Wow... it's really informative. Definitely! Thanks for the info. However, for those people who've conscious on their diet or let say, find more ways.. I would suggest the one that my sister is taking right now. A supplement for having not only a healthy hair, but also skin and nails. I don't know if you heard this before, the Hair, Skin and Nails Factor. But i know it's been a popular now especially in UK. Just sharing.. ♥
