My hair has started to thin due to PCOS. I decided to give this a try because I love the thick full hair that I had and I'm trying to get it back. Since I have started taking it I can already tell that my hair is growing faster. I'm hoping that I will be able to see more change as I keep taking this because it is becoming a lifesaver for my hair right now. This is available on Amazon . I received this at a discounted rate in exchange for a honest review.
