Brush through sectioned hair for even coverage. Start light — you can always add more. Hair should feel soft, smooth, and tangle-free, without any heavy coating.

Use on towel-dried hair before blow-drying, or on dry hair before heat styling.

Protects hair from heat (up to 232°C)
85% less breakage after blow-drying*
Lightweight conditioning for softer, smoother, tangle-free hair

Powered by resilicore™ heat-shielding technology —modelled after proteins that thrive under extreme heat — this formula goes deeper than traditional protectants. Instead of coating the surface, resilicore™ penetrates the inner cortex to form a shield that defends against damage and strengthens from within.

A lightweight conditioning blend smooths, softens, and detangles — even distressed strands.

Suitable for every hair type, texture, and extensions.

how to use HeatBounce conditioning heat protectant

1. Apply throughout sectioned hair, brushing through to help with even distribution.

2. Less is more. Start small and build as needed. Hair should feel soft and tangle-free, but not coated.

3. Use on towel-dried hair before blow drying and on dry hair before hot tools.

got a question?

No, HeatBounce does not need to be activated to protect from heat.

No, you can blow dry or use hot tools immediately after applying HeatBounce.

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.

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 colour fade, dry feeling, dullness, and breakage. The oil delivers traditional heat protection on the outer layers of hair and clinically proven damage repair.

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.
