Removing Black Hair Dye From Hair - Tips From Site Visitors
Suave's Clarifying Shampoo or Clairol's Herbal Essences Clarifying/Residue Removal Shampoo. Both are good for taking out hair dye better that most shampoos.
Visit a hairdresser and try to get it lightened.
Visit a hair supply store and buy some powder bleach or get a streaking kit with powder bleach from the drugstore. Add equal parts water and a shampoo/conditioner blend. Mix thoroughly until it has a creamy consistency. Apply evenly and quickly. Emulsify like you are applying shampoo and keep an eye on it with a mirror and when you see it lighten a bit, remove. Repeat as neccesary, usually once or twice should do the trick. By swapping the water/shampoo/conditioner mix for the peroxide, it slows down and weakens the overall bleaching process and gives you more room for error.
