K18 HeatBounce Heat Protectant

Heat Protection That Also Repairs While It Shields

K18 HeatBounce is not a standard heat protectant. In addition to shielding hair from heat damage up to 450 degrees Fahrenheit, it contains K18PEPTIDE, which continues repairing broken bonds in the hair while you style. Most heat protectants just prevent damage. This one does that and actively repairs existing damage at the same time. If you use heat styling regularly on hair that is already compromised, this is the product to use every time.

Best For

• Color-treated, bleached, or chemically processed hair that is regularly heat styled
• Anyone using flat irons, curling irons, or blow dryers regularly
• Hair that is both damaged and heat-styled often
• Anyone in a K18 repair routine who styles with heat

What It Helps With

K18 HeatBounce protects against heat damage up to 450 degrees while the K18PEPTIDE in the formula works on broken keratin bonds in the hair shaft. Every time you apply heat, you normally risk adding more damage. With K18 HeatBounce, you are actively repairing between styling strokes. The product also adds a conditioning benefit that leaves hair feeling soft and manageable after heat styling rather than dry and brittle.

Why Clients Love It

Clients who know they should use heat protectant but have never found one that makes a visible difference in their hair texture love K18 HeatBounce. It is the first heat protectant many clients have used that seems to actually improve their hair over time rather than just prevent it from getting worse. For anyone who blow dries or flat irons regularly on already-damaged hair, this product works genuinely harder than anything else in this category.

How to Use

Apply to damp or dry hair before heat styling. Spray evenly through mid-lengths and ends and comb through for even distribution. Style with heat as usual. Use every time you apply heat tools.

Pro Tip From Our Stylists

Apply to damp hair before blow drying and then again before using a flat iron or curling iron on dry hair for double protection. The K18 peptide is heat-activated, so more heat exposure after application gives it more opportunity to work.
