Hair Loss in Women?

I know that when women age there is a tendency for their hair to thin, but I have a friend whose hair is thinning excessively. She is 54.
It occurred to me that she may have a vitamin deficiency. What lack of vitamin would cause this in women, men, or rats?
Also. I plan to suggest that she go to a dermatologist & discuss the matter with him.
Does anyone have any thoughts or suggestions on this matter?

AM might be an unusual place to ask for medical advice, but I know there are some very smart people on this site.

Thanks,
