Abstract
BACKGROUND: Alopecia is common and can lead to significant distress for patients. Patients often seek medical information on the Internet, which may leave them susceptible to misinformation from poor-quality sources. The aim of this study was to qualitatively assess misinformation available online related to alopecia. SUMMARY: Several alopecia-related myths were identified, including false causes, criticism of conventional treatments, and bogus "natural" cures or remedies. False causes included headwear, haircare practices, and sexual practices. Treatments which were criticized included minoxidil, finasteride, topical corticosteroids, ciclosporin, methotrexate, and Janus kinase inhibitors. Alternative unfounded therapies which were touted included mineral supplements, biotin, B vitamin complexes, fish oils, shark cartilage, onion juice, rosemary oil, horsetail extract, and saw palmetto. KEY MESSAGES: Misinformation related to alopecia is prevalent online and may lead to suboptimal therapeutic outcomes. Dermatologists and other healthcare professionals should combat misinformation when encountered.
