You're too young and not bald enough, so not a candidate.
If you were to do it, don't do it in the UK, that would be a huge mistake.
Well I really hope I can find someone. If anyone knows a hair surgeon/clinic that will restore NW2 -> straight NW1 at 22 yrs old, please let me know.
It is impossible to say if they can or can't without seeing photos, there are people who have had hair transplant's in your situation. What you seem to want is a hairline hair transplant, and yes there are clinics that do those. At 22 though you are taking a big risk if you decide to do it.
If finasteride works, then maybe I won't need another transplant for decades.
