How we write

This is not medically reviewed

A great many health sites carry a badge saying their content is "reviewed by board-certified physicians". We do not, because it would not be true. No doctor reviews these pages.

What we do instead is show our work. Every guide ends with a numbered source list — mostly PubMed and PubMed Central, systematic reviews and randomised trials where they exist, plus guidance from the American Academy of Dermatology. Where a claim rests on a single small study, the guide says so. Where the evidence is genuinely poor, the guide says that too, which is more often than the supplement industry would like.

We would rather be a well-sourced reference that tells you its limits than an unsourced one that borrows authority it has not earned.

What we do not do

• We do not diagnose. Several conditions covered here look identical in a mirror and are distinguished by a dermatologist, sometimes with a biopsy. The guides tell you when that is the case.
• We do not prescribe. Finasteride, dutasteride and spironolactone are prescription medicines with real side-effect profiles. We describe what the trials measured. Deciding whether that applies to you is a conversation with a doctor.
• We do not sell treatments. There is no clinic behind this, no consultation to book, and no house-brand supplement.

Corrections

Medicine moves and mistakes happen. If a figure here disagrees with the study it cites, the study is right. Tell us and we will fix it, and say that we did.

On how these were produced

These guides were drafted with AI assistance from the cited literature and then checked against their sources. We think being straightforward about that is part of being trustworthy, particularly on a subject where readers are deciding whether to take a drug. It is also why the citations matter so much: they are how you verify what you are reading, whoever wrote it.
