Meet the next generation of heat protection with K18 HeatBounce. This innovative leave-in conditioning spray detangles, softens, and delivers deeper protection than ever before—helping to prevent up to 85% less breakage after blow drying.

Powered by resilicore™ heat-shielding technology, inspired by proteins in nature that withstand extreme heat, HeatBounce penetrates deep into the hair’s inner cortex—where damage really happens. Unlike traditional heat protectants that only coat the cuticle, resilicore™ forms a protective shield from within, fortifying strands against high-heat styling.

The conditioning blend instantly hydrates and smooths, leaving hair soft, tangle-free, and more manageable—even if it’s damaged. Designed for all hair types and textures, and safe to use on extensions, HeatBounce is your essential styling partner for blow-drying, straightening, or curling.
