I'm a bit cross about this. I've always wanted one of these brushes and was bought one for Christmas. My daughter has thick wavy hair and has always struggled to find a brush that will not hurt when brushing. She got very excited about my brush, tried it and found it didn't hurt. So she used it daily and within a month I realised it had started clumping, dreadlock style, on the top surface of her hair.
I am still struggling to sort it out with comb and conditioner, a knot per night as it is so tangled. The hair is really damaged and looks like it has split along the shaft. I'm now going to have to give her quite a vigorous haircut (it's currently below her shoulder blades and the damage is at ear level).
Has anyone else experienced this? Should I contact them with photos?
