Thanks for the insight guys, very interesting. Yes I should have mentioned I'm using 5% Foam (Kirkland).
The graph is rather surprising, I don't recall ever seeing that before. I'd be interested in hearing more about this study.
I did consider oral Minox, though at my current age (66) I was concerned with side effects.
Just curious, has the group found any one particular product works better than others ? So far I've used Kirkland, though I just started ELEVATE 5% Minoxidil Foam (less expensive). But I can't speak to that as it's only been a few days.
