That depends. If a particular follicle had already miniaturized (from MPB) and the epiandro was it's undoing, it will likely come back worse off than before (peach fuzz consistency), or not at all. It really depends on the state of the follicle before, as well as the hormonal environment of the scalp during the dormant (telogen phase).
If, for whatever reason, a drastic hormonal fluctuation (PH/steroid use) signaled an early end to the anagen phase of a particular and otherwise healthy hair follicle, that particular follicle will likely comeback as it was before.
Time, genetics, and individual conversion to DHT will dictate individual results. Epiandro is a two-step conversion to DHT and that conversion is reversible as well. The precursors/intermediates of DHT are also active hormones, but are noted to be considerably less androgenic than DHT.
In a nutshell, if you currently suffer some degree of MPB and see hair shedding while using epiandro, some will come back as they were before and others will not. If you have no history of MPB and you shed on Epiandro (or other steroids), that hair will likely come back as it was before.
As always. YMMV! :]
