How long does is take to grow hair?

I want to grow my hair down to my waist. Its currently down to the middle of my back. How long would it take to grow my hair this long? Is there anyway to make it grow faster?
Where would i buy prenatal pills? Couldnt i just take them instead of putting them in my shampoo?

Well what i used to do i would put my hair in a tight braid while i would sleep that caused your hair to pull and it can make it longer in a month my hair was an inch longer, i would also get prenatal pills and crush them into my shampoos but if u choose to do this avoid any other body part becuase u might start to grow hair there too also you can buy hair&nail pills they help ur hair and nails grow longer, GOOD LUCK.
