About this study

Official title: You Have the Right to Know: Empowering Women Through Clean Beauty Research and Education

Every day, consumers use personal care products containing thousands of manmade chemicals. Growing evidence suggests that personal care products specifically marketed to Black women (e.g., hair straighteners and oils, skin lighteners) often contain potentially hazardous chemicals that can interfere with hormones or increase cancer risks. This research focuses on how the investigators can educate and activate community members in Newark, NJ to reduce disparities in exposures occurring through hair products. Leveraging educational clean beauty events hosted by collaborators at Clean Water Action, the investigators will administer surveys on hair product use and attitudes immediately before and after a clean beauty educational intervention. Participants will also complete surveys 3 months post-event to examine any changes in attitudes or behaviors around hair products and their use and safety.

Read the detailed description

The investigators will evaluate hair product perceptions, knowledge, and use among community members before and after an educational intervention. At the beginning of Clean Beauty events hosted by Clean Water Action, the investigators will collect survey data on hair product use as well as knowledge and perceptions around product safety from attendees. The investigators will administer a post-workshop survey to evaluate changes in knowledge and perceptions from pre- to post-workshop. Three months after the workshop, the investigators will distribute a follow-up survey to examine whether the intervention had sustained impacts on hair product perceptions, knowledge, or use.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Chemical Exposure PreventionBehavioural

    Education on potential toxic chemicals found within personal care products and safer alternatives during community-engaged clean beauty events.

Study groups in NCT07216898
Study groupRoleWhat they receive
Clean Beauty Event AttendeesParticipants in clean beauty events will be educated on the risks of toxic chemicals in personal care products and safer alternatives. They will be invited to provide information on their personal care product use and buying habits immediately before and after the educational events. Three months after the events, participants will complete surveys on any sustained changes in product use behaviors.
Receives: Behavioral: Chemical Exposure Prevention

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary outcome is any intended changes in participants' hair routines from pre to post event

    After the Clean Beauty intervention event, participants will be asked, "Based on what you learned today, do you think you will make any changes to your hair style, hair routine, or the products you use?" [Answer choices: Yes/No/Not sure] We will calculate the percentage of participants who plan to make a change in their hair routine.

    Measured: The outcome will be assessed immediately post-event (1-2 hours after baseline).

Secondary outcomes (1)

  1. Perceptions of hair product safety following the Clean Beauty intervention event.

    Our main secondary outcome is changes in perceptions around hair product safety from before the Clean Beauty intervention event to three months after the event. Prior to the event, at baseline, participants will be asked the extent to which they agree with the statement that "The hair products I use affect my health" (Answer choices: Strongly disagree, disagree, neither agree nor disagree, agree, strongly agree). The question will be repeated in a three month follow-up questionnaire. We will look at changes from baseline to the three month follow up.

    Measured: Changes in perceptions around hair product safety will be evaluated 3 Months after baseline.
