We read the trials so you can stop guessing.

01What this is

Most hair advice is sold, not reported. A clinic markets a treatment, a brand markets a serum, a forum repeats whichever claim arrived first. The reader is left holding a shelf of half-true statements and no way to rank them.

This site ranks them. Every article ends with a tier, from A to C, describing how much of the claim rests on controlled human evidence rather than mechanism, marketing or a single enthusiastic clinic.

We cover six questions per issue and no more. We would rather publish six pieces we have checked than sixty we have not.

02Who writes it

The desk is three people. One covers follicle biology and medical treatment, one covers ingredients and formulation, one covers procedures and their commercial incentives. None of us sells a product, runs a clinic, or takes a fee from a manufacturer.

We are not your dermatologist. Nothing here is a diagnosis, and a page cannot examine your scalp. What a page can do is tell you which questions are worth asking, which tests are worth paying for, and which treatments have survived a controlled trial.

03How claims are graded

A tier is attached to a claim, not to an article. One piece can hold an A for its central finding and a C for a secondary one, and we try to say which is which in the text rather than in a footnote.

Grade A requires randomised controlled data in humans, or a meta-analysis of it. Grade B requires at least one good trial or consistent cohort evidence. Grade C covers everything else: mechanism, animal work, small open-label series, and the entire category of claims that exist only in advertising.

If a claim cannot be graded, it does not get published. That single rule removes most of what the internet says about hair.

04Corrections

When we get something wrong we correct it in place and note the change at the foot of the article, with the date. Substantive corrections are never made silently.

If you believe an article misstates a finding, the most useful message quotes the specific sentence and names the primary source you think contradicts it. We read every one.

Send corrections to [email protected], with the article title in the subject line.

05Independence and funding

Hair Experts carries no advertising, no sponsored content and no affiliate links. We do not accept payment for coverage, review copies, or conference travel from manufacturers.

Where an article discusses a commercial category — a topical, a laser device, a clinic procedure — we name the category and the evidence, not a brand. If we ever accept funding, it will be disclosed on this page before it affects a single article.
