I’ve been doing some research on this, but haven’t been able to find the answer anywhere. When you have a second hair transplant, do you receive multiple scars or does the hair restoration physician “overlap” the old one, removing it entirely along with the second strip?
If the previous donor hair was taken in a much lower position on the scalp than is the usual case (NOT a common occurrence), it may not be prudent to attempt to remove the first donor scar as the re-occurrence rate and/or development of an even wider scar in that area is a very real possibility.
In general, amongst experienced hair restoration surgeons who are current in their techniques, there should be fairly small variability in the size and location of donor hair chosen, and thus the residual scars, so that the salient points brought up by hair loss forum member “tofueornottofue” should be the rare occasion.
Also, then, as he points out, most hair transplant surgeons will remove the previous donor scar so that at any one time, only one minimal scar is present.
Hope that helps,
