What finasteride does, month by month
The published course of finasteride on a single linear month axis: DHT falls within a day, nothing is visible for three to six months, and results build to a maximum between twelve and twenty-four. The shaded stretch is the period in which the treatment is working and cannot be seen, which is when people stop. Proportions are of men in the cited studies, not a forecast for any individual.
