    TLDR Hair, skin, and nails supplement use nearly doubled from 2011 to 2020, with higher usage among young adults, females, and certain ethnic groups.
    The study analyzed data from the National Health and Nutrition Examination Survey (2011-2020) to examine trends in hair, skin, and nails (HSN) supplement use among 40,959 participants. It found that 3.9% reported past-month HSN supplement use, with higher usage among younger individuals (20-39 years old), females, Black and Hispanic/Latino individuals, and those with more than a high school education. The use of HSN supplements nearly doubled from 2.5% in 2011-2012 to 4.9% in 2017-2020. Despite their popularity, HSN supplements pose significant risks, including biotin interference with medical tests and the presence of heavy metals in some products. The study highlights the need for dermatologists to be aware of these risks and to guide patients accordingly. Limitations include self-reported data and the inability to examine specific supplements or reasons for use.
