Guide to Growing Hair Red light, hair loss, and the evidence

The site

Editorial standards

Who publishes this guide, and the rules a page has to meet before it goes up.

We compare hats using manufacturers’ published specs, prices and the clinical research, and we don’t earn commission on links. How we review.

Editorial standards at Guide to Growing Hair mean every figure comes from a primary source we link, every price carries the date it was checked, and health claims stay inside what the trials support. The site is published as Guide to Growing Hair until a legal name is confirmed, and it is not run by RedLight Innovation. We do not invent ratings, testimonials or results.

Who publishes Guide to Growing Hair?

Guide to Growing Hair is the publisher name on every page, in the footer and in the site’s structured data. It is a placeholder for the operating company. The legal name, email, registered office and company number are not confirmed, so they are not printed. The site is not run by RedLight Innovation, CurrentBody, HigherDOSE or Beauty Pie. The longer note is about this guide.

How does a page earn a factual claim?

A price, a wavelength, a session time, a fit range or a stock status comes from the brand’s own page, and the comparison table says when prices were checked. A hair-loss claim comes from a paper, the NHS, or a GOV.UK page, with the link in the sentence or in the sources. If a page is silent, we say the figure was not stated. We do not borrow it from a retailer, a video or an older version of the page.

What must a new page include?

Every article opens with a direct answer to its question, then key takeaways. Each section heading is a question, with a short answer in the first paragraph. The page lists common questions, links to related questions, and names its sources. The content file has to include a title, a description, that direct answer, the questions, the sources and a modified date. The build fails if any of those are missing. The working method, including what we will not invent, is how we review. Money and commercial relationships are on the editorial policy.

How do you correct a page?

Send the URL, the figure and the date you saw it, once a public address is on the contact page. Questions about your own hair are for a GP, not for this guide.

Common questions

Who is responsible for Guide to Growing Hair?

The company that operates the site. Until its legal name is confirmed, every page names the publisher as Guide to Growing Hair. RedLight Innovation does not run the site.

How are facts checked?

A device figure has to be on the brand’s own page. A health claim has to be in a paper or an NHS or GOV.UK page we link. If the figure is missing, the page says it was not stated.

Do you use star ratings or testimonials?

No. We do not award stars, invent quotes, or present photographs as customer results. The method is on the how we review page.
