About 2 months ago I used a dark brown hair dye just for a change. Most of the colour has now gone and I want to know when it will be safe to use Sun-In again? I used to use Sun-In regularly. I know people say it's not good for your hair, but I've never had any problems. I don't want my hair to go green - or even worse: ginger!!
It is quite likely to go ginger - mine did when I experimented with it as a teenager! I had to go straight to the hairdresser to get it fixed, and like others have told you, it does ruin your hair!
I worked with a girl who used it (not even that muc) and her hair crumbled away cos sun in is so harsh!
Go to the hairdressers, explain about the dye, and get some proper highlights done!
