The Future of Heat Protection

Professional Only

Log In / REGISTER

Description

The future of heat protection. This leave-in conditioning heat protectant detangles, softens, and delivers deeper heat protection than ever before*—for 85% less breakage after blow drying*.

*k18hairpro.com/disclaimers

Apply throughout sectioned hair, brushing through to help with even distribution. Less is more. Start small and build as needed. Hair should feel soft and tangle-free, but not coated. Use on towel-dried hair before blow drying and on dry hair before hot tools.

Resilicore™ heat-shielding technology is inspired by proteins in nature that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the cuticle, the size + molecular makeup of resilicore™ allows it to penetrate deeper than ever before*, into hair's inner cortex where heat damage can occur, forming a protective shield that fortifies from within.

Conditioning blend conditions, softens, and detangles even damaged hair.

Created for all hair types + textures. Can be used on extensions.

HeatBounce is powered by resilicore™ heat-shielding technology is a breakthrough innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the cuticle, the size + molecular makeup of resilicore™ allows it to penetrate deeper than ever before*, into the cortex where heat damage can occur, forming a protective shield that fortifies from within.
Apply HeatBounce every time you apply heat, including if you switch between blow drying to hot tools.
First apply the PRO mist, wait 4 minutes, then shampoo and skip conditioner. Apply the PRO mask, and wait 4 minutes. This is when you apply HeatBounce and AstroLift™ before blowdrying or airdrying. If using hot tools, apply HeatBounce again. Finish with K18 oil and use AirWash™ to extend the look out of the salon, and recommend clients to use it between washes.
No. HeatBounce features a new K18 innovation—resilicore™ heat-shielding technology. This innovation is inspired by resilin—a natural protein known for its ability to withstand extreme temperatures and store energy. resilicore™ penetrates deep into hair’s cortex, forming a protective shield that fortifies the hair from within.

    Awesome protectant!

    I’ve tried a fair share of different heat protectants. This one takes the cake! No overwhelming smell, doesn’t weigh down my fine hair, and protects against all of my heat tools. Love it!!! I’ll be recommending this to everyone! ❤️

    Awesome!

    *I was gifted this product from K18 to review. My opinions are my own*

    My thick curly hair can sometimes be an issue for me personally to manage daily. So, I prefer to straighten my hair to better maintain it. Products I've used in the past never gave me the results I was hoping to achieve. It was always disappointing for me. This heat protectant spray from K18 has been amazing for my hair so far. My hair feels soft and it has a nice, lightweight bounce to it. It gives my hair moisture and it's easy to run my fingers through. The great protection I get from this, when using my flat iron, is something that I haven't experienced from previous products. The product also smells great and the texture makes it very easy to apply to my hair each time. I definitely recommend
