Description
Wang, Mahalingaiah and their co-authors study personal care product use and menstrual cycle traits in a US digital cohort, listed for 2026. Many such products hold chemicals that can disrupt hormones, yet links to cycle health are little known.
Thousands of participants reported product use over the past year, age at first use and whether they avoided certain ingredients. Logged cycle data added tens of thousands of cycles. Frequent use and childhood start for several products linked to very long, very short or irregular cycles. People who avoided named harmful ingredients reported more regular cycles. Effects were stronger in some health and age groups.
