I've had some highlights put into my mid brown hair but I really don't like them, probably because my hair is very short so they look really 'bitty'. If I used a brown dye over the top would it cover them or am I going to end up with green hair? There aren't loads (about 1/4 of my head) and they're not that light.
I know I should go back to the hairdresser but I don't want to complain as she only did what I asked for and I'm normally really happy with her.
