I have just used this brush

and it worked an absolute treat on my long curly hair which can get very knotted. It really was like magic. However quite a bit of hair came with it - it was not pulled out roughly though. Does anyone know if these are supposed to be good/bad for hair (e.g. does it cause split ends?) as it certainly does the job excellently. Thanks
