Can anyone recommend good shampoo for DD (13), with long, fine hair? It's always been really silky but has in the last month or two become very dry and frizzy - should she start using conditioner now? (I can't remember when I started using it myself.) She doesn't blow-dry, or use anything else after washing it.
She's also v eco-conscious, so anything that way inclined would be good, too.
TIA x
