I'm female, in my early 30's, no children, taking birth control pills for ~5 years. For the past two years, I have noticed my hair thinning a great deal, especially in the front. I have heard that hair loss can indicate vitamin and mineral deficiencies. Can anyone give me more information about this, or recommend supplements I might try to stop or reverse this? Or, if there's a forum that might be better suited to this question, I would appreciate being directed there.
