I've heard from people that they are bad for your hair, but I'm not sure why. I have one that is a combination boar bristle and knobby plastic tipped brush. I don't think it catches in my hair.. In the past I've bought cheap 100% boar bristle brushes and I found that not only do they not go through my hair, but they leave it looking flat and stuck to my head. The combo brush has been the only brush I've tried and liked so far.
