Blow dry, curl + straighten without the damage.
The truth is, we should all be using a heat protectant every time a hot tool comes near our hair. Blow dryers, flat irons, curling wands, diffusers–you name it—every single one of them can and will damage hair regardless of type, density, or texture.
And here’s the kicker: not all damage is immediately visible. It can build cumulatively over time. So what started as a little extra frizz and a few split ends can eventually turn into something far more serious—dull, dry, brittle hair that’s structurally compromised and far from its healthiest state.
That’s why we created HeatBounce conditioning heat protectant—a first-of-its-kind heat protectant designed to safeguard all hair types from heat up to 450°F (for context, that’s pretty much the max temperature most at-home ovens can safely go) deeper than ever before*.
the HeatBounce difference
Inspired by resilient proteins found in nature, which are known for their ability to endure extreme stress and temperature, HeatBounce is powered by patented resilicore™ heat-shielding technology to protect hair from cuticle to cortex*. Unlike traditional heat protectants that only coat the surface, the size and molecular makeup of resilicore™ allows it to penetrate as deep as heat damage goes, forming a flexible protective shield that fortifies hair from within and literally bounces damage away.

Lightweight and buildable, HeatBounce is highly versatile and performs on wet or dry hair (including human hair extensions) in every heat-styling scenario. It’s designed to be used multiple times in one session without adding extra weight or leaving behind residue.
Plus, thanks to a nourishing conditioning blend, it also functions as a leave-in conditioner–softening and detangling for smooth, shiny, bouncy hair and consistent salon-level results. Plus, the longer you use it, the healthier and stronger your hair gets*.

Adhering to the same less-is-more approach as all the rest of your K18 routine, getting the best results from HeatBounce follows the same easy-to-remember steps:
Apply a small amount to towel-dried, sectioned hair before blow drying to reduce breakage by up to 85%*.
Reapply on dry hair before flat ironing, diffusing, curling, or silk pressing for additional protection.
Finish with K18 molecular repair hair oil for 24-hour frizz control and extra shine–and voilà!
Heat protect, condition + detangle in 1 step = your key to damage-free heat styles, every time.
