I started losing hair a couple of years ago, but have never found the cause. I'm female, in my twenties. My hair got noticeably thinner the first time I took prednisone - it started several weeks into the course of prednisone, and was fairly rapid. I had also started taking Amitriptyline, though, and when I was off prednisone and my hair was still thinning, I thought it must be from the Ami. But Ive been on Ami ever since, and though my hair hasn't gone back to normal, it's not got any thinner for a long while. So I don't know which med caused it, or if it even was a med. I don't have any nutrient deficiencies that could account for it either. Now I have thin hair, not enough to look abnormal, but enough that it's obviously far poorer quality than in photos of myself from before, and obviously thinner than the average women's hair.
It bothers me a little, but it's not one of my major concerns. The facial hair growth that prednisone caused upset me far more and I went to far greater lengths trying to fix that cosmetic problem! (The facial hair went away soon after stopping pred, but now I've started prednisone again and am not looking forward to the possibility of that side effect returning!) For a while I thought it best to stop dying my hair when it was so thin, but now I dye it regularly and it doesn't seem to harm it. I also wear head bands or head scarves sometimes if I feel a little self-conscious about it, but generally I just accept it. I'm not sure why different things bother different people, why the facial hair bothers me so much more than thinning hair on my head, we all have things that upset us.
Thyroid problems are another possible cause of abnormal hair loss that I remember coming across when reading up on it.
Also have you had your hormone levels checked? Sometimes women can lose hair in what's called "male pattern baldness" - i.e. rather than just losing hair, they lose it in the way that would be considered normal for a middle-aged/aging man, with hair on the top and front of the head falling out first. This can be caused by women having an excess of male hormones.
