My hair is naturally dark blonde, I’ve been dying it for the past few years to a light blonde, I really want to go to an auburn colour beofre I go back to achool on thursday. I’ve bought a hair dye that says it will make my hair this colour- http://www1.cs.columbia.edu/CAVE/projects/separation/images/Hair_Auburn_Scene.jpg
The problem is that it says that it’s not suitable for already dyed hair. Is this just beacause the hair colour will come out a light ginger instead the of the darker colour or is it because the hair dye will be dangererous??? HELP
Dying my blonde hair auburn?(help I need to dye it tonight)?
