My heavily highlighted hair is starting to show the darker roots, about 2cm of growth there if I pull it flat. Though I'm dark blonde naturally the contrast is making my roots seem even darker.
Is there a box dye or something I could wash in to tone it all down? I'm wary of dabbling with root touch up as I've heard blonde is so hard to do. So thought maybe go darker instead?
Any good ideas, or shall I just wait it out?
