The TRI team will be attending the SCC80 Annual Meeting & Showcase next month in LA. Shamish Ganpule (Principal Research Associate, TRI) will present in Day 1 (Session E) on Effect of Dry Shampoo Usage on Scalp Microbiome: A Paired, Real-World Intervention Study. Other members of the team will be present at the Showcase exhibition and presenting posters with more of our research findings. Come and find us and see how TRI can help with your cosmetic claims testing and research.

Effect of Dry Shampoo Usage on Scalp Microbiome: A Paired, Real-World Intervention Study
The scalp microbiome contributes to scalp health, yet little is known about how commonly used hair care products influence microbial communities under real world conditions. This study will evaluate the effect of dry shampoo on scalp microbiome composition using a paired intervention design. Twenty participants (10 male, 10 female) sampled after a standardized 24hour no wash period and again 24 hours after application of a commercially available dry shampoo. Microbiome profiles characterized using 16S rRNA V3–V4 amplicon sequencing, with paired statistical analyses used to assess changes in taxonomic abundance and community diversity. The study will determine whether dry shampoo use is associated with within-subject shifts in key scalp-associated taxa and diversity metrics, while examining inter-individual variability and potential sex related differences. This work will provide a controlled framework for evaluating product-induced changes in scalp microbial ecology and may inform the development of microbiome conscious haircare products under realistic everyday use conditions.
