K18's new HeatBounce launch is a weightless conditioning heat protectant featuring the brand's ResiliCore heat-shielding technology, which is inspired by resilient proteins found in nature.
The launch timing is aligned with the direction of the market. In Q1 2025, hair care was a top grower in the prestige space, per Circana, increasing sales by 4%. Among the top performers were heat protection offerings.
Deep Hair Protection with ResiliCore and HeatBounce Launching August 2025
ResiliCore penetrates the hair cortex, where heat damage occurs, offering protection from temperatures up to 450°F (232°C), per K18. Unlike traditional heat protectants that sit on the surface, ResiliCore reportedly provides deep defense, reducing breakage by 85% during blow drying.
HeatBounce is designed for use on damp or dry hair and protects against heat, mechanical damage and UV exposure. Its lightweight cream-to-mist formula ensures conditioning without added weight, making it suitable for all hair types.
The product will be available globally in August 2025.
Intelligent Heat Protection for Healthy Hair
"HeatBounce reflects our commitment to pushing the boundaries of hair science," said Suveen Sahib, co-founder and CEO of K18. "Powered by our patented ResiliCore technology, it delivers intelligent heat protection that penetrates deep into the hair fiber—reinforcing inner bonds and preserving strength by dynamically responding to heat. It's a true breakthrough and the perfect complement to our molecular repair innovation."
"As a stylist, I need products that protect without compromising style—and HeatBounce delivers on every front," said Devante Turnbull, K18 ambassador and celebrity stylist to SZA. "Whether I'm creating high-gloss waves, diffusing natural curls or protecting SZA's hair on her global tour, I know I'm shielding the hair from heat, mechanical, and UV damage while keeping it soft, shiny, and full of life. It's a total game-changer for styling healthy hair across every texture."
