Hair Formula 37

I don't know if this was answered because I haven't been here in a while, but has anyone tried HF37? I was going to buy it but I see there are so many other hair vitamins that are way cheaper. I want to know I am getting my money's worth. Forty four bucks is a lot for only a month's supply of vitamins. I am in college. I don't think I have that kind of money to get those pills every month. Someone give me some feedback, please.
