Norwood 7 represents the most advanced stage of male pattern baldness, and a donor assessment at this stage must be brutally honest about what surgery can and cannot achieve. The recipient area deficit requires 6,000 to 8,000 grafts for comprehensive coverage, a number that exceeds the safe harvest capacity of nearly every donor area. Patients who understand their real numbers before committing to surgery make better decisions and avoid the most common outcome of disappointment: spending significant money on a result that falls short of expectations set by misleading consultations.

The Donor Assessment Framework at Norwood 7
The assessment measures the same four variables as earlier stages. At Norwood 7, the numbers must be interpreted against a much larger deficit.
Donor Density
Density is measured with a dermoscope at multiple points across the safe donor zone. Baseline density varies by ethnicity.
| Ethnicity | Typical Hair Density (hairs/cm2) | Approximate FU/cm2 |
|---|---|---|
| Caucasian | 170 to 230 | 75 to 100 |
| African | 120 to 180 | 55 to 80 |
| Asian | 140 to 200 | 60 to 90 |
At Norwood 7, here is what the numbers typically look like for an average patient:
- Total donor units: 6,000 to 8,000
- Safe harvest at 45%: 2,700 to 3,600 grafts
- Norwood 7 full coverage demand: 6,000 to 8,000 grafts
- Supply-to-demand ratio: approximately 35 to 55%
This means even the best donor areas can supply only about half the grafts needed for comprehensive Norwood 7 restoration. The assessment must determine exactly where on this spectrum you fall.
Safe Zone Mapping
The safe zone at Norwood 7 may be narrower than at earlier stages. As the pattern has fully matured, the surgeon can more accurately identify the permanent zone because the boundary between resistant and susceptible follicles is now clearly established.
| Safe Zone Size | Area (cm2) | Harvestable Grafts (at 80 FU/cm2) |
|---|---|---|
| Narrow | 60 to 75 | 2,160 to 2,700 |
| Average | 80 to 100 | 2,880 to 3,600 |
| Wide | 100 to 120 | 3,600 to 4,320 |
Patients with a narrow safe zone face the harshest constraints. Even a frontal-only restoration may consume a large percentage of their supply.
Scalp Laxity
At Norwood 7, maximizing total graft yield is critical, which makes the FUT versus FUE decision particularly important. Laxity directly affects FUT feasibility.
Good laxity allows a wide donor strip yielding 2,500 to 3,500 grafts in a single FUT session. A follow-up FUE session can harvest additional units from around the scar. This combined approach maximizes total yield from the donor area and is often the best strategy at Norwood 7 for patients who accept the linear scar trade-off. See our FUE vs FUT comparison for a detailed analysis.
Tight-scalp patients are limited to FUE only, which may require two or three sessions spaced 10 to 14 months apart to safely extract 3,000 to 3,500 total grafts.
Hair Characteristics
At Norwood 7, favorable hair characteristics are the difference between a "good enough" result and an obviously thin transplant.
| Characteristic | Favorable for Norwood 7 | Unfavorable for Norwood 7 |
|---|---|---|
| Caliber | Coarse (70+ microns) | Fine (under 50 microns) |
| Hairs per unit | 3 to 4 average | Mostly singles |
| Curl pattern | Curly or wavy | Straight |
| Color contrast | Low | High (dark hair, pale scalp) |
A patient with coarse, curly, multi-hair follicular units and low color contrast may achieve a natural-appearing frontal result with 2,500 to 3,000 grafts. A patient with fine, straight, high-contrast hair at the same stage needs significantly more grafts for comparable coverage, grafts that likely exceed safe supply.
What Norwood 7 Surgery Can Realistically Achieve
Setting realistic expectations is the surgeon's most important job at this stage. Here is what different graft budgets deliver at Norwood 7.
| Available Grafts | Coverage Achievable | Recommended Strategy |
|---|---|---|
| Under 2,000 | Frontal hairline frame only | Narrow frontal band + SMP for crown |
| 2,000 to 3,000 | Frontal zone with low-medium density | Hairline and anterior midscalp + SMP or fibers |
| 3,000 to 4,000 | Frontal zone with moderate density | Hairline through midscalp, feathered crown edge |
| 4,000+ (rare) | Extended frontal + partial crown | Prioritize front, conservative crown density |
Full, thick coverage from hairline to crown vertex is not achievable at Norwood 7 with scalp donor hair alone. Patients who insist on this outcome will either be turned away by ethical surgeons or over-harvested by unethical ones.
Supplementary Donor Sources
Beard Hair
Beard hair is the most viable supplementary source. It is coarse, grows in single units, and has a reasonable growth phase. Experienced BHT surgeons can harvest 1,000 to 2,000 grafts from the beard and submandibular area.
Beard grafts are best placed behind the frontal scalp-hair zone to add density in the midscalp and crown, where their slightly different texture is less noticeable.
Chest and Body Hair
Chest hair is finer and has a shorter growth cycle than beard or scalp hair. It provides minimal coverage per graft and is useful only as a last-resort supplement. The same applies to leg and arm hair.
Combined Approach
The most comprehensive Norwood 7 plan for well-supplied patients looks like this:
| Source | Grafts | Placement |
|---|---|---|
| Scalp FUT | 2,500 to 3,500 | Frontal hairline and midscalp |
| Scalp FUE (session 2) | 1,000 to 1,500 | Density fill in frontal zone |
| Beard BHT (session 3) | 1,000 to 1,500 | Midscalp and crown density |
| Total | 4,500 to 6,500 | Spread across 2 to 3 years |
This is an aggressive strategy that requires an exceptional donor area and an experienced multi-technique surgeon. It is not available to most patients.
Red Flags at Norwood 7
Be especially cautious of clinics that:
- Promise full Norwood 7 coverage in one or two sessions
- Quote 6,000 or more FUE grafts from scalp alone
- Do not discuss the 45% safe extraction limit
- Show before-and-after photos that seem too good for the stated Norwood stage
- Do not mention SMP or supplementary approaches as part of the plan
- Downplay the supply-demand gap
The most trustworthy consultation at Norwood 7 is one where the surgeon tells you what cannot be done as clearly as what can. Refer to the Norwood scale guide for an overview of all stages and their typical progression.
Frequently Asked Questions
Can you get a hair transplant at Norwood 7?
Surgery is possible at Norwood 7 but with substantial limitations. Full coverage requires 6,000 to 8,000 grafts or more, while most donor areas can safely supply 2,000 to 4,000 grafts (at the 45% extraction limit). The realistic outcome is partial restoration focused on the frontal hairline, often combined with SMP or concealer products for crown density.
How much donor hair is left at Norwood 7?
The donor zone itself is not affected by pattern baldness. The safe band at the back and sides retains its original density. However, the safe zone may be narrower at Norwood 7 because the upper boundary of DHT-resistant hair can shrink. Average total supply remains 5,000 to 8,000 units, with 45% safely harvestable.
Is body hair transplant effective at Norwood 7?
Body hair (beard, chest) can supplement scalp donor supply but has limitations: shorter growth cycles, thinner caliber, and different texture. Beard hair is the best supplementary source. BHT can add 1,000 to 2,000 grafts for density fill but should not be relied on as the primary source. Results vary by surgeon experience.
