How can I make my hair grow faster?

I got my hair trimmed and I really wanna grow my hair out. I'm using sunsilk longer and stronger s/c every other day, the day I don't wash my hair I use a leave in conditioner, I'm using loreal fiberceutic deep conditioner once a week and I'm going to try and buy swisse hair skin and nails vitamins. I'm also drinking 5 glasses of water a day. How fast will my hair grow? What can I do to increase growth? Thankyou :)
