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.
Norwood scale graft reference chart
Typical graft ranges for full-zone restoration at each stage. Your surgeon may recommend fewer or more grafts based on goals and donor quality.
| Norwood stage | Typical grafts | Pattern |
|---|---|---|
| Norwood 1 | Usually not needed | Minimal or no visible hair loss. A transplant is usually not needed. |
| Norwood 2 | 800–1,500 | Slight recession at the temples. Early-stage restoration may need 800–1,500 grafts. |
| Norwood 3 | 1,500–2,500 | Deeper temple recession with early thinning on top. Typically 1,500–2,500 grafts. |
| Norwood 3 Vertex | 2,000–3,000 | Temple recession plus vertex (crown) thinning starting. Often 2,000–3,000 grafts. |
| Norwood 4 | 2,500–3,500 | Significant front hair loss with crown involvement. Usually 2,500–3,500 grafts. |
| Norwood 5 | 3,500–4,500 | Large bald area connecting front and crown. Often 3,500–4,500 grafts. |
| Norwood 6 | 4,500–5,500 | Most of the top is bald with a band of hair on the sides. Typically 4,500–5,500 grafts. |
| Norwood 7 | 5,500–7,000 | Only a narrow horseshoe of hair remains. Advanced cases may need 5,500–7,000+ grafts. |
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.
