Great heat protection
I have to say this is one of my new favorite heat protectants. I have thick very porous course hair and it usually takes a lot of heat protectant (Coates of it) to keep my hair smooth and not frizz. This doesn’t have me coating my hair so it’s worth every penny

Protection
This product has really helped protect my hair from the heat of the hair dryer which I use everyday. My hair came back after chemo very thin and dark so I have also been having it bleached and toned. The K18 products referred to me by my hairdresser have helped my hair from being damaged . This is one of the products I use.

Second Order
I have curly hair that I've bern growing out to gray for a year now. Heat Bounce has absolutely transformed my diffusing routine. My hair is softer, shinier, and the curl clumps are much smoother. I'm about to order it for the third time!
