Review (4/5): Not magical, but definitely helpful!
I bought this brush for my toddler. She has very fine hair and it's always getting tangled, but she is pretty intolerant of my detangling attempts. Although this brush can't make every knot painless, it is very helpful! The material and shape of the brush prevents snags and the give in the bristles allows me to work through those knots without accidentally ripping her hair or hurting her. I plan on buying a second!
