RESUMO
Introduction The over-the-counter (OTC) market for hair loss products, particularly those containing minoxidil, has significantly expanded due to the increased prevalence of hair loss. Minoxidil, a vasodilator medication, is known for its potential to stimulate hair growth. However, the rise in OTC formulations has led to misleading advertising and marketing, with some companies exaggerating the benefits of their products while minimizing potential adverse effects. Methods A Google Boolean Search was conducted to identify OTC minoxidil products. The topmost non-sponsored search engine result page was used for analysis. Products not containing any dosage of minoxidil were excluded, resulting in nine products. These were individually searched on Amazon and eight were analyzed for any addressed safety information and adverse effects profile. Results The analysis revealed that only two out of eight products (25%) reported safety information, and none of the products (0%) reported any adverse effects. Significant observations were found surrounding the transparency and accuracy of the advertising and marketing of these products. Many companies made bold claims about their products without providing supporting scientific evidence or studies. Furthermore, many of these OTC hair loss brands did not adequately mention and explain the adverse effects of the product. Conclusions The study highlights the need for greater transparency in the marketing of OTC minoxidil products. Companies should provide clear and accessible information about the safety and potential adverse effects of their products. This will empower consumers to make informed decisions and foster trust between the industry and the consumer. Furthermore, the authenticity and accuracy of marketing images should be ensured to avoid giving false hopes to consumers.
