We buy the tools, use them for weeks, and check the claims against the research.
Hands-on reviews of scalp-care and hair-growth tools, scored against criteria we publish in advance — next to plain-language summaries of what the studies actually show.

Latest research summaries
Editorial, evidence graded
The first research summaries are being written and reviewed.
How we grade evidence
Strongest at the top. What each level means
Level 6 of 6
Meta-analysis
Pools the results of several studies, usually randomized trials.
Level 5 of 6
Randomized controlled trial
People are randomly assigned to a treatment or a comparison, which limits bias.
Level 4 of 6
Clinical study
Tests a treatment in patients, but without full randomization or control.
Level 3 of 6
Observational study
Looks for links in existing data. Shows association, not cause.
Level 2 of 6
Expert opinion
Based on clinical experience and guidelines rather than new data.
Level 1 of 6
Anecdotal
Individual reports or common practice, not formal research.
