You should dye your hair red or purple based on your complexion and the desired results. Some people will look better with one color or another depending on their wardrobe.
Just don't dye it till it starts to turn gray. I think red heads have the best color hair, and red is very popular right now. Ever notice that you can't get red hair dye to look natural, so keep your red hair.
re-dye your hair with a brown colour that contains a hint of red dye. this should go over the green.
She didn't dye her hair red, it was a photoshopped picture.
depending on how dark your hair is and what dye you use, you may or may not have to. if its a lighter to medium brown and the red your using is dark-ish, then you should be fine. it should show on the box what colour it'll end up like, but it chances are it wont be very bright red. if your hair is dark, the red wont be very noticable. if you want bright red, then you should bleach your hair.
