I've been thinking about having long hair for three years, but never got a chance to grow it out. due to the pressure from my high school ( a private religious school) and some of my friends (who always think short spiky hair is cool), i always got my hair cut back to spiky during the growing progress. Finally, i got the chance to have my hair grow out in Feb, now the front is about 4" long, but the side is still very short, since i almost shaved the side. My dream length is about 1 or 2" below my shoulder, don't know how long it's gonna take. And I started taking Biotin and Fo-ti at the same time, 1000 mcg of biotin and 1 capsule of Fo-ti in the morning (usually before breakfast), and 500 mcg biotin and 1 Fo-ti at night (around 9pm). The guy from the vitamine store said that the Biotin and Fo-ti would only make my hair stronger but doesn't have anything to do with the growing rate. The only way to make my hair grow faster is to take "Metabolife", which is a kind of Diet pill that increase the speed of metabolism in my body. And meanwhile, the multi-vitamine will make the hair sleek and strong. Well, this is just my personal experience and I don't know the result either, so wish me luck :P
