14.5 months on Fin, what the hell is going on?

Hey guys, been on fin 0.5 ED for the past 14 months, been shedding constantly since the second month so bumped my dosage up to 1mg ED in the last few weeks to see what happens. Since the shed began my overall density has gone off a cliff edge: my top, sides and back have all thinned out considerably and are showing no signs of stopping. However, although the density of my forelock is in tatters, the actual position of my hairline doesn't appear to have shifted much, and it seems from the pictures that there may be more small hairs growing there compared to baseline, so what's going on? Is this just further miniaturisation or could it be the beginning of some regrowth? Very confused and have been strongly considering dropping Fin as I wasn't shedding prior to starting it and I've lost a serious amount of hair since, but seeing these pictures side by side has given me pause for thought.
