I'm after some recommendations for shampoo/conditioner/other stuff such as leave in serums for my youngest DD (aged 12). Her hair is naturally blonde and wavy, but it is incredibly dry and frizzy to the point of being almost unmanageable! She is starting to say that she hates her hair, and is feeling self conscious about it at school. We've tried quite a few different things, from supermarket brands, SLS free, diffent sorts of serums, hair masks, and leave in products...but nothing seems to make it less frizzy. At the moment she is using a Tigi shampoo/conditioner for dry/damaged hair which leaves my hair smooth and shiny, but it doesn't help hers at all!
Any recommendations of what to use/how to beat the frizz would be most gratefully received!
