HeatBounce Conditioning Heat Protectant
A conditioning heat protectant formula powered by resilicore™ heat shielding technology to help prevent heat damage up to 450°F from the inside out, condition and detangle hair, and defend against heat, mechanical, and UV environmental damage that can cause color fade, dryness, dullness, and breakage.
This leave-in conditioning heat protectant detangles, softens, and delivers deeper heat protection than ever before*—for 85% less breakage after blow drying.
resilicore™ heat-shielding technology is a breakthrough innovation inspired by resilin—a natural protein that can withstand extreme temperatures.
Unlike traditional heat protectants that only coat the cuticle, the size + molecular makeup of resilicore™ allows it to penetrate deeper than ever before*, into the cortex where heat damage can occur, forming a protective shield that fortifies from within.

- Can be used on extensions
- Protects from heat up to 450°F

Sticky and smells bad w heat
Wish I’d waited for the mini to come out to try this, but I got a full size because I was so excited to “upgrade” to K18. I hate it. It tangles my hair. It smells bad when heated, which is the point of a heat protectant.
