Thank you for the time and effort you put into answering all of our questions. My question regards scarring. I have heard some people say that scar tissue forms where the hairs are implanted during a transplant, and that this can result in bumps or raised spots on the hairline. Is this true? If so, is it common? If not, why don’t scars form where the hairs are implanted? After all, a wound of sorts must be made to implant the hair, so how would do you prevent hundreds or thousands of scars from forming after a hair transplant?
With the technique we pioneered, we do two things that minimize recipient site scarring —
- We make very small wounds in the skin, essentially slits that approximate the size of the grafts. These heal very fast.
- When preparing the grafts for implantation, we cut off the skin disk at the skin level. To minimize the skin disk, we remove the top layer of the graft skin from the surface of the graft. This prevents the skin from surviving the transplant which could, in some individuals, produce the bump seen in recipient areas. The same process is done with grafts taken from strip surgery.
When doctors use grafts that have a larger surface area than what I described above, the bumps you referenced get more prominent. We have seen from the old days when plugs were done and the graft sizes ranged from 3-5 mm across, the skin always was deformed. Clearly the more skin that survives at the top of the graft, the more detectable will be the existence of the transplanted graft.
