Is there a link between past accutane use and DUPA? I took accutane when I was 17 and again at 22 for cystic acne. My hair started thinning at 23 and now at age 30, I was told by a doctor I have DUPA. If not the accutane, then maybe the DUPA is linked to the same reason I have had cystic acne for 15 years?
Anything is a possibility, but I doubt there are real causation relationships at play here. One may postulate that Accutane produced more diffuse hair loss mimicking DUPA (diffuse unpatterned alopecia), but you are trying to find answers and explanations to a problem and your guess is as good as mine. DUPA is not related to Accutane use to my knowledge, nor, I believe, that acne is related to hair loss.
