Estrogen and endocrine-disrupting chemicals (EDCs) that are associated with several health outcomes have been found in hair products. We evaluated the proportion, frequency, duration, and content of hair products in a racially/ethnically diverse population. We recruited n = 301 African-American, African-Caribbean, Hispanic, and white women from the New York metropolitan area. We collected data on hair oil, lotion, leave-in conditioner, root stimulator, perm, and other product use. Estrogen and EDC information was collected from commonly used hair products’ labels (used by >3% of population). African-American and African-Caribbean women were more likely to use all types of hair products compared to white women (P < 0.0001). Among hair product users, frequency varied significantly by race/ethnicity, but not duration. More African-Americans (49.4%) and African-Caribbeans (26.4%) used products containing placenta or EDCs compared to whites (7.7%). African-American and African-Caribbean women were more likely to be exposed to hormonally-active chemicals in hair products.
