I had the thinning hair problem. I can't tell you what caused it but once I started B12 it stopped thinning and started filling in again. When I started the B12 I was taking aloe, digestive enzymes and OPC-3 daily. I don't know if it was the B12 or a combination of the products. After the research I've been doing with the products, I do believe my hair started thinning when my digestion problems began. Once I had those under control and added the B12 I started to notice the changes! Hope this helps!
