What can i do about my green hair?

I put a temporary hair color in my hair and it turned green, what can I do

Well I am pretty sure you use a light colour for it to turn green... all you need to do is go get some darker dye... but if I were you I would go buy some dye strip from sally's beauty supply. Its strips any dye from your natural colour. Hope this helps you!;p

you're lucky its just a temporary colour. I put a permanent black/blue in last weekend just on my underneath bits and it went really blue, then i wanted it out and panicked because I knew how hard it was going to be to go back to blonde from dark blue. I managed it though and am happy to say Im all blonde again.
If your hair was blonde,I suggest buying a really intense blonde lightening colour,thats what worked for me OR because it was just a temporary colour, keep washing your hair constantly and it will gradually fade. If you dont want to put a permanent colour in to correct it maybe you should go to your local hairdresser and ask them for advice. be patient, you wont be green forever, good luck !!

do swim a lot? if so u can get special swimming shampoos.
