how to use HeatBounce conditioning heat protectant

by CHAD STEVEN GILMORE on Oct 27, 2025
how to use HeatBounce conditioning heat protectant

Blow dry, curl + straighten your hair—without damage. 

So you’re ready to heat protect deeper than ever before, but don’t know where to start? Here’s everything you need to know—straight from Alifia Young, K18 Sr. Manager, Education + Training. 

how to use HeatBounce conditioning heat protectant

Read on to find out when, how, and where to use HeatBounce conditioning heat protectant in your routine. 


When to use HeatBounce

Anytime you’re using heat, apply HeatBounce first. Even lower levels of heat cause deep damage that can lead to dullness, dryness, color fade, and frizz, but fret not—HeatBounce has you covered. Powered by resilicore™ heat-shielding technology, HeatBounce protects hair from cuticle to cortex* up to 450°F. Apply before blow drying on towel-dried hair, and before curling or straightening dry hair. 


Going heat-free but still want leave-in conditioning and detangling benefits? Young recommends applying HeatBounce on towel-dried hair before air drying for her wash-and-go clients. 


“The lightweight conditioning blend makes their hair more pliable and defined without weighing it down,” she says. “It’s the perfect foundation for easier styling.”


how to use HeatBounce

Like all of K18’s highly concentrated formulas, HeatBounce was designed to do more for hair with less. Use it like this:


Apply HeatBounce throughout hair, start with 3 sprays total and add more as needed, then brush through to help with even distribution. No need to wait for anything to activate, you can style immediately.

where does HeatBounce go in my K18 routine?

Start by shampooing your hair, and follow with the K18 leave-in molecular repair mask or DAMAGE SHIELD conditioner (depending on your routine that day). 


Alifia recommends using the mask for a strong base and resilient hair that can take on any heat style. After the 4-minute mask wait time, apply HeatBounce. 

Next, go in with AstroLift™ reparative volume spray for a lifted look, and begin blow drying, diffusing, or wait for hair to air dry. Use HeatBounce again before any hot tools, and finish with the molecular repair hair oil for added shine. 


Between washes, you can use AirWash™ dry shampoo to refresh hair, and HeatBounce to protect and condition before your styling touch-ups. 


Now you’re ready to blow dry, straighten + curl—sans breakage, buildup + heat damage. HeatBounce has you protected: no scorched strands in sight. 


So go ahead, turn on the heat.
