Terms of use

Free tools and information, offered as-is. Here's what that means precisely.

Not medical advice

Everything on this site — the staging tool, the quiz, the calculator and all written content — is cosmetic self-assessment and general information. None of it is medical advice, a diagnosis, or a substitute for consulting a doctor or licensed prescriber, and decisions about medication or surgery should always involve one. Sudden, patchy, or symptomatic hair loss in particular warrants medical attention rather than a staging chart.

Accuracy and warranty

The tools measure what the methodology page says they measure, and refuse where they cannot measure — but results depend on your photo, your answers, and a classification system that is itself a simplification. Cost figures are dated estimates of typical published pricing, not quotes. The site is provided as-is, without warranties of any kind, and Known by One, LLC accepts no liability for decisions made on the basis of its output.
