TLDR Green tea extract helps prevent cell death and supports cell survival in hair cells exposed to a chemotherapy drug.

In the 2018 study by Shin et al., the researchers found that Epigallocatechin-3-gallate (EGCG), a component of green tea extract, could promote cell survival and inhibit apoptosis in human dermal papilla (HDP) cells that were exposed to paclitaxel, a chemotherapy drug known to cause hair loss. EGCG's protective effect was dose-dependent, and fluorescence-activated cell sorting (FACS) analysis confirmed its anti-apoptotic properties. Additionally, microRNA (miRNA) microarray analysis revealed that EGCG altered the expression of 48 miRNAs in paclitaxel-treated HDP cells, which are involved in the regulation of genes associated with apoptosis and cell proliferation, and related to signaling pathways like MAPK and Wnt. The study did not specify the number of cells or participants involved.
