My hair is naturally quite a dark brown, but I was dying my hair a very bright red colour for about two years, and eventually stripped it at home myself about two months ago. It's now an auburn colour. I stripped it as I want to go a dark blonde, caramel colour but don't know if I should go for a block colour, or have highlights and build up the colour, or even if I should maybe start with dip dye and work my way up! any suggestions?!?!?
