How many grafts do you need for hair transplant? Norwood stage estimates, what affects graft count and how Dr. Arslan calculates the right number.
Norwood stage to graft count — reference guide
| Norwood Stage | Hair loss pattern | Typical graft range |
|---|---|---|
| I–II | Minimal recession — early hairline change | 500–1,200 |
| III | Visible temple recession, beginning mid-scalp | 1,500–2,500 |
| III Vertex | Crown thinning beginning | 1,800–2,800 |
| IV | Significant frontal + crown loss, bridge remaining | 2,500–3,500 |
| V | Large bald area, narrow bridge | 3,000–4,500 |
| VI | Very large bald area, no bridge | 4,000–5,500 |
| VII | Most extensive — rim only | 5,000–7,000 (multi-session) |
These are averages. Individual variation is significant — a large scalp at Norwood IV may need 500 more grafts than a small scalp at the same stage.
What else affects your graft count
Hair calibre: Coarser, thicker hair covers more surface area per graft. Fine hair requires more grafts for equivalent visual density.
Target density: A 30 FU/cm² result looks natural but not dense. A 50+ FU/cm² result looks fuller. Higher density = more grafts.
Scalp size: A large bald area at Norwood IV needs more grafts than a small bald area at the same stage.
Donor density: Patients with dense donor hair can yield more grafts. Patients with thinner donor hair may have a lower safe extraction ceiling.
How Dr. Arslan calculates the right number
At Hairmedico, every consultation includes a trichoscopy donor density scan. This measures actual follicular units per cm² in the donor zone — not a population average estimate. Combined with recipient zone surface area measurement and target density discussion, this produces a precise graft plan.
