Unfortunately, your hair isn't going to grow with split ends. They'll just keep splitting further and further up the hair shaft.

I know it can be hard, when you're a teen to have hair that's different than other people wear. Believe me, I know, and still remember the lengths I went to to try to make my hair look "right."

Is there any chance of having your hair cut by someone who uses the Deva method, or otherwise specializes in naturally curly hair? That's really made a huge difference in how my hair behaves, even though it's in that awkward stage that seems to last forever. Because it's shaped to compliment my face and bring out the best in what my hair does naturally, it really looks tremendously different, and I feel much better about it than I ever have with it this length, which is very similar to what you're describing yours would be.
