I really missed my thick hair, my hair now is thin I always had thick hair all my life I just don't know what happened to it in the last few months since it started falling off. I have been taking few vitamins consistently everyday for the last two months. I'm taking GNC ultranourish, PP biotin 5000 mg, MSM 1000 amino fuel liquid and biosil. I haven't been coloring my hair as I used to do. What can I do to thicken my hair what I'm I missing in my regimen please tell me. I need the thickness more than the length, for me long thin hair is not that good.
