Have to agree with what others have already said. You should have started treatment earlier if you think you can get back to Norwood 2. I think you have the following options:
1. Accept it and do nothing. Easier said than done I know, but still a realistic option.
2. Buzz it down and focus on other parts in your life that you can improve. Personally I think that with the amount of hairloss you have it would look better if buzzed completely down since your hairline give little to no facial frame.
3. Hair system. As others say you can get a good head of hair. Only realistic option for you if you think good hair and anything above norwoord 3/4V.
4. Agressive regiment to get back as much as possible: Dutasteride, keto and minoxidil two times per day. Need to do this for minimum 1 year and prefereably 2 years to see how you respond. Then maybe a hairtransplant for the hairline combined with SMP. Will still need to keep a short buzz cut, but should give you some frame to the face.
Regardless of what you decide we might get more options in the future like shisedio and Tsjui+++++, but if you read threads back from 10 years ago the waiting game has not paid off.
