Kérastase Resistance Fondant Extentioniste - 200ml is a professional-quality conditioner meticulously crafted for brittle and break-prone hair. With the power of ceramides, this salon-grade treatment repairs, strengthens, and restores resilience, leaving your hair silky, manageable, and primed for natural growth without breakage.

Key Benefits and Features
  • Hydration: Deeply nourishes each strand, locking in moisture and reducing brittleness for prolonged softness.
  • Strength: Fortifies the hair shaft from within, resisting snap and split ends, and supporting healthier, longer lengths.
  • Repair: Utilizes ceramides to target damaged fibers, restoring elasticity and resilience, even after chemical treatments or heat styling.
  • Detangling & Shine: Enhances slip for easy brushing, imparting a natural, subtle gloss without leaving heavy residue.
  • Protective Seal: Forms a shield on the cuticle, guarding against daily styling stress and environmental damage.
Who It’s For

Ideal for chemically treated or heat-damaged hair, this conditioner is perfect for anyone seeking smoother, more manageable lengths. Suitable for color-treated hair, it works well across different hair types; adjust the amount used based on hair thickness to avoid weighing down finer hair.

Key Ingredients
  • Ceramide R: Deeply repairs the hair cuticle, restoring structural integrity and boosting resilience.
  • Pro-Keratin: Rebuilds and strengthens damaged bonds to improve overall texture and manageability.
  • Glycerin: Moisture-locking humectant that keeps strands soft and supple.
How to Use
  • After shampooing, remove excess water and apply Fondant Extentioniste from mid-lengths to ends, avoiding the scalp.
  • Allow the conditioner to penetrate by leaving it on for 1–3 minutes.
  • Rinse thoroughly and style as usual.
  • For best results, use the full Resistance line, including shampoo and serum, to maximize repair and growth support.

Why our stylists rate it
From the Partners Hair team
Kérastase Resistance Fondant Extentioniste is a length-strengthening conditioner for damaged hair seeking healthy growth. Part of the Kérastase Resistance range. Daily-use conditioner that detangles, seals split ends, and reinforces the hair fibre at the lengths and ends.

Best for: weakened, damaged hair growing through to longer lengths; hair prone to tangling, breakage, or split ends; daily conditioning in the Extentioniste long-hair routine paired with Bain Extentioniste shampoo and Masque Extentioniste weekly treatment.
Less suited to: severely damaged hair needing deeper reconstruction (use Resistance Ciment Anti-Usure for daily anti-breakage care or Resistance Thérapiste range for the most damaged hair); fine, dry hair primarily seeking lightweight hydration (use Nutritive Lait Vital); colour-treated blonde hair (use Blond Absolu Cicaflash); curly hair seeking definition (use Curl Manifesto Fondant Conditioner).

Key actives:
- Créatine R Complex — Creatine + Ceramide; reinforces the internal hair fibre structure and reseals the cuticle
- Glycerin — humectant that supports moisture retention through the lengths
- Conditioning emollients — smooth and detangle without weighing fragile lengths down
- Cetearyl Alcohol — fatty alcohol that softens and conditions the hair shaft

Benefits:
- Reinforces the hair fibre at the lengths and ends where breakage occurs
- Seals split ends and helps reduce further splitting between wash days
- Detangles gently from mid-lengths to tips, reducing breakage during combing
- Smooths and softens damaged lengths without weight
- Supports the lengthening process when used consistently with the full Extentioniste routine

How to use: After shampooing with Bain Extentioniste, apply to the lengths and ends of towel-dried hair. Detangle gently with a wide-tooth comb, working from the bottom up to avoid stressing the fibre. Leave on for 1–2 minutes, then rinse thoroughly. Use after every wash. For deeper repair, alternate weekly with Masque Extentioniste.

Format: 200ml conditioner. Also available in 1000ml professional/salon size.
