K18 HeatBounce Conditioning Heat Protectant Spray 150ml

Protect your hair from heat damage while keeping it soft, smooth, and healthy looking with K18 HeatBounce Conditioning Heat Protectant Spray 150ml, an advanced leave in heat protectant designed to shield the hair fibre from high temperature styling while helping reduce breakage, frizz, dryness, and rough texture. Powered by K18’s patented Resilicore™ Heat Shielding Technology, this lightweight conditioning spray penetrates deeper into the hair fibre to help protect against heat damage from blow dryers, straighteners, curling irons, and hot tools up to 450°F / 232°C. 

Unlike traditional heat protectants that only coat the hair surface, HeatBounce is designed to penetrate into the inner cortex where heat damage actually occurs. Its conditioning cream to mist formula helps strengthen the hair from within while leaving strands softer, silkier, and easier to manage without sticky residue or greasy buildup.

Designed for all hair types and textures including damaged, colour treated, chemically processed, curly, fine, and extension hair, this salon quality heat protectant helps detangle and smooth while supporting healthier looking hair with continued use. Many users love how lightweight and non greasy the formula feels, while others praise its ability to leave hair softer and shinier after styling.

Infused with K18’s biotech inspired haircare innovation, HeatBounce helps deliver up to 85% less breakage after blow drying while protecting against daily styling stress and environmental damage.

Whether used before blow drying, straightening, curling, or everyday heat styling, K18 HeatBounce Conditioning Heat Protectant Spray delivers lightweight protection, smoother styling, and healthier looking hair without compromising softness or movement.
