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.

I love it
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. It has a rich aroma that I love and beautiful packaging that truly meets all my expectations.

A staple hair product
I really love this new K18 spray. The mist is so fine but so effective in spraying a wide section of hair. I love how easy it was to spray and although it is a deep conditioner product too it is not heavy but leaves your hair feeling super smooth and silky and nice! I absolutely love how this is also a heat protectant. Trust me go with this one, a little spray goes a long way and I think it’s worth it! It also has a really nice fragrance

Dull hair to an wake and volumizing feeling.
I was gifted this product through Gloss Angeles Confidential and WOW HeatBounce by K18 is officially my hair’s new ride-or-die! 🙌 I’ve been blow-drying and flat-ironing more than usual (hello content creation and mom life), and this gem actually made my hair feel healthier after styling. It gives that soft, bouncy finish without the greasy buildup or weight. My ends don’t feel crispy, my shine is back, and the protection up to 450°F is no joke. Bonus? It smells luxe. Like salon day at home. If you love your hair but also love your hot tools, this is your secret weapon!

Game changer for blow drying 🔥
K18’s HeatBounce is the heat protectant I didn’t know I needed. It made my hair feel soft, strong, and super manageable - even after blow drying then braving the extreme heat and humidity in the southeast U.S. I love that it def mangles and protects up to 450°F without weighing my hair down. I didn’t need to curl or straighten after blow drying because my hair was already quite smooth. Plus, it actually conditions while it protects! Total win for anyone who styles often and wants healthier hair with less breakage.💁♀️👏🏻
