don t see a difference [SEP] i will preface this with the fact that i previously had a heated ionic hairbrush and it was amazing but broke after years of minimal use i don t feel like this brush is doing anything for my hair and maybe my hair is too thick but i can t even feel the massage function my daughters hair is crazy and curly and when i brush it through her hair is tamed for a minute but then just right back to craziness so i don t know if it s really working
