I have dark brown almost black hair naturally. I boxed dyed it red for a couple years but of course it never got as bright as i want it. I feel like it just made my hair darker but with a red tint in the sun . If i want to dye it brighter burgundy/ cherry at home using a developer and better hair dye do i need to use a color remover first? Last time i boxed dyed was over a year ago
