more to know

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.

got questions?

is heatbounce activated by heat?

No, HeatBounce does not need to be activated to protect from heat.

Do I have to wait to use heat after applying HeatBounce?

No, you can blow dry or use hot tools immediately after applying HeatBounce.

How is HeatBounce different from traditional heat protectants?

HeatBounce is powered by resilicore™ heat-shielding technology, an innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the outside cuticle layer of hair, 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.

What’s the difference between molecular repair hair oil and HeatBounce?

While the molecular repair hair oil and HeatBounce have heat protection benefits, HeatBounce defends against heat from the cuticle¹ to the cortex², going as deep as heat damage goes to help protect against color fade, dry feeling, dullness, and breakage. The oil delivers traditional heat protection on the outer layers of hair and clinically proven damage repair.

²Results observed as an increase in protein stability in scientific testing after application of HeatBounce on damp hair and exposure to 450℉ (232℃) flat iron on dry hair.

When do I use HeatBounce in my routine?

After shampooing, apply the K18 mask (wait 4 minutes) or DAMAGE SHIELD conditioner. Then, apply HeatBounce and AstroLift™ before blow drying or air drying. Use HeatBounce again before any hot tools. Finish with K18 oil and use AirWash™ to refresh hair between washes.

How often can I reapply HeatBounce?

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

      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! ❤️

      This new, more renovated product works super well with my hair. It softens my hair and at the same time protects it from heat and provides easy detangling and moisturizes because my hair is left with such a beautiful shine and protection, ready to dry with my hot hair tools.

      I’ve never before used a K18 Biomimetic Hairscience product and now I see why it’s been talked about so much recently. This brand truly uses better ingredients to help protect your hair from damage. I don’t tend to straighten my hair very often. I have damaged and thinning hair.

      Complimentary from K18 Biomimetic Science. Love using this as a leave in conditioner even without using heat tools. I feel like it helps protect my hair from the summer heat. Controls frizz and smells good!

      Gifted by K18 Biomimetic Hairscience. This leave-in conditioner is amazing! It makes my hair feel soft, smooth, and tangle-free while protecting it from heat up to 450°F. The lightweight formula doesn’t weigh my hair down, and I’ve noticed way less breakage after blow-drying.

      I love K18 hair products so much because they WORK. I was really excited to try this HeatBounce Conditioning Heat Protectant and I noticed a difference in my finished hair from the first time using it. I’ve applied it to my hair wet and dry (depending on how I style it) and love the results both ways. Gifted by k18biomimetichairscience
