    TLDR About 15% of US Army personnel use hair products containing hormone or placenta, with higher usage among non-whites, females, and enlisted personnel.
    In 2002, a study involving 2,097 US Army personnel investigated the use of hair products containing hormone or placenta, linked to premature sexual development. It was found that 14.8% of the subjects used these products. Usage was higher among non-whites (27.0%) than whites (6.3%), and higher among females (24.6%) than males (8.7%). Enlisted personnel (18.7%) were more likely to use these products than officers (7.3%). The highest usage was among non-white female enlisted personnel (43.6%) and the lowest among white male officers (2.0%). Additionally, 13.4% of respondents' children used these products, with usage patterns mirroring those of their parents. Despite federal regulation, the use of these hair products remained common.
