AI strand detection
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.

DIAGNOSTIC
Norwood staging
Baldness Analysis
Upload a top-down scalp photo and our AI maps hair loss zones, estimates the Norwood–Hamilton classification stage, and highlights affected areas. Ideal for initial consultations, progress tracking, and patient education about pattern baldness severity.

Density Analysis
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.
