the fact that fidia only used 40-50 year olds subjects in the rial is very suspicious, i would imagine the thinking was that if they had young guys who didnt maintain they couldn't market it as anti fall lotion. Essentially it looks like they played it safe by using older guys with probably much slower hairloss. Hope im wrong of course but it looks like they didnt want to risk the trial by using young guys with aggressive loss.
This study is not established fact. Just saying. This is how the rumor mill stays perpetuated. It should be clear that you’re saying “if” Fidia only used 40/50-year-olds
