These are elevated grafts (photo on the left). The surgeon that put them in used a Choi or Lyon Implanter and left the upper part of the graft sticking out. This is not the way I do it for many reasons including:
1- You have to wear a hat for weeks after the surgery and can’t be normal
2- It may leave cobblestonning of the skin as the skin from the grafts lived and may remain elevated
3- It is not undetectable short or long term. Look at my patient to the right of your picture which is one day after the hair transplant. No cobbled grafts seen.
