Description
Full Size – 4oz
This leave-in conditioning heat protectant detangles, softens, and delivers deeper heat protection than ever before*—for 85% less breakage after blow drying⁷.
How to use
Apply throughout sectioned hair, brushing through to help with even distribution. Less is more. Start small and build as needed. Hair should feel soft and tangle-free, but not coated.
Use on towel-dried hair before blow drying and on dry hair before hot tools
More to know
resilicore™ heat-shielding technology is inspired by proteins in nature 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 hair’s inner cortex where heat damage can occur, forming a protective shield that fortifies from within.
Conditioning blend conditions, softens, and detangles even damaged hair
Created for all hair types + textures. Can be used on extensions.
Key benefits
Protects from heat up to 450°F
85% less breakage after blow drying⁷
Lightweight formula conditions, softens, and detangles even damaged hair

Is HeatBounce activated by heat?
No, HeatBounce does not need to be activated to protect from heat.
Do I have to wait to use heat after applying HeatBounce?
No, you can blow dry or use hot tools immediately after applying HeatBounce.
How is HeatBounce different from traditional heat protectants?
HeatBounce is powered by resilicore™ heat-shielding technology, an innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the outside cuticle layer of hair, 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.

What’s the difference between molecular repair hair oil and HeatBounce?
While the molecular repair hair oil and HeatBounce have heat protection benefits, HeatBounce defends against heat from the cuticle¹ to the cortex², going as deep as heat damage goes to help protect against color fade, dry feeling, dullness, and breakage. The oil delivers traditional heat protection on the outer layers of hair and clinically proven damage repair.

²Results observed as an increase in protein stability in scientific testing after application of HeatBounce on damp hair and exposure to 450℉ (232℃) flat iron on dry hair.
When do I use HeatBounce in my routine?
After shampooing, apply the K18 mask (wait 4 minutes) or DAMAGE SHIELD conditioner. Then, apply HeatBounce and AstroLift™ before blow drying or air drying. Use HeatBounce again before any hot tools. Finish with K18 oil and use AirWash™ to refresh hair between washes.
How often can I reapply HeatBounce?
Apply HeatBounce every time before you apply heat, including if you switch between blow drying to hot tools.
