Crown coverage after a hair transplant depends on three factors: graft count, the size of the thinning area, and realistic density targets. Most crown procedures use 1,000-3,000 grafts and achieve cosmetically satisfying coverage, though rarely matching the density of untouched native hair.
Why the Crown Is Different from the Hairline
The crown (vertex) presents unique challenges compared to hairline restoration:
- Larger surface area. A Norwood 5 or 6 crown bald spot can cover 50-80 cm2, compared to 15-30 cm2 for a typical hairline restoration
- Spiral growth pattern. Crown hair grows in a whorl pattern, requiring precise angle and direction during placement
- Lower blood supply. The vertex receives less blood flow than the frontal scalp, which can slightly reduce graft survival rates
- Progressive loss. The crown continues to thin with age, meaning transplanted hair may eventually stand out against thinning surrounding hair
These factors do not mean crown transplants fail. They mean expectations need calibrating before surgery.
Graft Requirements by Crown Coverage Level
The table below shows the relationship between graft count, coverage area, and resulting density for crown procedures.
| Grafts to Crown | Coverage Area | Resulting Density (FU/cm2) | Visual Result |
|---|---|---|---|
| 500-800 | 15-20 cm2 | 30-40 | Light camouflage, scalp still partially visible |
| 800-1,500 | 20-35 cm2 | 30-45 | Moderate coverage, noticeable improvement |
| 1,500-2,500 | 35-60 cm2 | 35-50 | Good coverage, most patients satisfied |
| 2,500-3,500 | 60-80 cm2 | 35-45 | Wider area covered, solid cosmetic result |
For reference, native untouched scalp density ranges from 65-100 FU/cm2 in most ethnicities. Transplant density of 35-50 FU/cm2 creates the appearance of full coverage when combined with proper hair styling and maintenance medications.
Crown Coverage by Norwood Stage
Your Norwood stage determines how much crown area needs coverage and how many grafts go to the crown vs. the hairline.
Norwood 3V (Crown + Temple Recession)
- Crown area: 15-25 cm2 (early vertex thinning)
- Grafts to crown: 500-1,000
- Total grafts needed: 2,000-2,800
- Coverage expectation: Good density achievable since the area is small
- Strategy: Address crown early before the bald spot expands
Norwood 4 (Enlarged Crown Spot)
- Crown area: 25-40 cm2
- Grafts to crown: 800-1,500
- Total grafts needed: 2,500-3,500
- Coverage expectation: Solid cosmetic improvement with proper graft distribution
- Strategy: Balance grafts between hairline and crown based on patient priorities
Norwood 5 (Bridge Narrowing)
- Crown area: 40-60 cm2
- Grafts to crown: 1,200-2,000
- Total grafts needed: 3,000-4,500
- Coverage expectation: Good coverage, though density will be below native levels
- Strategy: Some surgeons recommend prioritizing the hairline and using medications to maintain crown coverage
Norwood 6-7 (Full Crown Loss)
- Crown area: 60-100+ cm2
- Grafts to crown: 2,000-3,500
- Total grafts needed: 4,000-7,500
- Coverage expectation: Coverage is achievable but density per cm2 is limited by donor supply
- Strategy: Often requires two sessions; finasteride or minoxidil strongly recommended to support transplanted and remaining native hair

How to Maximize Crown Coverage Results
Step 1: Know Your Stage Before Consulting
Get your Norwood stage identified with the Norwood scale guide or the free AI tool at myhairline.ai. This prevents relying solely on a clinic's assessment, which may not always align with your own research.
Step 2: Discuss Graft Distribution
During your consultation, ask your surgeon how they plan to split grafts between the hairline, midscalp, and crown. Common distributions:
| Priority | Hairline | Midscalp | Crown |
|---|---|---|---|
| Hairline-first | 50-60% | 20-25% | 15-25% |
| Balanced | 35-40% | 25-30% | 30-35% |
| Crown-focused | 20-25% | 20-25% | 50-60% |
Most surgeons recommend a hairline-first approach for younger patients, since a defined frontal frame creates the strongest visual impact.
Step 3: Commit to Maintenance Medications
Crown coverage relies heavily on preserving existing native hair around the transplanted grafts. Without maintenance:
- Finasteride (1mg daily): Halts further loss in 80-90% of users, with 65% experiencing some regrowth. Side effects occur in 2-4% of users and are reversible
- Minoxidil (5% topical, twice daily): Produces moderate regrowth in 40-60% of users. Particularly effective for crown density
Stopping medications after a crown transplant often leads to a "halo effect" where transplanted hair survives but surrounding native hair continues to thin, creating an unnatural appearance.
Step 4: Set a Realistic Timeline
Crown transplants take longer to show results than hairline procedures:
| Month | What to Expect |
|---|---|
| 0-1 | Healing, scabbing, redness |
| 1-3 | Shock loss (transplanted hairs shed, this is normal) |
| 3-5 | Early fine hairs begin emerging |
| 6-8 | Noticeable new growth, still thin |
| 8-12 | Significant density increase |
| 12-18 | Final result, full maturation |

Step 5: Plan for a Possible Second Session
Patients at Norwood 5 or higher often benefit from a second session 12-18 months after the first to add density to the crown or fill any thin patches. Donor supply is the limiting factor, with a safe extraction limit of approximately 45% of available donor follicles across all sessions combined.
Common Mistakes with Crown Transplants
- Ignoring the hairline. A full crown with no hairline creates an unnatural look. Most surgeons address both areas
- Skipping medications. Crown results degrade over time without finasteride or minoxidil to protect surrounding hair
- Expecting native density. Transplant density of 35-50 FU/cm2 creates good coverage but does not match untouched scalp density of 65-100+ FU/cm2
- Judging results too early. Crown growth is slower. Wait the full 18 months before evaluating your outcome
Frequently Asked Questions
When will I see my final hair transplant result?
Final results from a crown transplant typically appear at 12-18 months post-surgery. The crown area tends to be slower than the hairline because of reduced blood supply to the vertex. Most patients see noticeable density at 8-10 months, with continued thickening through month 18.
What does a successful hair transplant look like?
A successful crown transplant achieves visible density that reduces or eliminates the appearance of scalp showing through. Full native density (80-100 follicular units per cm2) is rarely achievable in a single session, but 35-50 FU/cm2 creates a cosmetically satisfying result for most patients.
How do I know if my hair transplant worked?
Signs of a working transplant include small hairs emerging from the recipient area starting at months 3-4, gradual thickening from months 6-10, and progressive density increase through month 18. If you see no growth by month 6, consult your surgeon for evaluation.
