Use of certain personal care products during pregnancy may impact maternal hormone levels, according to a new Rutgers study.

 

Personal care and beauty products contain several ingredients that often include a wide range of endocrine-disrupting chemicals like phthalates, parabens, phenols, parabens and toxic metals. These chemicals interact with hormone systems, influencing synthesis, regulation, transport, metabolism and hormone reception, which are all especially vulnerable during pregnancy.

The researchers found that the use of hair products, particularly hair dyes, bleach, relaxers and mousse are associated with lower levels of sex steroid hormones, which have a critical role maintaining pregnancy and fetal development. Disruptions of these hormones may contribute to adverse maternal and pregnancy outcomes like growth restriction, preterm birth and low birth weight.

 

“Alterations in hormone levels, especially during pregnancy, can have vast consequences beyond health at birth including changes in infant and child growth, pubertal trajectories and may influence development of hormone-sensitive cancers such as breast, uterine and ovarian cancer,” says the study’s lead author, Zorimar Rivera-Núñez, an assistant professor at the Rutgers School of Public Health. “Additional research should address the public health impact of exposure to chemicals in hair products in pregnant populations.”

 

The researchers also found that socioeconomic variables, such as income, education and employment status, influence the use of personal care products among pregnant women in Puerto Rico. For example, participants who reported a household income greater than $100,000 use personal care products more often than participants with lower household incomes. Additionally, employed participants reported using more cosmetics than those who were unemployed.
