Kérastase Resistance Ciment Thermique: Strengthening Heat Protector 150ml

Kérastase Resistance Ciment Thermique is a strengthening heat-protective leave-in milk designed for weakened, damaged or breakage-prone hair. Activated by heat, the lightweight cream works to smooth the hair fibre and provide a protective top coat along the lengths, helping to reduce the look of split ends and surface damage while adding softness and shine. Powered by Vita-Ciment® and thermo-seal technology, it supports the feel of stronger hair and helps to protect against heat styling up to 180°C, making blow-drying feel quicker and easier.

Ideal for hair that’s frequently styled with dryers or hot tools, this product fits seamlessly into a strengthening haircare routine after shampoo and conditioner. Applied to clean, towel-dried hair, it helps to prepare strands for styling while leaving them feeling smoother and more manageable. The silky texture distributes easily through mid-lengths and ends without weighing hair down, making it a practical everyday choice for those wanting hair that feels more resilient, polished and cared for.

How to use
How to Use:
After shampooing and conditioning, gently towel-dry hair. Work a pea- to walnut-sized amount of product between your hands, then apply evenly through the mid-lengths and ends. Detangle if needed and do not rinse. Blow-dry and, if desired, follow with heat-styling tools.

Frequency:
Use after each wash or whenever you heat-style your hair, according to the product instructions.

Application Technique:
Apply to clean, towel-dried hair before using a hairdryer or other heated tools. Focus on the most fragile areas, such as mid-lengths and ends, and distribute the product evenly using your fingers or a wide-tooth comb.

Best Practices:
For best cosmetic results, avoid applying directly to the roots to help maintain lightness. Use the product as the final step in your wash routine before styling. Adjust the amount used according to hair length and thickness, and allow the product to remain in the hair to support heat protection and smoothness.

Safety Tips:
Use externally only. Avoid contact with eyes; if this occurs, rinse thoroughly with water. Discontinue use if irritation occurs and keep out of reach of children. Always follow any additional guidance on the packaging.
