Efficacy of a Non-Comedogenic Hair Care Regimen for the Reduction of Mild-to-Moderate Truncal and Facial Acne: A Single-Arm 8-Week Study.

Abstract

Hair care products can be comedogenic, and therefore contribute to acne. Hair care products can leave a residue on the skin, even with rinse off products. This residue may explain why hair care products can cause acne. 27 subjects aged 16–45 with mild to moderate facial and truncal acne utilized a non-comedogenic hair care regimen for 8 weeks. Dermatologist assessment of acne severity was performed with the PGA (truncal acne) and IGA (facial acne) scale at baseline and 8 weeks. At 8 weeks 70% of subjects with truncal acne showed improvement in PGA, and 52% of subjects with facial acne showed improvement in IGA by dermatologist grading. Subject self-assessment corresponded with dermatologist grading, with 74% agreeing that their skin looks and feels healthier at 8 weeks. This non-comedogenic hair care regimen showed efficacy in improving mild to moderate truncal and facial acne, both by dermatologist grading and subject self-assessment. Hair care products should be considered as a possible contributor to acne. J Drugs Dermatol. 2021;20(6):690-693. doi:10.36849/JDD.5772.
