Five disciplined steps.One honest answer.

Before anything else, structured questions a clinician would ask: pattern, onset, scalp symptoms, triggers, treatments. If your answers include warning signs — patchy loss, inflammation, sudden shedding — HairProof stops and says a licensed professional should look first. Your answers autosave and can be exported for that appointment.

Guided capture walks you through seven views — hairline, temples, sides, top, and crown — with framing overlays and lighting checks. For the angles you can't see, a voice countdown fires the shutter, or hand the phone to a helper. Blurry, dark, or badly framed photos are rejected on the spot with instructions to retake, because an unmeasurable photo would poison every later comparison.

Whatever you and your clinician choose — minoxidil, finasteride, devices, PRP, supplements, or nothing — log doses, side effects, shedding, and spend in about thirty seconds a day. Severe side effects trigger immediate plain-language guidance, never a buried warning.

Each follow-up scan reproduces your baseline conditions. The comparison engine first checks whether two scans are actually comparable — angle, lighting, framing. Below the 65% comparability gate, it refuses to draw a conclusion and tells you exactly how to retake. Only matched photos are ever compared.

Plain language, region by region: improving, stable, worsening — or honestly uncertain — with the confidence of every finding stated. It never diagnoses and never promises regrowth. Export it as a PDF built for a dermatologist's desk: months of standardized history they never usually get.
