Why the crown is the hardest area to transplant
The whorl pattern, the surface area and the risk of chasing progressive loss make the crown a planning problem, not a technical one.
The whorl problem
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.
Surface area eats grafts
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.
Chasing a moving target
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.
Our usual advice
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.
The Ones People Actually Ask.
Can the crown be done in the same session as the front?
Yes if donor supply allows, but we will usually recommend prioritising the front and reassessing the crown after twelve months.
