Why you need it

K18 HeatBounce Conditioning Heat Protectant isn’t your average heat spray, it’s a breakthrough in damage prevention. Using Resilicore™ heat-shielding technology, inspired by proteins found in nature that can endure extreme heat, the K18 HeatBounce goes deeper than traditional heat protectants. Instead of sitting on the surface, K18 penetrates the inner cortex where heat damage starts, building a protective shield from within. Hair feels softer, smoother, and more manageable while staying strong against the daily stress of styling. Whether you’re blow drying, curling, or straightening, you’ll get conditioned, detangled hair with 85% less breakage and lasting protection. Plus, the K18 heat protectant is lightweight enough for every hair type and even safe for extensions.
