How come the more i wax, the faster my hair grows?

I always wax and i do it about every month. I don't use the leg scrubs until after my hair starts growing back because i want my legs to be smooth LOL. So why is it that my hair grows back faster?How come the more i wax, the faster my hair grows?
your body wants to make sure you can keep warm, so it grows hair out to cover your skin
