Ok. I know what you’re thinking. I thought the same thing when my hubs came home with 3 of these. “How is that going to work?!🙄”. But I said I’d try it and it’s now my go to every morning with my 6 year old. It works kind of like your fingers do except hair slides off it. Bcz it’s minimal teeth that are very long it gets in there and then slides out taking a tangle or two out each brush thru. The flexibility means it never gets stock or pulls. These retail $25 in stores (smh 😲).
