Hair lengthener

I have a friend who told me about this site she swears by it. http://www.robinanthony.com/hair-growth.html

I had a friend who swore using hemp oil made her and her daughter's hair grow long. You can buy some in the hair color section at the store, usually it's by the black woman's hair care products. She said only use a little bit though. So I tried it, guess I used too much because it took a few washings to get it out lol, was real thick gel stuff. I ended up not using it anymore, but like I said, she swore it worked....little bit though :)
