Review (3/5): Brushes don't work for me but my brother likes them.
I cannot use the brush at all. I have very fine frizzy hair that is fairly thick with natural waviness. I cannot even run the brush through my hair without pulling so I gave the brush to my brother and he is satisfied. The brushes work for him. He has thinning grey hair and the brushes are perfect for his needs.
My hair texture is unique so I don't anticipate other people having my problem.
