PubMed 40176994 · doi:10.1159/000541809
What was done
The authors conducted a qualitative review to assess online misinformation related to alopecia. The abstract does not report search methodology, platforms evaluated, inclusion criteria, or specific review parameters.
What was found
The abstract reports no numerical data. It identified common themes of misinformation, including false causes such as headwear, haircare, and sexual practices; criticism of conventional therapies such as minoxidil, finasteride, topical corticosteroids, ciclosporin, methotrexate, and Janus kinase inhibitors; and promotion of unproven alternative remedies including mineral supplements, biotin, B vitamin complexes, fish oils, shark cartilage, onion juice, rosemary oil, horsetail extract, and saw palmetto.
Why it matters
Recognizing prevalent online myths enables clinicians to proactively address false hair loss causes and debunk unfounded remedies during clinical consultations.
Limits
No quantitative metrics, sample size, or systematic search protocols were reported in the abstract. The study relies on qualitative narrative synthesis and does not measure actual clinical outcomes or patient adherence.
