Last January I had a very traumatic event in my life and my hair began falling out with the little white balls on the end. I thought this was due to what was going on at the time, however my hair continues to fall out. I have always had very thick hair and now it is very thin. My scalp tingles and then I stress even more. For the past four years I have lifted weights faithfully and did cardio - and even kept a log of my exercise and diet - but I refuse to lose weight - and will actually gain when I am most faithful. Could this be the thyroid, or is it a continuation of the event that occured in January - which is still ongoing, just not as critical at the moment?
