I always had a very heavy head of hair and thick eyebrows until about two monts ago. one eyebrow is gone and the other is gone in places. the hair on the top of my head is getting very thin i am 75 years my father died after his 93rd birthday and he had a full head of hair as did my mother. what could be causing this?
Be sure that you are healthy and do not have some early manifestation of some progressing medical problem. Sometimes, hair loss is an early sign of something going wrong. If I assume that it is not a medical problem, then Propecia may work to stop the process, if the hair loss is genetic with very late on-set balding. I have seen this late on-set balding in some 60 and 70 year old men, although it is very rare to commence at your age.
