My hair grows so slow?! Is there anything I can do to make it grow quicker?

I straighten my hair so much and I know this damages my hair and causes a lot of split ends and breakages. I would stop straightening my hair - if my hair wasn't so horrible natural -.- I was wondering if there are any ways to help my hair grow a little faster? (My hair has been the same length for a year - every time it grows a bit, which could take months - i have to have a trim to cut away split ends, which takes me back to square 1.) Thanks!
