Unlike traditional heat protectants that sit on the surface, this haircare innovation reaches heat damage where it happens—the cortex—and offers protection up to 450°F and [reduces breakage by 85%](https://www.trendhunter.com/trends/true-professionals-grow-long) after blowdrying. Uniquely, HeatBounce has a high-performance [leave-in formula](https://www.trendhunter.com/trends/vegan-leavein-treatment) that goes from a lightweight cream to a fine mist that shields hair against not just heat but also mechanical damage and UV environmental damage, which can manifest as everything from faded color and dullness to dryness and breakage.
