Read on to find out when, how, and where to use HeatBounce conditioning heat protectant in the salon.
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.
Clients going heat-free but still want leave-in conditioning and detangling benefits? Apply HeatBounce on towel-dried hair before air drying, Young recommends for her wash-and-go clients. “The lightweight conditioning blend makes their hair more pliable and defined without weighing it down. It’s the perfect foundation for easier styling.”

You’ve got heat protection covered in the salon, but clients often use heat to touch up their styles. Now you can recommend HeatBounce, so they can look + feel their best without compromising hair health.
Alifia tells her clients to shield from damage before any styling touch-ups, even if there’s no heat involved. “The cream-to-mist formula won’t revert their style, and their hair will get stronger over time*. It’s a win-win!”
Now you’re primed to blow dry, straighten + curl every client—sans breakage, buildup + heat damage. HeatBounce has all hair types protected: no scorched strands in sight.
So go ahead, turn on the heat.
