You’ve mentioned the condition Diffuse Unpatterned Alopecia (DUPA) as being the miniturizing and loss of hair on the sides and donor zone, and that your pretty much screwed if you got it.
What I want to know is if (DUPA) is a stable condition or is it a progressive condition, meaning will a person with (DUPA) eventually lose all his donor hair or will it just become thin and stay thin?
DUPA can be stable once it appears… or it can be progressive. The other day I met with a young man who clearly had DUPA a year ago with 50% miniaturization in the donor area. When he came in this time after being on Propecia (finasteride) for a year, the miniaturization rate was down to 10% (a figure I’d call normal). Successful treatment for DUPA with finasteride is in the minority of patients I see, but his hair loss needs reflected a Norwood Class 3 pattern, so he might become a candidate for FUE if the process remains stable.
