K18 Biomimetic Hairscience HeatBounce Mask + Oil 3-Piece Travel Kit

A compact K18 routine for hair that needs repair, heat protection, and smoother-looking finish after color, lightening, chemical services, or regular heat styling.

What it does

• Repairs visible damage: K18PEPTIDE™ helps address damage associated with lightener, color, chemical services, and heat.
• Protects against heat: HeatBounce conditioning heat protectant helps protect hair up to 450°F / 232°C while conditioning and smoothing.
• Finishes with lightweight shine: Molecular Repair Hair Oil helps reduce the look of frizz, smooth the ends, and add shine without replacing the repair mask or heat protectant.

Kit includes

• Leave-In Molecular Repair Hair Mask — 0.5 fl oz
• HeatBounce Conditioning Heat Protectant — 1.6 fl oz
• Molecular Repair Hair Oil — 0.34 fl oz

How to use

After shampooing, apply the K18 mask to towel-dried hair before conditioner, wait the full 4 minutes, then apply additional styling products if needed. On heat-styling days, apply HeatBounce to towel-dried hair before blow-drying and follow the product directions before additional hot-tool use. Use a small amount of the oil on dry mid-lengths and ends for finishing. Do not layer the mask with another intensive repair mask in the same wash.

For chemically treated or lightened hair, this kit supports the home-care phase between professional assessments. It does not replace an in-salon repair service or a professional colorist’s decision about additional lightening.
