Depending on your original hair colour, certain hair dyes can leave your hair with a greenish tint due to the chemicals reacting with your hair's enzymes. The green tint generally appears immediately after dying your hair with a commercial hair dye product. The tint is unattractive and frustrating. You don't have to reapply dye to your hair or consult with a hairdresser. You can get the green out of your hair using a homemade solution.
Mix ½ cup of baking soda and 125 g (1 cup) of regular shampoo in a plastic container or bowl.
Use a spoon to stir the mixture into a paste.
Apply the paste to your hair. Let it sit for five minutes.
Rinse the paste from your hair thoroughly with cold water.
Wash your hair with shampoo and then condition it.
Effervescent tablet mixture
Place two effervescent tablets and 158 ml (2/3 cup) of cold water in a plastic container or bowl. The tablets will dissolve automatically.
Add 1 tbsp of baby shampoo to the plastic container or bowl. Stir the mixture with a spoon.
Apply the mixture to your hair. Let it sit for five minutes.
Rinse the mixture from your hair thoroughly with warm water. Wash your hair with regular shampoo and then condition it.
Note, a portion, if not all, of the dye in your hair will be removed along with the green tint.
