I honestly thought this was unnecessary at first like… “it’s just a comb.” But after using it while straightening my hair, I actually noticed my hair came out smoother and way less puffy. It’s heat-resistant and static-free, so it doesn’t get weird around hot tools and it helps smooth the hair while styling. Though, it is not something I need every single time, but whenever I use it, my hair definitely looks sleeker and more polished afterward.
