Histogen - Total Hair Count - Question

[Scientalk56]

I've heard once that Minoxidil increases hair count about 10 percent
and propecia about 20 percent

Well all know (minoxidil users) that 10 percent is ridiculous...

Whene i saw histogen last presentation i was shocked:

Important Note: histogen trial was conducted on Norwood 3-6



so can any one explain the 10 percent here? did i miss something?
