I have bumps on my hairline after the transplant, why is it there and what can I do about it? (photo)

These bumps may be caused by too much skin on the grafts or grafts may not have been placed flat and flush with the surrounding skin at the time of the transplant. A repeat transplant with single hair grafts that have the skin trimmed off and placed flush will overwhelm the problem and address much of it, but it will still be there.
