Hair Loss & Hair Transplants

I'm going to try the prenatal vitamins (even though I don't have kids and don't plan on having a baby). I use to have really long, thick, curly hair but have noticed in the past few years that it has really thinned out and my scalp is dry and itchy at times. I was in University for 5 years which really stressed me out and I sometimes wonder if that had a lot to do with it. I think with the stress of what was going on during that period in my life, I didn't always eat 100% healthy. I did take vitamins in the beginning and stuck to a really healthy diet (I'm vegetarian) but over the years, my meals have not always been balanced. I read up on hair loss (or thinning) and know that there are a lot of factors involved so I think it takes time to figure out what might cause the problem in the first place but diet is a good place to start. As well, I looked at some prenatal vitamins and noticed that it contains the majority of good vitamins and minerals (D, B, Calcium, Magnesium, Iron, Biotin and other valuable ones). I figure that it would be cheaper to buy prenatal vitamins vs. separate vitamin bottles!
