How to counteract green hair dye

Updated April 17, 2017

When attempting to correct or counteract hair-colour disasters, the most obvious solutions should be avoided. Simply colouring over green dye with brown hair colour results in greenish-brown hair. You cannot cover over a colour mistake; you must correct it or counteract it. Colours are corrected or counteracted by colours found on the opposite side of the colour wheel. Red counteracts green and vice versa. In order to turn green hair into something more appealing, you will need to add red to the hair using a combination of colour and colour additions.

Open the colour bottle and set it on a level surface. Pour 60 ml (2 oz) of colour into the bottle along with 60 ml (2 oz) of 10-volume developer and 15 ml (1/2 oz) of red colour addition. Replace the lid and shake to mix. Put on the gloves.

Begin with clean, dry hair. Apply colour to the green sections of hair first by squeezing the colour onto the hair and working the colour in with your fingers. Finish applying colour to the rest of the hair until the hair is thoroughly saturated from root to tip. Mix additional colour as necessary.

Set a timer for 30 minutes. Flush out and clean the colour bottle with a steady stream of hot water from the faucet. Clean up any colour drops and messes created during the application using a damp towel. Store non-mixed colour supplies in a dry, temperate storage cabinet.

Rinse the hair with warm water until the water runs clear. Shampoo the hair in order to remove any remaining colour residue. Condition the hair, towel dry and style.


Colour selection is vital to colour correction. Be sure to choose a colour that is the same level or darkness as your green hair. If you wish to go lighter, you will need to pre-lighten your hair and apply colour in a two-step process. You should also be careful to choose a colour possessing the right tonal quality. In this case, look for red-based colours. Red-based colours are not necessarily red in colour. Many blonde and brown hair colours possess red bases.
