Scar wasn't a big concern of mine; I don't keep my hair super short and I'm sure I'll need a future surgery, so this scar will probably come and go. That's not to say I was negligent but I think I could have done a little better. That being said, I think once a Dr. has his proven technique, the rest depends on the patients physiology and overdoing it too soon.
This Saturday I had some pictures taken to see how my scar is healing and I have to say I'm impressed/lucky. Most of the pink is gone, there's hair growing all throughout, and aside from a couple small spots, its super super thin. I only used vitamin C oil on the donor site once so more than anything I think its how well the patient heals.
