ROGAINE® products stimulate hair follicles to shift from the resting phase to the growth phase. Thus, it is not uncommon to see a temporary increase in shedding during the first 2 weeks using ROGAINE® products. This occurs in some people as the new hair pushes out the older hairs, when the hair follicle shifts into the growth phase. It is very much like losing baby teeth to make room for adult teeth. This increase in shedding is only temporary and should subside within a couple of weeks with continued treatment. Please note, however, if increased shedding continues for longer than 2 weeks, you should consult your doctor to rule out other possible medical problems.
