Efficacy of propecia (finasteride) and time before seeing its effect on hair loss

How long does it take before judging the efficacy of Propecia (Finasteride) on hair loss?

It is very important to be patient when you use Finasteride. Indeed, its action is often delayed in time and, moreover, it is often discreet. You generally have to wait a few weeks before observing a slowdown in hair loss (between 5 and 6 months). The action is all the more difficult to observe as the average hair loss amounts to one hundred hairs per day. Very often, the action of Finasteride is observed a contrario, that is to say when the patient stops using it: at that moment, a larger hair loss than the initial one occurs.
