April 2026 in “Microorganisms” The study explored the anti-hair loss potential of Staphylococcus capitis KMH304 ferment filtrate (SCFF) derived from the scalps of 20 healthy Korean participants. SCFF was tested on human hair-follicle dermal papilla cells and keratinocyte cells, showing enhanced cell viability, proliferation, and modulation of hair growth markers while reducing androgenetic alopecia-inducing markers. It also demonstrated anti-aging effects, improved scalp barrier function, and exhibited antioxidant properties. Despite the small participant pool, the findings suggest SCFF's potential as a novel cosmetic ingredient for promoting hair growth and scalp health by modulating biological pathways associated with hair loss.
