What do HairBase evidence badges mean?

💡 Quick answer

A green chip is not a diagnosis. Photograph; read sources on the treatment page.

Proven / promising / unproven is a map for readers, not an FDA letter. We do not invent PMIDs to move a chip. Related: evidence-tiers-hair — different URL.

Do not start oral finasteride because a badge was green. Do not double minoxidil because a badge was grey.

Red-flag symptoms skip badges. This is not medical advice.

Not medical advice. General education only; it does not replace diagnosis or treatment by a licensed professional. Figures such as 1 mg or 5% are labelled strengths you may see in your country — not a dosing instruction. Consult a board-certified dermatologist before starting, stopping or changing any treatment.

⚠️ When to see a doctor — don’t self-treat

  • Sudden patchy or circular bald spots
  • Redness, scaling, pus, pain or itch (possible scarring alopecia — treat urgently)
  • Broken hairs or rapid loss
  • Loss with body-wide signs (weight loss, fatigue, cycle changes, acne, extra hair)
  • Loss right after a new medication
  • Any hair loss in a child
