Why Is My Hair Green After Dying It Brown?
If your hair has turned green after dying it brown, it is likely due to the previous color of your hair and the products used during the coloring process. This green tint can be caused by the combination of brown hair dye and the remaining tones of red or copper from a previous color. Additionally, if the hair dye used had a blue or green undertone, it could react with the remaining tones in your hair, resulting in a green hue. A professional colorist can help correct the color and give you the desired shade of brown.
