The test area used in the 5 year propecia study is a one inch diameter circle. Which means the area is (.5^2)(3.14) = .785 square inches. The average density of human hair is 2,200 hairs per square inch. That means the average hair density in the propecia studies was around 2200*.785 = 1,727 hairs. I'm assuming the Dutasteride studies conducted for hairloss used the same test area (is this wrong?). This means when comparing hair counts at different dosages, there were very minor differences of 15 hairs in the test area. Is it safe to assume that a 15 hair difference in an area of 1,727 hairs is just not worth the extra dosage? Heck, is a 100 hair difference not worth the dosage?
Basically, what is the average hair density of a balding man compared to a non-balding man in a test area such as the crown let's say? Half of normal? In that case, would a 100 hair difference be significant? The point of this is to see if higher dosages of dutasteride (2.5 mg +) are worth it.
