Growing up I always heard of Geritol, I always thought it was for the elderly, but recently I've heard that it has great benefits for hair growth and thickness. I tried it for one months and I'm a true believer. After 3 weeks my hair started growing, I would say 2.5 inches. I ordered 2 more bottles and told my friend as she is losing her hair from lupus. I don't take pills often but thought I'd try this. It was more than a pleasant surprise. Try it, I would love to hear about your results. I guess my body was lacking b-vitamins and have always been iron deficient. I'm trying one more month after being off it for three weeks just to be sure the results are real.
