Realistic coverage from a hair transplant depends on how many grafts you receive and the size of the area being treated. A 2,000-graft procedure covering 40 cm2 produces approximately 50 follicular units per cm2, which creates visible coverage but falls short of native untouched density (65-100+ FU/cm2).
Coverage Density by Graft Count
The following table shows the relationship between graft count, coverage area, and the resulting density. These figures assume standard FUE placement with a 90-95% graft survival rate.
| Graft Count | Small Area (20 cm2) | Medium Area (40 cm2) | Large Area (60 cm2) | Very Large Area (80 cm2) |
|---|---|---|---|---|
| 1,000 | 50 FU/cm2 | 25 FU/cm2 | 17 FU/cm2 | 13 FU/cm2 |
| 1,500 | 75 FU/cm2 | 38 FU/cm2 | 25 FU/cm2 | 19 FU/cm2 |
| 2,000 | 100 FU/cm2 | 50 FU/cm2 | 33 FU/cm2 | 25 FU/cm2 |
| 2,500 | N/A (area too small) | 63 FU/cm2 | 42 FU/cm2 | 31 FU/cm2 |
| 3,000 | N/A | 75 FU/cm2 | 50 FU/cm2 | 38 FU/cm2 |
| 3,500 | N/A | 88 FU/cm2 | 58 FU/cm2 | 44 FU/cm2 |
| 4,000 | N/A | N/A | 67 FU/cm2 | 50 FU/cm2 |
| 5,000 | N/A | N/A | 83 FU/cm2 | 63 FU/cm2 |
Key threshold: Most patients find 35-50 FU/cm2 cosmetically satisfying. Below 30 FU/cm2, scalp remains visible in most lighting conditions.
What These Numbers Mean Visually
Density numbers translate to real-world appearance as follows:
| Density (FU/cm2) | Visual Appearance | Who Sees This |
|---|---|---|
| 15-25 | Scalp clearly visible, thin look | Below minimum useful density |
| 25-35 | Scalp visible in bright light, improved from baseline | Light coverage, good for starting point |
| 35-50 | Good coverage, scalp mostly concealed | Most transplant patients |
| 50-65 | Strong density, difficult to tell transplant occurred | High graft counts on smaller areas |
| 65-100+ | Native untouched density | Non-balding scalp |
Each follicular unit contains an average of 2.2 hairs, so 40 FU/cm2 actually delivers approximately 88 individual hairs per cm2.
Coverage by Norwood Stage
Your Norwood stage determines the area needing coverage. Here is how graft count and stage interact:
Norwood 2 (800-1,500 Grafts)
- Area needing coverage: 10-20 cm2 (temple recession only)
- Achievable density: 50-75 FU/cm2
- Outcome: Excellent coverage, very natural result with strong frontal density
Norwood 3 (1,500-2,200 Grafts)
- Area needing coverage: 20-35 cm2 (deeper temple recession)
- Achievable density: 45-65 FU/cm2
- Outcome: Strong hairline restoration, good midscalp coverage
Norwood 4 (2,500-3,500 Grafts)
- Area needing coverage: 40-60 cm2 (hairline + crown)
- Achievable density: 40-55 FU/cm2
- Outcome: Good coverage across both zones, may need graft prioritization between front and crown
Norwood 5 (3,000-4,500 Grafts)
- Area needing coverage: 60-80 cm2
- Achievable density: 35-50 FU/cm2
- Outcome: Satisfying coverage with careful distribution. Finasteride/minoxidil recommended to support remaining native hair
Norwood 6-7 (4,000-7,500 Grafts)
- Area needing coverage: 80-120+ cm2
- Achievable density: 30-45 FU/cm2
- Outcome: Coverage is achievable but density is limited by donor supply. Two sessions typically needed. Medications are essential

Factors That Affect Coverage Quality
Graft count and area size are not the only variables. Several patient-specific factors significantly influence how dense the result appears:
Hair Characteristics
| Factor | Better Coverage | Worse Coverage |
|---|---|---|
| Hair caliber | Thick, coarse strands | Fine, thin strands |
| Hair-to-skin contrast | Low (blonde hair, fair skin) | High (dark hair, light skin) |
| Curl pattern | Curly or wavy | Straight |
| Hairs per graft | 2.5-3.0 avg | 1.5-2.0 avg |
Ethnic Density Baselines
Natural follicular density varies by ethnicity, which affects both the starting point and what the transplanted result looks like in context:
| Ethnicity | Native Density (FU/cm2) |
|---|---|
| Caucasian | 170-230 (avg 200) |
| Middle Eastern | 150-210 (avg 180) |
| Asian | 140-200 (avg 170) |
| Hispanic | 145-195 (avg 170) |
| African | 120-180 (avg 150) |
African hair typically has fewer follicular units per cm2 but greater curl, which provides more coverage per strand. Asian hair has lower unit density but thicker individual strands.
How to Use This Data
Before Your Consultation
- Identify your Norwood stage with the free AI tool at myhairline.ai/analyze
- Find your stage in the tables above to see your expected area and graft range
- Calculate expected density by dividing your graft count by the area
During Your Consultation
- Ask your surgeon to confirm the graft count and specify the distribution by zone
- Ask what density (FU/cm2) they are targeting for each zone
- Request before/after photos of patients at the same Norwood stage
After Your Procedure
- Track progress with monthly comparison photos
- Review your results against the density expectations by graft count benchmarks
- Follow the complete hair transplant growth timeline for month-by-month expectations
Frequently Asked Questions
When will I see results after hair transplant?
Expect initial fine hairs at months 3-4, visible density improvement at months 6-8, and full matured results at 12-18 months. FUE graft survival rates sit at 90-95%, meaning the vast majority of placed grafts will produce permanent hair.
Is shock loss after hair transplant normal?
Yes. Shock loss affects most patients between weeks 2 and 6 post-surgery. The transplanted hairs shed as part of the normal hair cycle, but the follicles survive beneath the skin. Regrowth begins at month 3-4 and continues to thicken through month 18.
How do I know if my hair transplant is working?
Track progress with consistent monthly photos taken under the same lighting conditions. Fine hairs should appear by month 3-4. By month 8-10, density should be visibly improved compared to pre-op photos. If no growth appears by month 6, consult your surgeon for an evaluation.
