HeatBounce - Heat protection from the inside out.

A breakthrough heat protectant powered by the patented resilicore™ technology — inspired by proteins found in nature that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the cuticle surface, resilicore™ is small enough to penetrate the hair's inner cortex, forming a protective shield from within, where heat damage actually occurs. Results you can expect: True heat protection from the inner cortex outward — not just a surface coating Patented resilicore™ biotechnology inspired by heat-resistant proteins in nature Conditioning blend softens, detangles, and smooths even damaged hair Works on all hair types and textures Safe for use on extensions and weaves Lightweight formula that protects without weighing hair down Apply to damp, towel-dried hair before blow-drying, flat-ironing, or any heat styling. Distribute evenly from mid-lengths to ends — add more for thicker, coarser, or more damaged hair. Comb through to coat every strand, then style as usual. Use it every time you apply heat. Pair with the K18 Leave-In Molecular Repair Hair Mask for compounded protection and repair, or layer with the K18 Molecular Repair Hair Oil for added shine and frizz control during styling.
