Summary
Brief summary (as posted)
The purpose of this study is to reduce use of personal care products that contain endocrine disrupting chemicals among women. For this pilot intervention, the investigators focus on the hair care product class of personal care products, the reduction in use of phthalate-containing Hair Care Products (HCPs) and use among pregnant Women of Color (WOC).

Primary outcomes (2)
- measure
- Change in Internal Dose of Urinary Phthalate Metabolites
- timeFrame
- Baseline (early Trimester 3 i.e. week 27-31 of pregnancy) and Follow up 1 (late Trimester 3 i.e. 4-6 weeks post baseline)
- description
- Urinary phthalate metabolites will be measured through gas chromatography-mass spectrometry (GC-MS). The percent change will be calculated from baseline to follow up 1 (FU1) and presented as a summary value of all low molecular weight phthalates (sumLMW). This outcome is calculated from the \[(mean of FU1 - Mean of Baseline)/Mean of FU1\]\* 100. To calculate the sumLMW the investigators divided each metabolite by its molecular weight, summed the metabolites together, then multiplied by the average molecular weight of the metabolites.
