Style with Heat. Protect with Confidence.

Every time you reach for a flat iron or curling wand, you're exposing your hair to damage. The Kérastase Genesis Defense Thermique Heat Protective Spray creates an invisible shield between your hair and high heat — while simultaneously fighting hair fall and strengthening roots from within.

Part of the iconic Kérastase Genesis range, this spray is engineered for those who refuse to choose between beautiful styling and healthy hair.

Key Benefits

• Heat protection — forms a barrier against styling tool damage, preserving hair's integrity and vibrancy
• Anti-hair loss — helps reduce hair fall and fortifies weakened roots with each use
• Strengthening — reinforces hair structure for more resilient, breakage-resistant strands
• Daily use formula — lightweight enough to integrate seamlessly into your everyday routine
• Professional-grade — trusted Kérastase Genesis technology used by salon professionals worldwide

How to Use

Apply to damp or dry hair before heat styling. Hold 6–8 inches from hair and spray evenly through lengths and ends. Style as usual with your flat iron, curling wand, or blow dryer.
