Want to post a picture of the spot on your head?
This may sound really odd but I know a bunch of body modification pros who specialize in scarification and flesh removals, if you're not scared away yet let me say that maybe its possible that the spot can be pulled closer together so when you grow your hair out, its not nearly as noticeable.
My point is, you could talk to a plastic surgeon and see what your options are. I have no experience with hair transplants but from the guys I know who have had them, they were not worth it in the end. You should know coming to SBG everyone is going to advocate shaving it all off but if thats not your thing and you really want to do something about it, talk to someone who knows about scars, not someone who makes money off of dudes losing their hair.
