Crown and hairline transplants follow different growth timelines, and understanding the gap between them prevents unnecessary worry during recovery. The hairline typically shows visible results 2 to 3 months before the crown reaches equivalent density, which is a biological reality rather than a sign of failure.

Why the Crown and Hairline Grow at Different Rates
Blood supply is the primary factor driving the difference. The frontal scalp receives blood from the supratrochlear and supraorbital arteries, which provide strong, consistent flow to the hairline region. The crown depends on branches of the occipital and posterior auricular arteries, which reach the vertex through a longer pathway with less direct perfusion.
Better blood supply means faster nutrient delivery to newly transplanted follicles. This translates to earlier anagen (growth phase) entry for hairline grafts compared to crown grafts. Tissue thickness also plays a role. The scalp at the vertex is thinner than at the frontal zone, which affects how quickly grafts anchor and begin producing visible hair.
Month-by-Month Comparison: Hairline vs Crown
The table below summarizes expected growth milestones for each zone after an FUE procedure with 90 to 95% graft survival.
| Timeframe | Hairline Zone | Crown Zone |
|---|---|---|
| Week 1 to 2 | Scabbing, redness, initial healing | Scabbing, redness, initial healing |
| Month 1 to 2 | Shock loss of transplanted hairs | Shock loss of transplanted hairs |
| Month 3 | First new hairs appear (fine, thin) | Minimal visible growth |
| Month 4 to 5 | Noticeable coverage starting | Early fine hairs emerging |
| Month 6 | 50 to 60% of final density | 30 to 40% of final density |
| Month 9 | 70 to 80% of final density | 55 to 65% of final density |
| Month 12 | 85 to 95% of final density | 70 to 85% of final density |
| Month 15 to 18 | Final result | Final result (may take full 18 months) |
These ranges apply to the majority of patients, but individual variation is significant. Factors including age, overall health, smoking status, and adherence to post-operative care all affect the timeline.
The Hairline Timeline in Detail
Hairline grafts typically enter the growth phase earliest because of their superior blood supply and the relatively thick tissue in the frontal zone. Here is what to expect:
Months 1 to 3: The Waiting Period
After initial healing and shock loss, the transplant zone looks essentially unchanged or even thinner than before surgery. This is normal. The follicles are alive but dormant beneath the surface. Around week 10 to 12, small bumps and fine stubble begin appearing. These early hairs are thin and translucent.
Months 4 to 8: Visible Progress
New hairs thicken and darken progressively. By month 6, most hairline patients can see a clear difference from their pre-surgery state. Hair texture may initially differ from native hair, appearing wiry or curly before straightening over the following months.
Months 9 to 12: Near-Final Result
The hairline approaches its final density during this window. Individual hairs continue to thicken, and the overall appearance becomes more natural as hair length allows for styling. Most surgeons consider the hairline result largely complete by month 12.
The Crown Timeline in Detail
Crown transplants follow a similar biological sequence but on a delayed schedule. The vertex area is simply slower to show results, and this is well documented across clinical studies.
Months 1 to 4: Extended Dormancy
Crown grafts tend to remain in their resting phase longer than hairline grafts. It is common to see almost no new growth in the crown at month 3 when the hairline is already showing fine hairs. This is the period when many patients become anxious, but it does not indicate graft failure.
Months 5 to 9: Gradual Emergence
Crown growth becomes visible but remains patchy through this phase. Because the crown is viewed from above (often by the patient in a mirror), even moderate coverage can look sparse. The swirl pattern of natural crown hair also means that transplanted hairs need to reach a certain length before they lay correctly and provide visual density.
Months 10 to 18: Full Maturation
The crown continues filling in well after the hairline has reached its final result. Some patients see meaningful improvement between months 12 and 18 specifically in the crown area. Surgeons experienced with vertex transplants set this expectation from the start.
Factors That Influence Both Timelines
Several variables affect how quickly results appear in either zone:
- Graft count and spacing: Higher density placements may take longer to fully mature because follicles compete for blood supply during early healing
- FUE vs FUT method: Both achieve 90 to 95% graft survival, but FUE's smaller wound sites may allow slightly faster initial healing
- Post-operative medications: Finasteride (80 to 90% halt further loss) and minoxidil (40 to 60% regrowth) support transplanted and native hair when used alongside surgery
- Smoking: Nicotine constricts blood vessels and directly impairs follicle recovery. Smokers consistently show slower growth timelines
- PRP therapy: Platelet-rich plasma ($500 to $2,000 per session) may accelerate early growth when administered during or after the procedure

When to Be Concerned
Not all delayed growth is normal. Contact your surgeon if:
- You see zero new growth in the hairline after 5 months
- The crown shows no activity at all after 7 months
- You notice signs of infection (persistent redness, swelling, pus, or fever) at any point
- Large patches within the transplant zone remain completely bare while surrounding areas are growing
These situations are uncommon with experienced surgeons and proper aftercare, but early intervention improves outcomes when problems do occur. Learning about tracking graft survival rate can help you monitor your progress systematically.
Setting Realistic Expectations for Combined Procedures
If you had both hairline and crown work done in a single session, prepare for an uneven visual result during months 4 through 10. Your hairline will look noticeably better while your crown appears to lag behind. This is expected. Avoid judging your crown result before the 12-month mark, and ideally wait until month 15 to 18 before making any decisions about touch-up procedures.
84% of dissatisfied transplant patients cite unmet expectations as the primary cause of their disappointment. Knowing that the crown will trail the hairline by several months is one of the simplest ways to avoid joining that statistic.
Frequently Asked Questions
When will I see results after hair transplant?
Most patients see initial new growth between months 3 and 4. By month 6, roughly 50 to 60% of transplanted hairs are visible. Full results typically appear between months 12 and 18, with the crown often taking 2 to 3 months longer than the hairline to reach final density.
Is shock loss after hair transplant normal?
Shock loss is a normal part of the transplant process affecting 50 to 100% of transplanted hairs in the first 2 to 6 weeks. The follicles remain alive beneath the skin and enter a resting phase before new growth begins. Existing native hairs near the transplant zone may also temporarily shed.
How do I know if my hair transplant is working?
Early signs include small bumps or stubble appearing around month 3, followed by thin wispy hairs that gradually thicken. By month 6, you should see visible improvement. If you see no growth by month 8, consult your surgeon for a follow-up assessment.
