I turned my bathroom into a chemistry lab and tried every cure I could find on the internet.
Here are my findings:
Lemon juice - removes maybe 2% of the colour
Mayonnaise - useless and smelly
Ketchup / tomatoe paste - Kinda works, but I think you would have to repeat the process 10 times to get rid of everything.
Baking Soda - Didn't do anything
Vinegar - Not much difference, but my hair did feel good after.
Baking soda and then add vinegar on top - AMAZING. It took 90% of the colour out my hair. When I added the vinegar, the baking soda literally fizzled and I think this reaction is what sucked out all the green.
Note: This worked for me, but please be careful if you try anything I have suggested as I was fully aware that my hair might all fall out and am kinda thanking my lucky stars at the moment.
