# Trichometrics

> Trichometrics is an AI-powered hair-loss tracking app (iOS, Android, web) that scans your scalp, scores hair density, thickness, and your Norwood stage, and tracks whether treatments are working over time. The site also publishes evidence-based, medically-reviewed guides on hair loss causes and treatments, each citing peer-reviewed research (PubMed/PMC, AAD, NHS, StatPearls).
