K18 Heatbounce Heat Protectant up to 230°C

K18 Heatbounce is a leave-in thermal protector that defends hair from heat up to 230°C, reducing breakage by 85% during blow-drying. Formulated for damaged, fine, or treated hair that needs protection during heat styling.

What is K18 Heatbounce

It is a leave-in heat protection treatment based on biomimetic technology. The lightweight formula creates a protective barrier that withstands high temperatures from flat irons, curling irons, and hairdryers. It contains conditioning agents that detangle and soften the hair fiber without weighing it down.

Who It's For

Ideal for those who regularly use thermal tools and want to prevent heat damage. Particularly effective on damaged, fragile, fine, or chemically treated hair. Suitable for those looking for a product that simultaneously protects and conditions without leaving residue.

Technology and Ingredients

K18's biomimetic technology replicates the natural keratin structure to integrate perfectly with the hair fiber. Conditioning agents form a protective film that evenly distributes heat and prevents dehydration. The formula is free of heavy silicones that can build up over time.

Apply to damp, towel-dried hair, distributing evenly from roots to ends. Comb through to ensure complete coverage. Proceed with blow-drying or styling with a flat iron/curling iron. Do not rinse. Can be used daily before any heat treatment.
