It's almost time for a haircut.

I agree with Bacon and Myles. Don't dye it, since that usually ends horribly, and work on layering it. In general I think cutting it shorter than now is definitely a must (though it will feel weird for a while, of course; embrace that, since that's what I did with my hair and ended up loving it), with special focus on the bangs. Your bangs are very good, but I think it's time to cut them when they have to be curled behind your glasses lest they blind you.
