The Norwood scale (formally the Hamilton-Norwood scale) is the most widely used classification system for male pattern hair loss. Understanding which Norwood stage you are at helps determine the most appropriate treatment approach and sets realistic expectations for what hair transplantation can achieve.
Norwood Type 1
No significant recession. The hairline sits in the juvenile position. No treatment typically needed, though early medical prevention may be considered with a strong family history.
Norwood Type 2
Slight temporal recession. Hair loss is minimal. Medical treatment (finasteride, minoxidil) is appropriate. Hair transplantation may be premature.
Norwood Type 3
More pronounced M-shaped temporal recession. Hair transplantation to the temples and front hairline is appropriate. Medical treatment to stabilise surrounding hair is strongly recommended. Type 3 Vertex adds early crown thinning.
Norwood Type 4
Significant temporal recession combined with crown thinning. A band of hair still connects the sides. Transplant sessions of 2,500–4,000 grafts are typical.
Norwood Type 5
The connecting band becomes significantly narrower. Large sessions of 3,500–5,000 grafts are typically required. Strategic planning is essential.
Norwood Type 6
The connecting band has largely disappeared. Extensive baldness covers top and crown. Large or staged procedures required.
Norwood Type 7
The most advanced stage. Only a horseshoe-shaped band remains. Requires careful donor density assessment and realistic coverage expectations.
Norwood Scale and Hair Transplant Planning
Norwood stage informs graft requirements, priority zones, donor supply assessment, and long-term planning. Lower Norwood patients (2–4) must plan for future progression — a transplant designed for Norwood 3 should anticipate likely progression to Norwood 4–5.
Ludwig Scale for Women
Women's hair loss uses the Ludwig scale (Grade I–III), as the diffuse thinning pattern differs significantly from male pattern loss. Female hair loss rarely reaches complete baldness.
