My hair is bleached with highlights. The colour is going a bit dull and brassy and I've a few things coming up so I'd like to look my best. Can't get an appointment for highlights that works for me for another 3 weeks. In the meantime I'm wondering if it would help to use a "purple" shampoo, Color Wow dream filter or L'Oreal Metal Detox or a mix of things? I don't have a platinum or ash look to my hair it's more a light golden blonde.
If anyone knows about this sort of thing, what would you recommend?!
