Are You Born With DUPA?

dear doctor,
Im a male. I was wondering if you can get DUPA at a later age like mid 30s or is it something that your born with? thank you

I believe that diffuse unpatterned alopecia (DUPA) can appear at any age and there is probably a genetic predisposition to it. We do not know the cause of DUPA, but we assume it is like the female unpatterned hair loss… which we also do not understand.
