Disclaimer
What this site is not, stated once and clearly, before you act on anything you read here.
01Not medical advice
The content on this site is journalism about published research. It is not medical advice, diagnosis or treatment, and it does not create a doctor-patient relationship.
Do not start, stop or change any treatment on the basis of an article here. Speak to a qualified clinician who can examine you and take a history. That is a different activity from reading, and it is the one that produces a diagnosis.
02Results differ between people
Studies report averages across populations selected by criteria you have not been measured against. A treatment that produced a mean improvement of twelve hairs per square centimetre may do nothing for you, or considerably more.
Where an article gives a percentage, it is the figure from the cited trial, not a prediction about your outcome.
03When to seek care instead
See a clinician promptly if you have sudden patchy hair loss, scalp pain, scaling with pus or crusting, hair loss with fever, or loss accompanied by joint pain, rash or fatigue. These patterns point to conditions where delay changes the outcome.
Sudden diffuse shedding after illness, surgery or childbirth is usually self-limiting, but it should still be assessed if it persists beyond six months.
04Products and claims
We describe product categories and the evidence attached to them. We do not test products, and we do not verify that a given bottle contains what its label states.
Where a claim is graded C, that grade means the evidence behind the claim is weak. It does not mean the product is harmful, and a grade A does not mean a specific brand is trustworthy.
05Procedures
Surgical and injectable procedures carry risks that no article can fully enumerate for your case. Candidacy, technique and aftercare are clinical judgements.
Costs and outcomes quoted on this site are typical ranges reported in published series, not quotations. Always ask a treating clinician for their own complication rate and revision policy in writing.
06External content
We link to journals, regulators and other publications. We do not control them, we do not endorse their content, and we are not responsible for their accuracy or their privacy practices.
07No warranty
The site is provided without warranty of any kind. To the fullest extent permitted by law, we exclude liability for any loss arising from use of, or reliance on, its content.
08Reporting an error
