DUPA and Propecia

hello i have Diffuse Unpatterned Alopecia (DUPA) and was wondering if propecia worked for me would it thinken the existing hair or would it have to shed and grow again as a new hair? and if possible could you tell me how long i’d have to wait to see if the propecia was working for me?

Propecia works by blocking DHT effects on scalp hair that is affected by male pattern hair loss (androgenic hair loss). Hair loss from DUPA (diffuse unpatterned alopecia) is not related to male pattern hair loss and it may not be affected by DHT. Thus, Propecia may not work, but it is the only drug that can be used. That being said, some doctors (include me in this group) will prescribe Propecia to patients with DUPA in case there is an underlying androgenic component to hair loss. In some patients with DUPA, I have seen improvement with Propecia.
