Hi Aaron,
Before rushing into another surgery at such a young age, I really would wait and just see how things turn out with the scar.....I know it is easier said than done, but the very worst thing you can do with your hair is act out of desperation.
You may also be seeing things which other people are not, and it may not be as bad as you think. If you post a couple of photos here you will get some honest feedback from good people.
