Kérastase Genesis Defense Thermique 150ml

When hair feels weakened and prone to breakage from brushing, a considered styling routine can make all the difference. Kérastase Genesis Défense Thermique is a lightweight leave-in blow-dry fluid that helps protect fragile lengths during heat styling while leaving hair feeling smoother and easier to detangle.

Why it belongs in your routine

• Provides heat protection up to 220°C.
• Helps reduce breakage caused by brushing and styling.
• Adds hydration and helps smooth frizz without weighing hair down.
• Supports easier detangling before you reach for your brush or dryer.

How to use

Work through clean, towel-dried lengths and ends before blow-drying. Comb through to distribute evenly, then style as usual. Follow the product label for directions and precautions; avoid contact with eyes and rinse thoroughly if contact occurs.

For a more complete Genesis routine, pair with the shampoo and conditioner selected for your hair and scalp needs.
