Does dish liquid help lighten permanent hair dye?
i used revlon hair dye and it was supposed to be dark brown but it turned out jet black instead. i do not like ti at all and i heard that using dawn dish liquid will lighten hair. does it work on permanent dye?
It can sometimes help to fade the color, but it won’t remove the color all together.
I think baking soda mixed in your shampoo works better to fade color though.
