I was growing out highlights that were too ashy. As my roots became obvious I started using nice n'easy 8 wash (colour you don't have to mix up).
Now I'm thinking I would like to tint my hair a light brown (natural colour is mid brown) to colour the grey - I'm 15% according to one hairdresser.
My question is - does a wash put dye ever really wash out i.e will a permanent dye not work? Thank for advice in advance..
