May 2022 in “International journal of molecular sciences” This study found that heat-killed Enterococcus faecalis EF-2001 promoted hair regrowth in mice, likely by increasing the expression of growth factors and marker genes.
April 2014 in “The FASEB Journal” This study found that Geranium Sibiricum L extract may promote hair growth by increasing cell proliferation and migration while modulating cytokine expression in human dermal papilla cells under stress conditions.
June 2026 in “Applied Biological Chemistry” This study found that the M5 isolation method for human dermal papilla cells significantly improved attachment efficiency, proliferative capacity, and trichogenic potential, providing an optimized strategy for scalable manufacturing in hair regeneration therapies for conditions like alopecia.
January 2026 in “Nature Communications” This study presented a new wearable textile-based device with near-infrared OLEDs that significantly reduced cell aging markers and improved cell migration in vitro, suggesting it as a promising, non-invasive phototherapy option for hair follicle treatment and hair-loss management.
