The K18 HeatBounce™ Conditioning Heat Protectant is a next-generation thermal shield that protects hair from heat damage up to 450°F/230°C while smoothing, conditioning, and strengthening every strand.

Powered by K18’s biomimetic peptide technology and Heat-Activated Molecular Repair, it helps restore resilience, reduce breakage, and lock in softness and shine. The lightweight formula delivers long-lasting frizz control and leaves hair smooth, bouncy, and protected after every styling session.

Who's it for?

All hair types, especially damaged, dry, or colour-treated hair frequently exposed to heat styling.

Apply 2–6 sprays evenly to damp hair before blow-drying or heat styling. Comb through to distribute evenly, then style as usual. Use before all heat tools for maximum protection and smooth results.

As self-described hair care ‘liberators’, K18’s ethos is all about supplying you with the tools you need to express your identity, try new trends and have fun with your mane — without sacrificing the softness, strength and vitality of your hair.

By understanding the biology of your hair the K18 team has been able to get to the (*ahem*) root of the problem of hair damage, and — crucially — discover one hero bioactive peptide that will return strands back to their most healthy state.

Enter: the K18Peptide, a patented molecule that travels to the polypeptide chains (that’s the very innermost layer of your hair) where it repairs broken bonds and restores hair’s strength and elasticity. This is where biotech meets hair care!
