Actually, trimming your hair is supposed to help it grow faster, or atleast make it appear that way.
Why? Because when you have hair with split ends, the ends will keep breaking off, so even if your hair is growing, it'll be hard to tell O.o;
So it's basically recommened to trim your hair atleast every 3 months.
But other than that I am currently taking Nioxin Intensive Therapy dietary supplement. There was a thread floating around here on the topic of "Nioxin" and someone mentioned that the Nioxin Intensive Therapy dietary supplements helped their hair to grow faster... Don't know if its true yet seeing I've only been on it for a few days now.
Anyways, I think you look beautiful with your hair cut

! It suits you really well.
what about um. hair loss..what can u do to fix that?
Are you under a lot of stress right now? (Like for finals?) Coz that's supposed to make you lose your hair a lot. Or it could be a result of an inadequate diet.
I heard things with omega-3 fatty acids (Fish is a good source of them. I'm currently on fish oil pills xD) and I'm also using Nioxin Intensive Therapy products atm. It's actually helping, and my hair is still falling out little by little, but noticeably less.

Beside that you can try take loads of vitamins/minerals~
