Visible difference, the "island" isn´t isolated as before. You might add some Rogaine foam to get a bit of that hairline back.
About your Norwood: There is no way you are 2, you are a 3.5. If you are lucky you might go back to a Norwood 2.5 with treatments, the rest would require a hair transplant.
Btw. Are you sure you are only balding for 3 years? Damn, it is really agressive particularly since it started at a rather late age compared to many other forum members.
Good Luck with your hair!
