well if your hair is a light color like blonde if you want to go back to your natural color which is a brown you have to fill it in with like a red and then go and deposit the color that you want it to be because thats the color your missing in your hair. if you want it lighter then try washing your hair with dawn dish soap because it strips the hair of the color. or else you can try a malibu treatment that strips the color out as well if you have colored your hair within a few days. or else you can bleach it but it will be hard on your hair to get the color out.

hope i could help
