Hair Care Product Use among Women of Color

Trial Status: Active

This clinical trial aims to further understand hair care product use and knowledge among women of color. Phthalates are a common ingredient in hair care products and is a well-known endocrine disrupting chemical. Endocrine disrupting chemicals from the surrounding environment may influence the risk of breast cancer; especially when women are exposed to endocrine disrupting chemicals while their breast tissue is changing (such as during pregnancy and postpartum). Learning about the different chemicals in hair care products may help participants make informed decisions about which hair care products they use.
