Description:
- Kérastase Resistance Fondant Extentioniste is a strengthening, length-boosting conditioner designed to help fragile, breakage-prone hair grow longer, stronger, and smoother from root to tip. This lightweight yet creamy fondant formula envelops each strand, detangling instantly while reinforcing the hair fiber for a silky, flowing finish. Ideal for those aiming for longer hair without compromising on strength, shine, or softness, it delivers a luxurious salon-like experience at home with a fresh, elegant fragrance.
Indications:
- Designed for weakened, breakage-prone hair that struggles to grow past a certain length
- Ideal for hair damaged by heat styling, brushing, or chemical treatments
- Perfect for dull, lifeless hair lacking resilience, smoothness, and shine
- Suitable for hair with split ends and surface damage along the lengths
Key Benefits:
- Strengthens the hair fiber from lengths to ends to reduce breakage
- Improves hair elasticity and resilience, helping hair grow longer and healthier-looking
- Detangles instantly, minimizing mechanical damage from brushing and styling

Specialty:

- Enriched with strengthening and fortifying complexes to protect lengths and ends
- Free from heavy, greasy residue to keep hair light and bouncy

Key Ingredients:
- Ceramides – Help reinforce the hair fiber, improve cohesion of the cuticle, and enhance resistance to breakage
- Creatine – Known to support hair fiber strength and structure, helping to fortify weakened lengths
- Maleic Acid – Helps to smooth and condition the hair surface, promoting a uniform, glossy finish along the lengths
Note: Exact concentrations of these ingredients are not provided by the manufacturer and are therefore unavailable.
Texture & Finish:
- Creamy, lightweight fondant texture that glides easily through the hair
- Rinses cleanly without weighing hair down, leaving a soft, fluid movement
- Leaves hair with a smooth, shiny, and healthy-looking finish and a fresh, refined fragrance
How to Use:
- Shampoo hair first, ideally with a strengthening or length-boosting shampoo such as Kérastase Resistance Bain Extentioniste.
- On towel-dried hair, apply a small amount of Fondant Extentioniste to mid-lengths and ends, avoiding the roots.
- Distribute evenly using fingers or a wide-tooth comb, gently massaging through the lengths.
- Leave on for 2–3 minutes to allow the formula to penetrate and condition the hair fiber, then rinse thoroughly with lukewarm water. Use in the morning or evening as part of your regular hair-wash routine, as often as you shampoo.
- Follow with your preferred leave-in treatment or heat protectant before styling to further protect lengths and ends and support your long-hair care routine.
