Hairline Advancement

I am a 56-year-old male and had a hair transplant years ago.  The scar from the previous procedure never healed well and I was wondering if it would be possible to do anything to repair it.  How would this be done and what sort of result can I expect?

I am looking to have some work done on my hairline. I am very concerned about having a natural-looking result. I can look at pictures of guys who had hair transplants and say this one has a natural hairline or this one does not but how is this achieved? What are the characteristics that make up a natural hairline and how is this achieved through surgery?

Dr epstein. you are so pessimistic!
