My hairdresser always recommends this line. Also a neighbour of mine is a hairdresser and she says that it's the best hair care line available on the market. I have tried a couple of products and I'm not sure if they are any better than some of the other lines I've tried. Actually I think the volumizing shampoo I tried made my hair really dry. I also used the leave-in conditioner and it didn't really condition my hair. Any opinions about this line? Good or bad?
