Norwood Scale Graft Chart
Reference graft ranges for every Norwood stage — then use the interactive calculator.
The Norwood-Hamilton scale is the standard classification for male pattern hair loss. Surgeons use your stage plus donor quality to plan graft allocation across hairline, mid-scalp, and crown. The table below shows typical graft bands; individual cases vary.
Tableau de référence greffons Norwood
Fourchettes typiques par stade. Votre chirurgien peut ajuster selon vos objectifs et la zone donneuse.
| Stade Norwood | Greffons typiques | Motif |
|---|---|---|
| Norwood 1 | Généralement inutile | Perte minimale ou absente. Greffe généralement non nécessaire. |
| Norwood 2 | 800–1,500 | Légère récession des tempes. Souvent 800–1 500 greffons. |
| Norwood 3 | 1,500–2,500 | Récession plus profonde avec amincissement initial. Typiquement 1 500–2 500 greffons. |
| Norwood 3 Vertex | 2,000–3,000 | Tempes plus vertex qui s'amincit. Souvent 2 000–3 000 greffons. |
| Norwood 4 | 2,500–3,500 | Perte frontale significative avec couronne touchée. Généralement 2 500–3 500 greffons. |
| Norwood 5 | 3,500–4,500 | Grande zone chauve reliant le devant et la couronne. Souvent 3 500–4 500 greffons. |
| Norwood 6 | 4,500–5,500 | Presque tout le dessus est chauve avec une bande latérale. Typiquement 4 500–5 500 greffons. |
| Norwood 7 | 5,500–7,000 | Il ne reste qu'un fin fer à cheval. Cas avancés : 5 500–7 000+ greffons. |
Reading the Norwood stages
Stages 1–2: minimal recession — transplants are uncommon. Stage 3: noticeable hairline recession. Stage 3V: added crown thinning. Stages 4–5: front and top involvement. Stages 6–7: extensive loss requiring large-scale planning, sometimes with beard or body hair if donor is limited.

Frequently asked questions
- What is the Norwood scale?
- It is a 7-stage system describing progressive male pattern baldness, from minimal recession to severe loss. It helps patients and surgeons communicate hair loss severity.
- How many grafts for Norwood 3V?
- Norwood 3V (vertex) typically needs 2,000–3,000 grafts when treating both hairline recession and crown thinning together.
- Can one session cover Norwood 6 or 7?
- Often yes for a first session targeting the most visible zones, but advanced stages may need 5,000–7,000+ grafts or a two-session strategy depending on donor capacity.
- Is the chart a medical diagnosis?
- No. It is an educational reference. A qualified surgeon confirms stage, donor availability, and realistic density goals.
