Step 1
Bleach the hair. It removes the black dye but comes with consequences. Visit a salon and have it professionally done. Bleaching causes stress to your hair and often leads to thinning and breaking. Salons have products available to counteract some of these negative effects. Talk with your stylist about assessing the needs of over-dyed hair.

Step 2
Use an at-home dye removal product. There are two that are widely available. Try Color Fix by Jheri Redding or L'Oreal Color Zap. Both remove black hair dye, but they leave your hair in a state that needs to be re-dyed. Deep condition your hair the day after you use these products to let it rest. Re-dye it only after using a deep conditioner.

Step 3
Try scrubbing out the black hair dye. If you have just dyed your hair, you have a much greater chance at success. Apply a strong dandruff shampoo to get the black dye out. Scrub your hair vigorously and repeat the process several times. Apply the strongest conditioner you can find. Make sure that it is not color safe to help remove the color.

Step 4
Perform a hot-oil treatment on your hair. Hot oil treatments have been known to lift dyes out of hair. Better results are reported with brown and red dyes, but it is certainly worth a try. Follow the package instructions for correct application techniques.
