Norwood 3 requires 1,500 to 2,200 grafts for a typical restoration. The zone split is approximately 50% hairline, 30% temples, and 20% mid-scalp. This is the minimum stage most surgeons consider for transplant, and getting the graft count right here protects your donor supply for any future needs.

Why Graft Count Matters at Norwood 3
At Norwood 3, the area of loss is substantial enough to require meaningful graft investment, but small enough that a single well-planned session can produce a significant cosmetic improvement. The challenge is calculating an accurate graft requirement that accounts not just for today's pattern, but for the likelihood of future progression.
Surgeons who underestimate graft requirements at Norwood 3 produce thin, see-through results. Those who overestimate risk depleting a disproportionate share of the donor supply in a single early session. The 1,500 to 2,200 graft range represents the clinical consensus for a Norwood 3 pattern that produces adequate density without excessive donor depletion.
Zone-by-Zone Breakdown
The standard zone allocation for Norwood 3 divides the recipient area into three functional regions. Each zone has different density targets, graft type requirements, and design priorities.
| Zone | Proportion of Grafts | Typical Count | Density Target |
|---|---|---|---|
| Hairline (frontal) | 50% | 750-1,100 | 40-50 FU/cm2 |
| Temples | 30% | 450-660 | 25-35 FU/cm2 |
| Mid-scalp transition | 20% | 300-440 | 30-40 FU/cm2 |
Hairline Zone (50%)
The hairline zone is the highest-priority area at Norwood 3. It spans approximately 3 to 5 cm from the front edge of the designed hairline back toward the existing hair. This zone creates the primary visual impact of the procedure: the visible hairline that frames the face.
The leading edge of the hairline requires single-hair grafts placed at acute angles (10 to 15 degrees) to create a soft, natural transition. Behind this leading edge, two-hair grafts provide the density backbone. The highest density in the entire session is concentrated in the central 2 cm of the hairline, which produces the forelock anchor point that matters most for visual coverage from the front.
Temple Zone (30%)
Temple restoration at Norwood 3 addresses the deep bilateral recession that defines this stage. The temple zones are anatomically challenging because the hair direction changes significantly as you move along the recession line, transitioning from downward-facing in the lower temple to increasingly lateral as you move up toward the temporal peak.
Temple grafts are placed at sharper angles than hairline grafts, often 5 to 10 degrees from the scalp surface, to create the flat, forward-pointing growth direction characteristic of natural temporal hair. Density is intentionally lower at the temple leading edge (15 to 25 FU/cm2) and slightly higher in the central temple body (25 to 35 FU/cm2).
Mid-Scalp Transition Zone (20%)
The mid-scalp transition zone is the area between the designed hairline and the existing native hair. At Norwood 3, this zone is typically still hair-bearing but may show some miniaturization. Adding grafts here creates a smooth density gradient from the transplanted hairline back into the existing hair, preventing a visible demarcation line.
This zone often receives fewer grafts in practice, particularly if the existing native hair provides adequate transition. Surgeons may deprioritize this zone to conserve grafts for the primary hairline and temple zones.
How Hair Characteristics Affect Graft Requirements
Two patients presenting with identical Norwood 3 patterns can have very different graft requirements based on their natural hair characteristics.
Hair caliber (thickness): Hair caliber is measured in microns. Fine hair (less than 60 microns in diameter) requires more grafts per square centimeter to achieve the same visual coverage as coarse hair (above 80 microns). A patient with fine hair may need a count at the upper end of the 1,500 to 2,200 range; a patient with coarse hair may achieve good results at the lower end.
Natural color contrast: High contrast between hair color and scalp skin, such as dark hair on fair skin, makes individual grafts more visible and lower-density areas more apparent. High-contrast patients typically need higher recipient densities, pushing graft requirements toward the upper bound.
Curl pattern: Curly and wavy hair provides more visual coverage per graft because each strand occupies more lateral space and helps fill gaps. Patients with curly hair often achieve natural-looking density at lower graft counts than patients with straight hair.
Follicular unit size: Some men naturally have higher proportions of two- and three-hair follicular units in their donor zone. These multi-hair units provide greater density per graft than predominantly single-hair donors.
FUE vs. FUT Graft Yield at Norwood 3
The surgical technique affects how efficiently grafts can be harvested and delivered.
| Factor | FUE | FUT |
|---|---|---|
| Max grafts per session | 2,000-3,000 | 2,500-4,000 |
| Graft survival rate | 85-95% | 90-98% |
| Scarring | Tiny punch marks | Linear scar |
| Recovery time | 5-7 days | 10-14 days |
| Best for Norwood 3 | Yes, standard choice | Optional if high yield needed |
For most Norwood 3 patients, FUE provides more than enough graft yield in a single session while minimizing scarring and recovery time. FUT becomes a preference when the patient wants to maximize yield, has borderline donor density, or plans to wear their hair very short (where the linear FUT scar may be less of a concern than punch mark density from FUE).
Norwood 3V: Additional Graft Requirements for Crown Coverage
If the Norwood 3 Vertex variant is present, additional grafts are needed for the crown. Crown coverage adds approximately 400 to 800 grafts for early, limited thinning. Most surgeons prefer to defer crown coverage at Norwood 3V, reserving it for a second session once the hairline restoration has healed and the extent of crown progression is better understood.
Committing large crown graft counts at Norwood 3V is generally inadvisable because the crown continues to progress and early coverage can give the illusion of completion when more loss may be coming. The exception is the older patient (typically 45 or above) whose loss pattern has been stable for many years and whose lifetime progression is more predictable.
Graft Survival and What Affects It
Not all transplanted grafts survive. Graft survival rates at Norwood 3 range from 85 to 98% depending on the clinic's technique, graft handling protocols, and the patient's biology. Poor graft handling, dehydration of grafts outside the body, and suboptimal implantation angles all reduce survival.
Key factors that support optimal graft survival:
- Minimal time out of body for harvested grafts (ideally less than 4 hours)
- Storage in a chilled saline or HypoThermosol solution
- Experienced graft sorters who minimize follicle trauma during separation
- Proper depth and angle for recipient site creation
- Adequate scalp blood supply in the recipient zone
Before committing to a clinic, ask about their documented graft survival protocol and whether they use HypoThermosol or ATP solutions for graft preservation.
Planning the Second Session
At Norwood 3, it is worth asking your surgeon about their long-term planning approach even if you are only committing to a first session. A thoughtful surgeon will calculate how many grafts remain in your donor zone after the first session and model out what the second session could address if your hair loss advances.

Frequently Asked Questions
What does Norwood 3 look like?
Norwood 3 shows a pronounced M or U-shaped hairline with deep bilateral temple recession extending well past the outer corner of the eye. The central forelock is generally intact and the crown is not yet significantly affected in standard Norwood 3, though the Norwood 3 Vertex variant adds early crown thinning.
How many grafts are needed at Norwood 3?
Norwood 3 typically requires 1,500 to 2,200 grafts. The zone split is approximately 50% to the hairline, 30% to the temples, and 20% to the mid-scalp transition zone. This range reflects average cases; individual requirements depend on recession depth, desired density, and hair characteristics.
What are the best treatments at Norwood 3?
FUE hair transplant combined with finasteride is the most effective approach at Norwood 3 for patients seeking to restore their hairline. Finasteride protects native hair behind the transplant zone and reduces the need for additional sessions over time. Minoxidil is often added as a second medical adjunct.
