i recently have had some fue into a scar in my hairline. It has been 6 months and approximately 60 % of the hair has grown back. I plan on doing another fue procedure in 6 months from now. My question is how many transplants can be done into a scar? I am not sure if the density of hair in the scar will ever match the density of my surrounding hair but i will try.
There is no specific limit to an FUE (follicular unit extraction) session, other than the supply of hair you have left (and the skills of the doctor / surgical staff). As long as there is enough supply and an area (such as your scar) that require more hair, you can have the FUE procedure. As a rule of thumb after only 6 months out, you may not have all the transplanted hairs grown out (some may still be dormant). I would wait at least 10 months before having another procedure in the same area.
