How can I make my hair grow faster? 10 PTS?

I got a terrible haircut that’s way too short, I need to grow my hair out FAST…do you know of any good methods to make my hair grow faster? It’d be nice if these methods didn’t involve any expensive or unnatural products or anything. Thanks(:
I also heard that horse shampoo helps your hair grow faster…any thoughts on this??
