finasteride is doing well I think. I'm in a shedding phase at the moment so Im looking less dense than usual, but I hear a shed is a good sign and typically ends after a bit and it grows in thicker(when using both finasteride and minoxidil).
On the rogain and finasteride together point. You know which is working, because both are (if they do) finasteride works to maintain, and rogaine is for regrowth. Almost every success story on these boards have some combo of finasteride and minoxidil (and sometimes some extras) Im not a scientist, so I don't know why but that combo is the best it seems.
I have hair so long its halfway down my back, I know applying minoxidil is suk, so I recommend for best results use rogain foam 5% minoxidil and wait 15 minutes and run a cheapo black comb through your hair, and it will look awesome.
