I was having some serious hair loss issues. I would get out of the shower and brush my hair and so much would fall out. It was very upsetting. My brush, after just one brushing, would look like I hadn't cleaned it in six months - that's how much hair I was losing. Then I found Natrol Biotin and started using it with 

I only used it three times and my doctor was looking in my mouth and she goes, it looks like you whiten your teeth, so it must be making a difference. I need to use it more though. At first my gums were sensitive so I only used it every few days but I think they are getting used to it now so I wanna increase it so I can have my teeth at their whitest hopefully.

This notebook is not a good buy. I bought two, one for each kid. It is very slow, pixely, and you have to touch it many times before it responds. I want to send them back if possible.
