Work looks fine i agree and should produce a nice result. I agree having a HT at 17 is very risky as you just don't have any idea how your loss will progress and most clinics wouldn't operate on people so young unless there was a very good reason to do so.
On the plus side it's good you have chosen a more conservative hairline than most young people would probably want, this is wise considering your age.
Are you on any meds to help with your loss down the line?
What do you mean by when your were 15 you had to go full bald?
Thanks for sharing
