Hey, I've been using it for just about 3 months now. I'd pretty much agree with your experience except my shedding has gone from pretty drastic to minimal and I haven't noticed any loss. My hair feels better in general, better volume. Nothing drastic but it's encouraging.
I've been on oral minoxidil for a year before starting Cosmerna. The real issue for me is the quantity/ application, if it's genuinely localized and isolated to application area (which we better hope it is) how the f is one supposed to spread 1 ml over the whole scalp? I've read you can dilute with water but due to the applicator and storage, that's not the easiest thing to do in this case. So yeah, I ran out early on first bottle. That said, I've seen enough to give it at least 6 months before re-evaluating.
Good luck
