DPA vs MPB

I have a question regarding Diffuse Patterned Alopecia (DPA). My hair loss follows this diffuse pattern, with no loss on sides and back. I was wondering is the success rate for DUA treatment with propecia the same as typical norwood pattern hair loss? Also does DPA typically progress more rapidly than norwood patterns?

If the sides and back are not miniaturized, then you may have a form of MPB, which in young men responds usually very well to Propecia (finasteride). Diffuse unpatterned alopecia (DUPA) usually does not respond to finasteride, but a rare few cases I have seen have gone against the grain and responded to lessen the amount of miniaturization, although some of it did remain. DUPA is essentially not treatable and we really do not understand what is happening in those who have it.

On the other hand, with diffuse patterned alopecia (DPA), this is a form of male patterned balding that is genetic and can be effectively treated with finasteride. The presentation is more generalized in the pattern of balding and rather than lose hair from the front to the back in a progressive manner, the hair loss is subtle and generalized, but ends up at the same point as if it were classic patterned balding.
