If dht causes hair to miniaturize, then propecia should help keep all my hair even slow the progress from a teenage to a mature hairline right? This is my favorite topic because I dont see how a Norwood 7 is not just a more mature hairline. Its all hairloss from hair miniaturizing so anyone that lost so much as 1 hair that thinned means they had some degree of balding yet this is not on the norwood charts.
