Do personal care products like shampoo or lotion increase the risk of endocrine disruption in pregnant women?
Yes. Research shows that chemicals found in common personal care products are linked to hormonal imbalances and risks to fetal growth during pregnancy.
What's actually in it
Personal care products like shampoo, lotion, and body wash often contain chemicals of emerging concern. These substances are designed to improve texture, scent, or shelf life, but they don't just sit on your skin. They can be absorbed into your body.
According to a 2026 study in J Hazard Mater, these hygiene products act as a source of exposure for vulnerable populations, including pregnant women. These products often contain chemicals that interfere with your body's natural hormone systems.
What the research says
The science is clear that what you put on your body can impact your health and your baby's development. Peer-reviewed research has identified specific risks associated with these exposures.
A 2026 study in Environ Res found that emerging hormone-disrupting chemicals are linked to changes in thyroid hormone levels in pregnant women. Your thyroid is critical for a healthy pregnancy, and these chemicals can disrupt its normal function.
Furthermore, the impact extends to the baby. A 2026 study in Environ Int mapped the evidence on this topic and confirmed an association between exposure to personal care products and risks to fetal growth. These findings highlight why it is important to be aware of the ingredients in your daily routine.
