The hair dye colour that is promised on the box may not always be what ends up on your hair. Maybe you’re hair came out too light or too dark, or you simply do not like the colour. Whatever the reason, there are a few ways that you can get the majority of hair dye out of your hair.
Re-wash your hair. It is hard to get all of the hair dye out of your hair to begin with, so rewashing can help rid the hair of excess dye. Use plenty of shampoo and lather well. Be sure to always condition your hair after each washing, to avoid excess drying.
Try using dish soap as a shampoo. It sounds silly, but it is an old homemade trick that actually helps get rid of hair dye. The harsh ingredients of the soap will help strip your hair of the colour, while cleaning your hair. Again, use plenty of conditioner afterwards.
Try a peroxide cap. This method can really get the colour to come out of your hair. Buy 30-volume peroxide from any beauty shop near you. Mix it, per part, into you’re usual shampoo, and shampoo your hair with it. Leave it in for 5 to 10 minutes, and rinse. Again, repeat as necessary, always conditioning well afterwards.
Visit your local hairdresser, if all else fails. They can help you get rid of the hair dye by stripping your hair of the colour. Try to do so within a week of colouring your hair, so that they have the best chance of getting all the colour out.
Always use plenty of conditioner.
Consult a hairdresser if you have excess drying or similar damage to your hair.
