ABSTRACT This mixed-methods study examines the marketing of, and toxic ingredients found in, common personal care products (PCPs) such as shampoos or deodorants that are sold in the United States. Through qualitative analyses of the messaging presented by PCP packaging and quantitative analyses of the prevalence of toxic ingredients by product and target consumer, we reveal what we term “toxic personal care”: the usage of products sold to consumers as minimally necessary, and perhaps even beneficial, to their personal well-being through gendered messaging, yet introduce consumers to chemical toxicity. Supporting research on postfeminist sensibilities, we find that products marketed to women are no more likely to contain toxic ingredients than those marketed to men, nor do lower-priced products contain more toxic ingredients. Instead, product descriptions perpetuate a “cult(ure) of confidence” that not only encourages the usage of PCPs equally across women and men through drawing from traditional gendered stereotypes, but also masks the similarities in ingredients and toxins. These findings have implications for understanding consumption, well-being practices, gendered marketing, and constructions of confidence in the United States, including monetary and possible health costs to consumers.
