You report
The change, in context
When you noticed it, where it appears, and your family, health, sleep, stress, nutrition and scalp context. The Index uses your answers as reported signals, not confirmed causes.
Your answers are not a medical diagnosis.
Photos may show
A visible pattern
A report requires approved front and crown photos plus separate consent to remote analysis. They may add visible pattern or scalp-surface observations, not a follicle count or proof of why hair changed.
A scan cannot confirm miniaturization, DHT activity or a condition.
