Hair Density Analysis
Measure scalp coverage with calibrated hairs-per-area density mapping.

Overview
Density analysis goes beyond raw counts by calculating hairs per square centimeter (or mm²) across the scanned region. Enter your image scale or use our calibration tools to get clinical-grade density metrics used in transplant planning and hair loss staging.
What You Get
Key Features
- Automatic hairs-per-cm² and hairs-per-mm² calculation
- Compare density across different scalp regions
- Assess donor area suitability for transplant procedures
- Track density improvements during treatment programs
- Export density metrics for patient records and reports
- Combine with visit tracking for longitudinal charts
Who Uses It
Transplant Surgeons
Evaluate donor density before harvesting and plan graft counts.
Dermatologists
Objectively measure whether topical or oral treatments increase density.
Hair Restoration Centers
Show patients measurable before/after density improvements.
Research Trials
Standardize density endpoints across multi-site clinical studies.
Image Guidelines
- Provide accurate image scale (cm or mm per pixel) for calibration
- Capture a consistent area size across follow-up visits
- Use the same scalp location each time for valid comparisons
- Avoid overlapping hair that obscures the scalp surface

Hair Counting
Our core hair counting model detects every visible strand in micro-camera or dermatoscope images. It groups hairs into follicular units (1–7 hairs) and returns an annotated image with confidence scores — the foundation for density tracking, transplant planning, and treatment monitoring.
