I buy something from Amazon everyday and I have never written a review until today. This is an amazing brush. My daughters hair always gets knotted, I mean crazy knots looks like a birds nest. I used this brush as soon as I got it and it detangled my daughter’s hair in less than 5 min. She didn’t cry or anything. I took some pics a before and after but I took it after it detangled more than 50 percent of her hair.
