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.

Apply HeatBounce every time you apply heat, including if you switch between blow drying to hot tools.
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.

    Heat Bounce conditioning heat protectant

    This stuff is the best heat protector I have ever used. It smalls heavenly like all of their products. This is a weightless formula it leaves your hair feeling so soft and moisturized. My hair literally feels so voluminous and incredible. I have a lot of hair but it’s very fine. This doesn’t weigh it down at all. K18 has saved my hair!!

    Amazing find! Even better with the hair mask!

    Amazing! Love the heat protectant and the hair mask! It’s been transformative for my frizz prone hair (in the south too). I have a TON of hair products and these two are quickly becoming my favorites and will probably replace all others

    I love this stuff!

    This stuff is amazing! My hair looks and feels so good after using it. Knowing that I’m protecting it from heat damage while also rocking fabulous hair is worth it for me. I felt a bit disappointed with the size of the bottle but you don’t really want to use a lot, start small and build up. Cropped pic for privacy but look how amazing my end look using it.
