K18 LAUNCHES HEATBOUNCE™ -- THE FUTURE OF HEAT PROTECTION

PATENTED RESILICORE™ TECHNOLOGY DELIVERS DEEPER HEAT PROTECTION THAN EVER BEFORE*

SAN FRANCISCO, July 23, 2025 /PRNewswire/ -- K18, the biotech-powered haircare brand that transformed the industry with its category-changing Leave-In Molecular Repair Hair Mask, is once again redefining the future of haircare. Introducing HeatBounce™, a weightless conditioning heat protectant powered by the first of its kind patented ResiliCore™ technology—marking K18's biggest innovation since the launch of the mask's K18PEPTIDE^TM.

At the core of HeatBounce™ is ResiliCore™, K18's newest innovation: a patented heat-shielding technology inspired by resilient proteins found in nature, known for their flexibility and ability to withstand extreme temperatures. Unlike traditional heat protectants that sit on the surface, the size and molecular makeup of ResiliCore™ allow it to penetrate the cortex—where heat damage happens—offering protection up to 450°F (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."

HeatBounce™ transforms from a lightweight cream into a fine mist that delivers conditioning without weight used before any heat tool—whether on damp or dry hair to defend against heat, mechanical damage and UV environmental damage that can cause color fade, dryness, dullness, and breakage.

K18 ambassador and celebrity stylist to SZA, Devante Turnbull, serves as the campaign's lead stylist and ambassador. Known for his visionary work across different textures, colors, and transformative styling, Devante brings the innovation of HeatBounce™ to life, showcasing its ability to protect hair through high-heat styling across diverse hair types. Responsible for SZA's iconic color choices and bouncy curls, Devante embodies the fusion of science and self-expression at the heart of K18.

"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."

With HeatBounce™, K18 delivers on its promise of performance without compromise—empowering stylists and consumers alike to turn on the heat with confidence. It's the essential post-mask, pre-style step that completes the repair and protection routine.

HeatBounce™ launches globally in August 2025.
