7 free tools

Tools that show their working.

Nothing here diagnoses you, asks for your email, or sells you a subscription. Every number these tools print is quoted from one of our guides, and shown with the sentence and the guide it came from, so you can disagree with the source rather than with us.

340 quoted figures across 7 tools. A tool that cannot trace a number to a published sentence fails the build rather than shipping the number.

Diagnosis & Testing

Blood-Test Request Builder for Hair Loss

Tick your symptoms and get the blood tests our guides say are worth asking for — core panel, add-ons, timing notes — as text you can hand to a doctor.

Self-assessment

Receding or Maturing Hairline? Check It Feature by Feature

Compare what you can see at your temples against the features our guides use to separate a maturing hairline from early pattern loss. Not a diagnosis.

Shedding

How much shedding is normal?

Place your hair count against the published 50-100 a day range, corrected for how you counted and how long since your last wash. Shows the working, not a verdict.

Interactive

Shedding Timeline Projector

Published telogen effluvium windows on your own calendar: when shedding typically starts, peaks and stops after childbirth, COVID, surgery or illness.

Interactive

Treatment Evidence Explorer

Side by side: what the published trials measured for each hair-loss treatment — response rate, n, side-effect rate, time to result. Not a recommendation.

Interactive

Five-Year Cost Comparator

What a hair-loss regimen actually costs over one year and five, built only from the price ranges our guides publish. Ranges, not a single invented figure.

Interactive

Hair loss treatment timeline: month by month, from your start date

Put the published milestones for finasteride, minoxidil, oral minoxidil, dutasteride or the combination on a calendar anchored to the day you started.
