Why this blog exists

Hair loss is common, and the advice around it is loud. Product pages, forums and short videos tend to promise more than the research supports, while the useful information sits in journal papers and clinical guidance that few people have time to read. Hairline Journal tries to close that gap with plain explanations of what is known, what is still uncertain and when it is worth seeing a doctor.

Who writes it

The journal is run by a small editorial team. Posts are written and checked by the editors, and we do not publish under individual bylines. We are not a clinic and we do not sell treatments, supplements or hair products. No company pays for coverage, and we do not use affiliate links.

How each post is researched

  1. We start from the question a reader is likely to have, such as how much shedding is normal or how long a treatment takes to show results.
  2. We look for the strongest sources available: clinical guidelines, systematic reviews, randomized trials, regulator documents and pages from professional bodies such as dermatology associations.
  3. Every figure in a post, including numbers of hairs, percentages, months and doses, is checked against the source it comes from. Sources are listed and numbered at the end of every post.
  4. A second editor reads the draft against those sources before it goes up, and removes anything the sources do not support.
  5. We revisit posts when guidance changes and update the date when we do.

What we do not do

We do not diagnose, and nothing on this site is a substitute for an examination. Hair loss has many causes, some of which need blood tests or a scalp examination to tell apart. If your hair loss is sudden, patchy, or comes with itching, pain, redness or scarring, please see a doctor or dermatologist.
