April 2026 in “Journal of Cosmetic Dermatology” This study found that exosomes derived from human umbilical cord mesenchymal stem cells helped preserve melanocyte function and mitigate stress-induced hair depigmentation in mice by activating the Nrf2-ARE antioxidant pathway under acute neurogenic oxidative stress.
July 2022 in “Journal of Investigative Dermatology” This study found that Substance P increased mitochondrial activity and biogenesis markers in cultured human scalp hair follicles, suggesting a novel link between stress-related neuropeptide signaling and hair follicle mitochondrial responses.
