Hormone-Containing Hair Product Use in Prepubertal Children

Usage of Children’s Makeup and Body Products in the United States and Implications for Childhood Environmental Exposures

“…We found that a greater proportion of White children used CMBPs than Black children; however, the previous literature has reported greater usage of cosmetics among women and children of color [18,21].

A characterization of personal care product use among undergraduate female college students in South Carolina, USA

“…Across race categories, significant differences in the use of shampoo, conditioner, and body lotion was observed, suggesting the potential for differential EDC exposure within this cohort. Racial differences in PCP use have been reported in studies of specific hair product types that were not included in this survey (e.g., hormone-containing hair products; [28], oils, root stimulator, perm [29]), which further supports racial disparities in EDC exposure risk. The degree of chemical exposure for individuals that use PCPs and cosmetics depends on the types of products used [5,6,14,24], the quantity and frequency of product use [12,13,30], and the duration of use (i.e., leave-on vs. rinse-off [13]).…”

Androgenetic alopecia in children: report of 20 cases

A hyperinsulinaemic diet, environmental exposure to hormones, environmental sexual exposure and parental mood disorders have been considered as possible causes of early adrenarche 10–14 . In our children, the DHEA‐S levels were consistent with postadrenarche, but none of them was affected by premature puberty, as demonstrated by physical and laboratory assessments.…”
