I had my incision at the hairline and a hairline advancement by 2,5cm with a small brow lift ( and forehead, nose, chin job). The scar is barely visible and can be covered by some hair transplants. There are some hairs growing on the scar already. I think it is a better solution than having a coronal incision for most of us. The coronar incision will almost always to a higher hairline.
