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 2-3 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.
