I have been on finasteride for 3 months. I feel like my hair has darkened up a bit,but It feels like the corners are moving back and im approaching norwood 2 territory.
It does appear that you are heading towards a NW2 with a "perforated" area of miniaturization along the hairline (mostly temples). This may be considered maturation, however it might lead to balding. Don't know for sure.
