If Hair Regrowth Occurs from Medication, Does it Start Thin and Get Thicker?

So if I start a new regimen and regrowth occurs would it start out as thin hairs then gradually grow thicker and thicker? Kinda like a reverse minituarization?

When we talk about hair regrowth, we are talking about two different phenomena:

1. The growth of new hair that was not there prior to the use of the medications
2. The thickening of the miniaturized hairs that will make the hairs that are there, thicker

The studies on hair regrowth usually refer to hair counts that show more hair numbers after 9 or so months, but the reality is that much of the fullness that is created by medications like Propecia, actually reflects the thickening of hair shafts. I can see this when I compare the metric I get examining hair a year apart with the microscopic miniaturization mapping of the hair that I do in most patients.
