The whorl pattern, the surface area and the risk of chasing progressive loss make the crown a planning problem, not a technical one.
Hair at the crown spirals outward from a central point. Recreating that spiral with correct angles is far harder than the parallel forward flow of a hairline, and errors read as obviously artificial from behind — where you never see them and everyone else does.
The crown is a dome, so its true surface area is much larger than it looks in a photograph. Covering it densely can consume 2,500–3,500 grafts on its own — often more than the entire front.
Crown loss usually progresses. Filling it at 30 can mean a halo of transplanted hair with new balding around it at 38, requiring more grafts from a donor already partly spent.
Front first, crown later or never. If the hairline frames the face, most patients look transformed without touching the crown — and their donor reserve stays intact for the decade ahead.
Yes if donor supply allows, but we will usually recommend prioritising the front and reassessing the crown after twelve months.
