K18 heat bounce

The Future of Heat Protection

This leave-in conditioning heat protectant detangles, softens, and shields hair with advanced heat protection — reducing breakage by up to 85% after blow-drying.

• Protects hair from heat (up to 232°C)
  
• 85% less breakage after blow-drying*
  
• Lightweight conditioning for softer, smoother, tangle-free hair

*Heat protection observed on hair in clinical testing after application of HeatBounce and use of 450℉ (232℃) flat iron on dry hair.
