Hair follicle regeneration from severe burns is impossible after deep dermal damage, making accurate boundary mapping essential for determining which scalp areas can support treatment and which represent permanent loss. Tracking documents the exact extent of damage and monitors recovery in surrounding tissue.
Understanding Burn-Related Hair Loss
Scalp burns destroy hair follicles at different depths depending on the severity of the injury. The depth of thermal damage determines whether follicle recovery is possible.
| Burn Degree | Depth | Follicle Impact | Recovery Potential |
|---|---|---|---|
| Superficial (1st degree) | Epidermis only | Temporary inflammation | Full recovery in 2 to 4 weeks |
| Partial thickness (2nd degree) | Into dermis | Some follicle damage | Partial recovery possible |
| Full thickness (3rd degree) | Through dermis | Complete follicle destruction | No natural recovery |
| Deep (4th degree) | Into subcutaneous tissue | Complete destruction with scarring | No natural recovery, scar tissue forms |
For partial thickness burns, tracking over 3 to 6 months reveals which follicles survived the injury and resumed growth. For full thickness burns, tracking confirms the permanent boundary and documents the treatment-eligible zone surrounding the scar.
Step 1: Wait for Scar Maturation
Do not begin tracking immediately after a burn injury. Scar tissue takes 6 to 18 months to mature fully. During maturation:
- The scar transitions from red and raised to pale and flat (in most cases)
- The boundary between scarred and healthy tissue stabilizes
- Blood supply to the scar margin establishes its final pattern
- Surrounding follicles either recover or confirm permanent damage
Begin tracking once your dermatologist or burn specialist confirms the scar has matured. Premature tracking produces unreliable boundary data because the injury zone is still changing.
Step 2: Photograph and Map the Scar Boundary
Once the scar is stable, create your baseline documentation:
Photography protocol for scarred areas:
- Part or shave surrounding hair to expose the full scar boundary
- Photograph from directly above at a fixed 30 cm distance
- Include a ruler or reference marker in the frame for scale
- Take overlapping photos if the scarred area is larger than your camera's field of view
- Photograph the entire circumference of the scar, not just the most visible section
Upload these photos to myhairline.ai. The AI density analysis creates a density map that shows the stark contrast between scarred zones (0 to 5 follicular units per square centimeter) and healthy surrounding tissue (35 to 50+ follicular units per square centimeter).
This density map serves as your scar boundary reference. Save it and share it with any hair restoration surgeon you consult.
Step 3: Assess Treatment-Eligible Zones
Not all scarred tissue can receive hair transplant grafts. The factors that determine transplant viability in scar tissue include:
Blood supply: Grafts need adequate vascularization to survive. Well-vascularized scars (pink or slightly red coloring, soft texture) can support transplantation. Pale, avascular scars may not.
Scar thickness: Thin scars allow grafts to anchor and establish blood supply. Thick hypertrophic or keloid scars create a hostile environment for graft survival.
Scar stability: The scar must be fully matured and not actively contracting. Tracking confirms stability by showing no boundary changes over 3 to 6 months.
Surrounding donor density: Hair transplant into scar tissue uses the same donor supply as standard procedures. FUE harvests individual grafts from the donor zone, with survival rates of 90 to 95% in healthy scalp. In scar tissue, survival drops to 50 to 70%, so more donor grafts are needed per square centimeter of coverage.
Step 4: Track Trial Transplant Results
Most experienced surgeons recommend a trial transplant before committing to full scar coverage. This involves placing 50 to 100 grafts into the scar margin to assess survival in the specific scar tissue.
Trial transplant tracking timeline:
- Baseline: Photograph the trial area before graft placement
- Week 1: Document initial healing and graft anchoring
- Month 1: Shedding phase. Density readings will drop temporarily
- Month 3: Early new growth from surviving grafts
- Month 6: Count surviving grafts. Calculate survival percentage
If the trial shows 60% or higher graft survival, full coverage is typically feasible. Below 40%, the scar tissue may not support meaningful coverage and alternative approaches (scalp micropigmentation, hair systems) should be considered.
Step 5: Monitor Full Procedure Recovery
If the trial succeeds and you proceed with full scar coverage, tracking follows the standard hair transplant timeline but with adjusted expectations.
For reference, standard FUE recovery takes 7 to 10 days and produces 90 to 95% graft survival. Scar tissue procedures require:
- Longer initial recovery: 10 to 14 days due to reduced blood flow in scar tissue
- Slower growth emergence: First visible growth at 4 to 5 months instead of 3 to 4
- Lower final density: Expect 15 to 30 follicular units per square centimeter in scarred areas compared to 35 to 50 in healthy scalp
- Multiple sessions: Most scar coverage requires 2 to 3 transplant sessions spaced 9 to 12 months apart
Track each session independently. Upload photos monthly and compare density readings to the pre-procedure scar baseline, not to healthy scalp density. The goal is meaningful coverage improvement within the scar, not restoration to pre-injury density.
Tracking Non-Surgical Options
Not all burn scars require surgical intervention. For smaller scars or patients who prefer non-surgical approaches:
Scalp micropigmentation (SMP): Creates the appearance of hair follicles using tattooed micro-dots. Tracking photographs document the aesthetic result over time, as SMP can fade and require touch-ups every 3 to 5 years.
Scar revision surgery: Dermatological scar revision can narrow the scarred zone, reducing the area that needs coverage. Track the scar boundary before and after revision to document the reduction.
Topical treatments: Silicone sheets and pressure therapy can flatten raised scars, potentially improving the surface for future transplantation. Monthly tracking during scar treatment documents the textural changes.
Presenting Your Data to Specialists
Your tracking data package for a burn scar consultation should include:
- Scar boundary density map from the initial assessment
- 3 to 6 months of stability data confirming the boundary is not changing
- Trial transplant survival data (if completed)
- Donor area density assessment showing available supply
This documentation gives the surgeon objective measurements to plan the procedure, estimate graft requirements, and set realistic expectations for coverage density.
Begin Documenting Your Scar Boundary
Accurate mapping is the first step toward informed treatment decisions for burn-related hair loss. Upload your scar area photos at myhairline.ai/analyze to generate your density boundary map and establish the baseline for your recovery documentation.
