February 2026 in “Food Research International” Lactiplantibacillus plantarum ZJUIDS51 can help regrow hair and improve scalp health in androgenic alopecia.
March 2025 in “Research Square (Research Square)” This study explored the potential of the lysate and lipoteichoic acid from Lactiplantibacillus plantarum</i> APsulloc 331261 to improve scalp seborrheic dermatitis by modulating inflammatory and lipogenesis pathways in vitro, suggesting potential as a natural treatment option.
May 2024 in “Journal of Agricultural and Food Chemistry” In a study using mice, researchers observed that Cacumen platycladi fermented with Lactiplantibacillus plantarum CCFM1348—both as postbiotics and synbiotics—promoted hair growth, potentially by engaging the Wnt/β-catenin signaling pathway and enhancing growth factor expression.
In this study, researchers found that while applying a lotion containing Lactiplantibacillus plantarum subsp. plantarum N793 did not improve hair density overall compared to placebo, it was effective in improving hair density among individuals with relatively mild hair thinning.
November 2022 in “Nihon Nyuusankin Gakkaishi/Nihon Nyūsankin Gakkaishi” In a non-blinded study with 12 Japanese participants, applying a lotion containing Lactiplantibacillus plantarum N793 to the scalp for 24 weeks significantly increased hair density and reduced hair loss, with participants reporting improvements in hair thickness and volume, and the treatment deemed safe.
