without heaviness.
