My hairloss started quite suddenly a few months ago and initially my Dr thought TE due to psychological and emotional trauma. I have got PCOS, at least 2 years ago I was told I had it after a year with no period, hormone tests and an ultrasound. I've always been quite hairy all over, fair really and very few coarse, no facial hair. The thing is since then I have had perfect periods for the last year and a half, can't fault them and can time them to the day. I recently had back new hormone results and they have come back normal too. I had worried that my PCOS was maybe at fault, am I right in thinking it would be higher testosterone that causes hair loss in women? My Doctor is useless and getting in to see him, or anyone else takes a good couple of weeks! I also get the impression I know alot more than he does! Also does PCOS related hair loss come on suddenly like this?
