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.

  • Conditioning blendconditions, softens, and detangles even damaged hair
  • Created for all hair types + textures
  • Can be used on extensions
  • Protects from heat up to 450°F
  • 85% less breakage after blow drying
  • Lightweight formula conditions, softens, and detangles even damaged hair

A little heavy for fine hair

This was a little heavy for my fine hair and didn’t do anything amazing for me. It smells nice, but I think there are better heat protectants on the market.

Sticky :(

I really wanted to like this product because I LOVE K18, but it’s extremely plastic-y and synthetic feeling, which makes it impossible to distribute evenly through hair. Maybe it just isn’t meant for me…
