Graft count depends on the area you want to cover, the density you want, your hair calibre, and your donor supply. Very roughly, restoring a receding hairline or temples takes around 1,500-2,500 grafts; the crown takes about 1,500-3,000; and rebuilding the front third plus mid-scalp can need 3,000-5,000 or more. Thicker hair and a strong donor area achieve more coverage per graft.
These are planning estimates only — online calculators are roughly 40-60% accurate, while an in-person consultation with scalp measurement is around 90-95%. Your lifetime donor supply is limited, so a good surgeon plans for future loss too, not just today's gaps. Use the cost-and-graft estimator to get a ballpark, then get quotes from vetted clinics.

FAQ
How many grafts for a full head?
Extensive restoration (front, mid-scalp and crown) can need 5,000-7,000+ grafts, sometimes across two sessions, and depends heavily on donor supply. Most people don't need a 'full head' — they restore the areas that read as balding.
How many grafts can be done in one session?
Many clinics do 2,000-4,000 grafts in a session; very large 'mega-sessions' go higher but depend on donor density and surgeon capacity. Spreading work over sessions can protect graft survival.
