Was very skeptical that itd actually work but it really does. I've always had the type of hair that the more you comb it the more it tangles! Lol. I've died it for years now and once I recently decided to perm it, it was damaged even more and was impossible to comb wet no matter how much conditioner I used. This comb makes it so much easier. It may take just a tad longer, but atleast I'm not pulling out globs of tangled hair anymore. It holds a charge good too. Had it atleast a month and have only charged twice.
