Powered by patented ResiliCore™ technology, protecting hair as deep as heat damage goes.

K18, the biotech-powered brand that redefined hair repair, has unveiled its most groundbreaking launch since the cult-favorite K18PEPTIDE™ Mask.
Meet HeatBounce™, a weightless conditioning heat protectant powered by ResiliCore™, a patented heatshielding technology inspired by resilient proteins found in nature. HeatBounce™ protects deeper than any other heat protectant, protects hair up to 230 degrees Celsius and results in 87% less breakage after drying.

At the core of HeatBounce™ is ResiliCore™, K18’s newest innovation: “a patented heatshielding technology inspired by resilient proteins found in nature, known for their flexibility and ability to withstand extreme temperatures.” Unlike traditional protectants that sit on the surface, ResiliCore™ penetrates the cortex—“where heat damage happens- offering protection up to 232°C* and reducing breakage by 85% when blow drying*.”

“HeatBounce™ reflects our commitment to pushing the boundaries of hair science,” said Suveen Sahib, Co-founder & 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.”

K18 ambassador and celebrity stylist Devante Turnbull, best known for his work with SZA, fronts the campaign. “As a stylist, I need products that protect without compromising style- and HeatBounce™ delivers on every front,” Turnbull said. “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.”

HeatBounce™ launches globally September 1st 2025.
