Core principles
The quiz is designed to help users organize observations before a more complete clinical discussion. It does not confirm a diagnosis, replace laboratory testing, or rule out uncommon causes of hair loss.
Signals considered
The question flow looks for common features linked to androgenetic alopecia, telogen effluvium, alopecia areata, traction alopecia, thyroid-related shedding, and nutrition-related context.
- Pattern location such as frontal line, crown, margins, or diffuse shedding
- Timing and pace of visible change
- Trigger history such as illness, stress, postpartum change, weight change, or medication changes
- Styling and routine clues that may increase tension or breakage risk
- Associated observations such as patch shape, scalp symptoms, or broader systemic context
How scoring works
Answers are mapped to heuristic pattern scores. Higher scores indicate a stronger educational match between the answer pattern and a known category, but they are not a measure of diagnosis certainty.
The result page ranks the strongest matches first, adds short evidence notes, and then provides educational next steps before any sponsored options are shown.
Limits of the quiz
Hair Quiz cannot examine the scalp directly, assess laboratory values, evaluate unusual scarring processes, or replace a clinician’s full history and examination.
