State-of-the-art should produce two results: a natural appearance and undetectability. Hair grafts should grow without visible evidence of surgery to the casual observer (See photo below left: illustration of a transplanted hairline.) Older techniques and certain major scalp procedures cannot produce these results. Also important are the donor scars; donor scars should be almost imperceptible. (See photo below right: donor scar illustration.) A properly designed hairline and transplant pattern will still look good several decades after surgery.
