What is the best way to lighten hair after putting in hair too dark a colour?
I would really do it professionally! You have no idea how your hair may turn out if you do it yourself. Also, hair always lightens after a few washes when you dye it too dark. You can always buy a clarifying shampoo, which will help get the color out faster. Another thing you can do, but which is also very damaging to your hair, is to mix a bottle half with shampoo and half with dish soap and wash your hair with it. You would have to use LOTS of deep conditioner afterward, though– dish soap is not good for your hair at all. One way to VERY GRADUALLY lighten hair is to get a spray bottle, and mix half hydrogen peroxide and half water in it. When you get out of the shower, spray it all over your hair and comb it through. This will lighten it about half a shade every time you do it.
