How can you make your hair grow longer?

Allie asked:

Okay. So a few months ago, I cut my hair really short, like around the tops of my shoulders, where as my normal hair would be down to about my ribcage. Now that my hair’s been growing for a while, it’s gotten to be about my chest length. I REALLY want my long hair again by the time school starts… Does anybody know any good home remedies or tips? I know your hair will grow fast if you trim it frequently, but lately i’ve been looking at daily vitamin pills to give my hair (and nails) a boost in growth speed. Do you have to have a prescription for nature’s Bounty: Hair, Nails, & Skin Vitamins???? If not, can you just pick them up at Walgreens or something? Are there medical risks?
HELP ME. MY HAIR IS SO AGGRAVATING.
