1) Are you male or female? 2) Is there any patch forming? If so (and you are male), is a 'normal' looking patch? If it is (and you are male), could be just male pattern baldness starting. I started losing my hair in odd patches a couple of years ago and according to the consultant at hospital this is due to non specific alopecia. Usual cause is stress (though I don't think I'm too stressed). Consultant said it might come back, but probably wouldn't and that as the only real treatment is by using steroids, they don't usually bother treating men, as the side effects are worse than the baldness. I am not too bothered about it, so thats OK. However, as women are more worried about their hair falling out, then it is usually treated with steroids. You might not have alopecia, but thought I would mention it.
