I’ve never dyed my hair by myself before, but I couldn’t get to a hairdressers to have my roots done so I thought I’d try at home. I’ve ended up with this. It’s not terrible and I haven’t put a colour on it yet but I don’t know if I need to do the bleach again to cover the areas of auburn that are still showing mixed into the blonde. What do I need to do? Will the box dye cover it??
