AI hair analysis tools are designed primarily for androgenetic alopecia (pattern hair loss) and have significant limitations when assessing central centrifugal cicatricial alopecia (CCCA). Misdiagnosis of hair loss type leads to wrong treatment in approximately 28% of cases, and CCCA is one of the conditions most frequently confused with other types of hair loss in non-specialist settings.

Why AI Tools Struggle With CCCA
AI hair analysis, including the tool at myhairline.ai, uses facial landmark analysis and hairline pattern recognition optimized for the Norwood Scale. The Norwood Scale measures androgenetic alopecia, which follows predictable patterns of temple recession and vertex thinning driven by DHT sensitivity.
CCCA behaves differently in several important ways:
| Feature | Androgenetic Alopecia | CCCA |
|---|---|---|
| Pattern | Temple recession, vertex thinning | Central crown spreading outward |
| Mechanism | DHT miniaturization | Scarring inflammation destroys follicles |
| Reversibility | Partially reversible with treatment | Permanent once scarring occurs |
| Primary population | Males of all ethnicities | Primarily women of African descent |
| AI detection | High accuracy via Norwood staging | Low accuracy; does not fit Norwood patterns |
Specific AI Limitations for CCCA
Pattern Mismatch
CCCA begins at or near the vertex (crown) and spreads outward in a centrifugal pattern. AI tools trained on Norwood stages may misinterpret early CCCA as Norwood 3V (vertex variant) or Norwood 4, leading to incorrect graft estimates and treatment recommendations. The underlying pathology is fundamentally different.
Scarring Is Not Visible in Standard Photos
The hallmark of CCCA is follicular scarring, where destroyed follicles are replaced by scar tissue. This scarring is often subtle and requires dermoscopy (magnified scalp examination) to identify. A standard front-facing photo analyzed by AI cannot detect perifollicular erythema, loss of follicular ostia, or the "lonely hair sign" that dermatologists use to identify CCCA.
Ethnicity-Specific Considerations
Hair density varies by ethnicity. The average follicular unit density for individuals of African descent is 120 to 180 per square centimeter, compared to 170 to 230 for Caucasian patients. AI calibration based on broader population averages may overestimate or underestimate hair loss severity in CCCA patients.
Active vs. Inactive Disease
AI cannot distinguish between active CCCA (ongoing inflammation and follicle destruction) and burned-out CCCA (scarring complete, no active inflammation). This distinction is critical because treatment decisions, including whether a hair transplant is even possible, depend entirely on disease activity status.
What AI Assessment Can Do for CCCA
Despite these limitations, AI screening has some practical uses:
- Rule out androgenetic alopecia: If AI analysis shows a clear Norwood pattern, CCCA is less likely
- Track overall density changes: Serial photos analyzed over time can document progression, even if the specific diagnosis is not determined
- Prepare for specialist visits: AI-generated baseline measurements give your dermatologist objective data to compare against future assessments
The Correct Diagnostic Path for CCCA
If you suspect CCCA, follow this sequence instead of relying on AI alone:
- Run an AI screening at myhairline.ai/analyze to check whether your loss fits a Norwood pattern
- If AI cannot classify your pattern into a clear Norwood stage, suspect a non-androgenetic cause
- See a board-certified dermatologist experienced in scarring alopecias
- Expect dermoscopy and possibly scalp biopsy to confirm or rule out CCCA
- Begin treatment promptly if CCCA is confirmed, since early intervention preserves follicles that scarring would otherwise destroy permanently
