K18 HeatBounce™ Conditioning Heat Protectant

What It Does

K18 HeatBounce is the first conditioning heat protectant to defend hair from the cuticle to the cortex — going as deep as heat damage actually occurs. Powered by resilicore™ heat-shielding technology, a breakthrough innovation inspired by resilin (a natural protein that withstands extreme temperatures), HeatBounce forms a protective shield inside the hair, not just on the surface. The result: 85% less breakage after blow-drying, softer hair, and superior protection against colour fade, dullness, and dryness from heat.

Key Benefits

•       Inside-out heat protection up to 450°F / 232°C

•       85% less breakage after blow-drying

•       Defends against heat damage from the cuticle through to the cortex

•       Protects against colour fade, dullness, dry feeling, and breakage from heat

•       Lightweight leave-in conditioner that detangles and softens

•       No need to wait — apply and blow-dry or use hot tools immediately

•       Safe for all hair types

Who It's For

Anyone who blow-dries or uses hot tools regularly. Ideal for colour-treated or bleached hair that's more vulnerable to heat damage, and for anyone seeking both conditioning and deep heat protection in one step.

How To Use

After shampooing, apply the K18 mask (wait 4 minutes) or DAMAGE SHIELD conditioner. Then apply HeatBounce throughout sectioned hair, brushing through to help with even distribution. Use on towel-dried hair before blow-drying and on dry hair before hot tools.
