I have been loosing tons of hair and eyebrows for the last 2 years. example I lost over 50 hairs just brushing this morning. I have been tested for thyroid conditions and have been slightly hypo. I have been on synthroid for 1 year now and my levels are fine. I went to several hair specialists and derms and they tell me my hair looks fine and send me on my way. My head burns and itches but shows no signs of any skin disorder, per all docs. I have a script of propecia and am ready to start today. i read about the sheds you might have I also read about the burning and itching which I have in spades. Since Im loosing so much hair already, thin and thick, I guess I might start it. How soon do most guys notice the shed. My loss is diffuse over my entire head, back, ect. but my temples have taken the worst of it. The Doctor in pittsburgh told me I have mild adrogenetic alopecia and I did not need to take propecia, that Im 37 and it happens!! Great, he was bald anyway. I know counting hairs is not a good thing and helps nothing but its hard to stop looking when every time u touch ur head hair falls out. when my hair is wet it looks like sh*t. Anyway Im hoping this pill will stop the hairfall and especially the burning. any advise
