I am under the impression that it takes some time for the hair follicles to be damaged to the point where even when off cycle they will not work properly. For example even if you shed a ton of hair on a 2 weeks of test use if you stop the cycle it will come back assuming that it was lost from the AAS not just your age and genetic predisposition. So therefor like in my case where I started the finasteride early on in my cycle it will indirectly contribute to hair regrowth as it meant I could continue my cycle without having to worry about the testosterone converting to DHT. Also if the statistics on the Propecia site are even remotely accurate people directly get hair regrowth on it.
Some study results:

(Keep in mind these facts mainly relate to non AAS induced hair loss, I personaly believe that results would if anything be better for those who lost haor from AAS use)
•2 out of 3 men who took PROPECIA regrew hair, as measured by hair count. All of the men in the study who were not taking PROPECIA lost hair.
•A majority of men who took PROPECIA were rated as improved by doctors—77% (210 of 271) vs 15% (2 of 13) of men who took a placebo.
•A majority of men who took PROPECIA reported that their bald spot got smaller, their hair loss slowed down, and the appearance of their hair improved.
