Yes, there are lots of scars in the recipient area. Every time your skin is pierced or cut in ANY WAY, there is a healing process (think of a knife wound). This healing process entails extra fast cellular growth, but does not include melanocyte growth as well. The new skin loses the ability to pigment itself. It will be very white.
http://hairtransplantnetwork.com/Share- ... ToS=repair That page has several pictures of hairtransplant repairs. If you look close, you will see the "white dots' UNDER EACH AND EVERY TRANSPLANTED PLUG. If you get dense work, youre whole scalp will turn quite white because almost all of it will be scar tissue. If you get undense work, you have a head full of polka dots that are white against your pinkish scalp skin. The scar in the back of the head is a linear one, usually about the witth of a straw. It might go from almost ear to ear. It will be very white. You will never buzz your head again after a big transplant. Some docs will transplant hair back into the donor scar though.....and it will mitigate the appearance by the hair's presence there.
On buzzing your head after transplants though...........if you shave them, you can see the hair underneath because scalp skin is much thinner than beard skin. They look like grey dots under the scalp skin. Its not like getting a close shave on your face. The dots are there for the world to see too. SO a guy would have to get a skin-colored tatoo on his head or wear makeup on his scalp if he wanted to shave his transplants.
http://forhair.com/fue_hair_restoration_results.html Those are pics of a real state of the art transplant by a good professional surgeon, Cole. If you look, you see all the tiny holes he made in the donor area (this is not a strip scar surgery). There will be small white scars around them, but they wont be very noticeable. A bigger incision is made in the recipient (front) area though. MOre noticeable. But transplants arent supposed to be worn very short though............so this guy should be OK unless he's one of the people whose hippocratic wreath was slated to thin.
HM phase 2 trials are set to start this summer by the way.
