Can shampoo, lotion, or fragrance add to endocrine-disruptor exposure during pregnancy?
caution
Short answer
Yes. Shampoo, lotion, fragrance, and other personal care products can add to endocrine-disruptor exposure during pregnancy.
The main issue is repeated daily use, especially leave-on products and heavy fragrance. One shower is not the problem.
Why this matters
Pregnancy is a time when hormone signals matter. Personal care products can involve phthalates, phenols, PFAS, parabens, and related chemicals.
You do not need to replace everything at once. Start with the products used most often and left on skin the longest.
What the research says
A 2026 Environment International evidence map reviewed studies on personal care product exposure and fetal growth. Phthalates and phenols were the most studied chemical groups.
A 2026 Environmental Research study found associations between emerging endocrine-disrupting chemicals and thyroid hormone changes in pregnant women. A 2026 Ecotoxicology and Environmental Safety study linked personal care product metabolites with lower thyroid hormone measures in adults.
What to do instead
Use fewer products. Choose fragrance-free when possible. Avoid unnecessary leave-on scent during pregnancy.
If shampoo is a daily product for you, simplify that first. Then look at lotion, perfume, hair spray, and scented body products.

What to use instead
If shampoo is one of your daily products, a simpler shampoo bar can be a practical first swap.
