K18 HeatBounce Conditioning Heat Protectant Spray — 1.6 fl oz Lightweight Leave-In, 450°F Heat Protection

This compact 1.6 fl oz conditioning spray from K18 is designed for everyday styling: a fast-absorbing, non-greasy mist that conditions cuticle-to-cortex, helps smooth and detangle, and shields hair from high-heat tools. Formulated to layer under styling products, it works on all hair types and textures without weighing hair down or leaving residue.

How does HeatBounce protect hair from hot tools?

HeatBounce creates an invisible, lightweight barrier that helps guard internal and external hair structure during heat styling. It’s formulated to withstand temperatures up to 450°F (232°C), so it’s suitable for high-temperature styling tools while still remaining light and workable.

• Provides inside-out protection from cuticle to cortex
• Heat resistance up to 450°F (232°C)
• Fine mist for even, full-length coverage

Will this leave my hair feeling heavy or sticky?

No — HeatBounce is a lightweight leave-in conditioning spray that absorbs quickly and keeps hair soft without buildup. It’s formulated to smooth and detangle while preserving natural movement, so styling remains flexible and touchable.

• Fast-absorbing, non-greasy texture
• Conditions without weighing hair down
• Compatible with layered styling products

How should I use HeatBounce for best results?

Spray evenly through damp or dry hair before using heat tools or styling. Focus on mid-lengths to ends to tame tangles and add protection, then proceed to blow-dry, flat iron, or curling iron as usual. A little goes a long way, so start with a light mist and add more if needed.

• Shake and hold 6–8 inches from hair for even application
• Use on damp hair to aid detangling and blow-drying
• Reapply lightly on dry hair before high-heat styling

What improvements can I expect after regular use?

With consistent use as part of your styling routine, HeatBounce helps reduce blow-dry breakage and leaves hair feeling smoother and easier to comb. It supports healthier-looking strands by minimizing stress during heat styling without altering your finished look.

• Reduced breakage after blow-drying when used as directed*
• Softer, smoother texture and improved manageability
• Detangles hair for faster styling sessions

Who is this for: K18 HeatBounce Conditioning Heat Protectant Spray suits anyone who uses heat tools and wants light, effective protection—ideal for fine, medium, or thick hair and for color-treated or natural textures. It’s a practical pick for daily stylers, professionals needing a travel-sized protective mist, and anyone seeking easier detangling and softer results without heavy silicones or residue.
