Product Overview

The KERASTASE Resistance Extentioniste Thermique Heat Protecting Leave-In Cream is a targeted treatment designed for long, fragile, and damaged hair. Infused with Creastine and Vitamin B6, this leave-in cream works to strengthen the hair fiber, protect against heat styling up to 450°F, and seal split ends to prevent further breakage. Its lightweight, non-greasy formula leaves hair smooth, shiny, and more resistant to daily stressors.

Key Features and Benefits

  • Heat Protection: Provides thermal protection up to 450°F, shielding hair from damage caused by blow-dryers, flat irons, and curling wands.
  • Strengthens Hair: Creastine and Vitamin B6 penetrate the hair cortex to reinforce the fiber, reducing breakage and improving elasticity.
  • Seals Split Ends: The unique formula helps seal split ends, preventing them from traveling up the hair shaft and causing further damage.
  • Lightweight Leave-In Cream: Non-greasy texture that doesn't weigh hair down, making it suitable for fine to medium hair types.
  • Improves Manageability: Detangles and smooths the cuticle, reducing frizz and making hair easier to style.
  • Long-Lasting Results: With regular use, hair becomes visibly stronger, healthier, and more resistant to future damage.

How to Use

Apply a small amount (about a dime-sized drop) to towel-dried or dry hair, focusing on mid-lengths and ends. Do not rinse. For best results, use before heat styling. Can be used daily or as needed. Suitable for all hair types, especially long hair prone to breakage and split ends.

Who It Is For

This product is ideal for individuals with long, fragile, or damaged hair who frequently use heat styling tools. It is also beneficial for those looking to maintain hair length by preventing breakage and split ends. Suitable for all hair types, including color-treated hair.
