Resolved Question: should I be mixing these vitamins?

Im 21 and I weigh 117lbs I want to grow my hair faster, and I just want to be healthier, I dont drink soda or eat fast food. I drink wulong tea all the time, and pure green tea! I also put tofu into shakes with soy milk and fruit! I take fish oil, and ALIVE its a multi vitamin! can I also incorporate prenatals or would that be too much?? I just heard they make your hair grow faster!
