The Utilization of YouTube as a Resource on Hair Loss Treatments.

To the best of our knowledge, no previous studies have evaluated the quality of videos discussing hair loss treatments METHODS: YouTube was searched on December 10, 2019, using the relevance and view count filters for the following search terms: hair loss treatment, baldness, alopecia, male pattern baldness, and female pattern baldness. The DISCERN criterion for assessing consumer health information was used to evaluate each video. A score of 1 indicates a low overall video quality, whereas a 5 indicates a high-quality source of information for patients. The DISCERN treatment assessment is a validated tool to assess the quality of patient information about treatment choices. Two-sample t tests and Mann-Whitney U tests were used to determine significance. We analyzed 90 videos receiving a total of 108,240,496 views with a mean view count of 1,202,672 views per video (Table 1). Pharmaceuticals including minoxidil and finasteride were the most commonly mentioned treatment (30% of videos) followed by nutraceuticals (20%). YouTube influencers (Table 2) represented 37.8% of authors followed by companies/advertisers (15.6%). Seventeen videos (18.9%) included board-certified dermatologists. The mean DS overall was 2.66, and the mean DS for bias was 2.98. Our data demonstrate the extensive use of YouTube for hair loss treatment information. While YouTube can be a valuable resource for patients, videos are often biased and can misinform patients. Moreover, the lack of a central review process or governing body to validate claims made in videos can be a safety concern.
