Hi Dr Rassman,
Ive been reading your blog daily for a short while now, and im curious, if you were to look at someone how would you know if they had dupa, what are the symptoms that you would be able to diagnose that with?
Diffuse unpatterned alopecia (DUPA) is a condition where miniaturization is present all over the head, even in the areas that hair transplant surgeons think is sacred (the back and sides of the head). Thinning in the donor area where there was no thinning before, would make me suspicious of DUPA. You should get your hair mapped out for miniaturization and that would clearly give you the diagnosis.
