Tabla de referencia de injertos Norwood

Rangos típicos de injertos por etapa. Tu cirujano puede recomendar más o menos según objetivos y donante.

Etapa Norwood	Injertos típicos	Patrón
Norwood 1	Normalmente no necesario	Pérdida mínima o ninguna. El trasplante normalmente no es necesario.
Norwood 2	800–1,500	Ligera recesión en las sienes. A menudo 800–1.500 injertos.
Norwood 3	1,500–2,500	Recesión más profunda con adelgazamiento inicial. Típicamente 1.500–2.500 injertos.
Norwood 3 Vertex	2,000–3,000	Sienes más vertex adelgazándose. A menudo 2.000–3.000 injertos.
Norwood 4	2,500–3,500	Pérdida frontal significativa con corona afectada. Usualmente 2.500–3.500 injertos.
Norwood 5	3,500–4,500	Gran área calva conectando frente y corona. A menudo 3.500–4.500 injertos.
Norwood 6	4,500–5,500	Casi toda la parte superior calva con banda lateral. Típicamente 4.500–5.500 injertos.
Norwood 7	5,500–7,000	Solo queda un fino herradura. Casos avanzados: 5.500–7.000+ injertos.

How the Norwood scale maps to graft count

The Norwood scale classifies male pattern hair loss from stage 1 (minimal recession) to stage 7 (extensive loss). Early stages (2–3) often need 800–2,500 grafts for hairline work; mid stages (4–5) commonly require 2,500–4,500 grafts when adding mid-scalp or crown coverage; advanced stages (6–7) may need 4,500–7,000+ grafts for broader restoration.

Vertex thinning (Norwood 3V) typically adds 500–1,000 grafts on top of a hairline plan because the crown is a separate zone with its own angulation and density targets.

What affects your final graft number

Donor density, hair calibre, and whether you want a conservative hairline or maximum density all change the graft total. Two patients at the same Norwood stage can need different counts if one prioritises frontal framing only and the other wants full top coverage.

Preguntas frecuentes

How many grafts do I need for Norwood 3?: Norwood 3 typically requires 1,500–2,500 grafts for hairline and temple restoration. If you also have crown thinning (Norwood 3V), plan for roughly 2,000–3,000 grafts in total.
How many grafts for Norwood 4 or 5?: Norwood 4 often needs 2,500–3,500 grafts when treating hairline plus mid-scalp. Norwood 5 commonly ranges from 3,500–4,500 grafts because both the front and crown zones need coverage.
Is one graft the same as one hair?: No. A graft is a follicular unit that usually contains 1–3 hairs. Clinics quote in grafts; total hair count is higher. Density results depend on graft quality, placement angle, and how many hairs each graft contains.
Can I get an accurate count without a consultation?: Online tools provide a planning range. A surgeon or our free head scan consultation refines the number using donor availability, hair characteristics, and your aesthetic goals.
How do grafts relate to cost in Turkey?: Turkey clinics often price all-inclusive packages by graft band (e.g. up to 3,000 or 4,000 grafts). Estimate grafts here, then open the cost calculator to see typical Istanbul package ranges for your case.
