Great way to keep your hair long and healthy. It really restores shine and makes it feel soft yet light. Not super heavy but very concentrated.

I’ve tried K18 products before & really like them. This leave-in conditioner did not disappoint. It makes my hair so soft and works well on extensions too. I like that it is also a heat protectant.

Works well, but it does have a particular scent and does make hair wet so is not great as a dry air protectant

How to
Apply to sectioned hair and brush through to ensure even distribution. Use on towel-dried hair before blow-drying, and on dry hair before using heat styling tools.
K18 HeatBounce Leave-In Conditioner and Heat Protectant is powered by advanced Resilicore heat-shielding technology to defend hair from the inside out. It protects against heat damage up to 450°F, while conditioning, detangling, and shielding hair from mechanical stress, UV exposure, and environmental factors that contribute to color fading, dryness, and breakage.Inspired by resilin—a natural protein known for its heat resistance—Resilicore is a cutting-edge innovation that goes beyond surface protection. Unlike traditional protectants that sit on the cuticle, Resilicore penetrates deep into the cortex, where heat damage begins, forming a powerful internal shield. Suitable for all hair types and textures, including extensions.
