If your body eventually regulates your skin & T levels I wonder if it would also eventually regulate your DHT levels to how they were pre-finasteride by increase the 5AR enzyme production to counter the effects of finasteride?
I've been on a very strange journey as well (on both finasteride & minoxidil)! until about 7 months I didn't see much difference - some new vellus hairs around temples which looked promising.
Then started shedding from months 7-10 which was pretty scary! Then from 10-12 it started improving, possibly...
