K18 HeatBounce Conditioning Heat Protectant - 118ml

K18 HeatBounce Conditioning Heat Protectant is a breakthrough leave-in formula that goes beyond traditional heat protection—guarding hair from the cuticle all the way to the inner cortex, where heat damage truly begins. Powered by patented resilicore™ heat-shielding technology, inspired by proteins in nature that can withstand extreme temperatures, HeatBounce penetrates deeper than ever before* to form a protective shield from within. Unlike conventional heat protectants that only coat the outer cuticle, this lightweight spray defends against heat up to 450°F (232°C) while softening, conditioning, and detangling even the most damaged hair. With 85% less breakage after blow drying*, it's a complete 2-in-1 solution that protects and conditions in a single step. Created for all hair types and textures, including extensions.
