I really like using this brush on my extensions but it’s not great at getting knots out. Also when I brush my U-Clip with it the bristles keep getting caught in the clips and have ripped a lot of the ends of the bristles off which was really irritating. After I get the knots out with a separate brush, this brush is great to freshen and fluff the hair. My daughter loves it on her natural hair because it doesn’t hurt her (she has waist length wavy thick hair) but I always have to go back over her hair with a different brush if there are knots in it. It’s really more of a finishing brush and I’m glad I bought it but disappointed that so many bristle tops ripped off so easily. And $25 is a lot for a brush that doesn’t get knots out and even does a poor job of getting minor ones out. I think they should mix in some harder bristles in there for knots. But it does a great job of making the hair look pretty, soft and fluffy for wear.
