You and your hair are both so pretty! Gorgeous curls!
I think food has a lot to do with hair growth. If your diet has a considerate amount of calcium (milk, yogurt, cheese) you should have a little faster growth (and stronger hair) than those who don't get too much calcium. I know many people take vitamin supplements to encourage growth. In the long hair website the ladies swear by castor oil too. I only use it on my lashes and I can tell you that it does stimulate growth. I haven't tried it on my scalp though (on a regular basis). I think I'm going to start doing it twice a week and I will let you know the results.
