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.
Tabella di riferimento innesti Norwood
Intervalli tipici per stadio. Il chirurgo può consigliare più o meno innesti in base a obiettivi e donatore.
| Stadio Norwood | Innesti tipici | Pattern |
|---|---|---|
| Norwood 1 | Di solito non necessario | Perdita minima o assente. Il trapianto di solito non è necessario. |
| Norwood 2 | 800–1,500 | Leggero arretramento delle tempie. Spesso 800–1.500 innesti. |
| Norwood 3 | 1,500–2,500 | Arretramento più profondo con diradamento iniziale. Tipicamente 1.500–2.500 innesti. |
| Norwood 3 Vertex | 2,000–3,000 | Tempie più corona che inizia a diradarsi. Spesso 2.000–3.000 innesti. |
| Norwood 4 | 2,500–3,500 | Perdita frontale significativa con coinvolgimento corona. Di solito 2.500–3.500 innesti. |
| Norwood 5 | 3,500–4,500 | Ampia area calva che collega fronte e corona. Spesso 3.500–4.500 innesti. |
| Norwood 6 | 4,500–5,500 | Quasi tutta la sommità calva con fascia laterale. Tipicamente 4.500–5.500 innesti. |
| Norwood 7 | 5,500–7,000 | Resta solo un sottile ferro di cavallo. Casi avanzati 5.500–7.000+ innesti. |
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.
