6 month on propecia + 5% minoxidil, temporary halt and shedding is back again!!

[JohnW]

Hey guys
I started my treatment using propecia + 5% minoxidil + prp about 6 month ago.
Like most people, I experienced some massive shed at the first two or three month as I was expecting after which it almost stopped. My hair improved significantly after 4 and a half month that I recieved some compliments from my friends.
I am now at month 6 and the shed is back again. I can feel the thinning of my hairline even though it had already been improved.
Is it temporary or the medication has stopped its effectiveness?
