June 2025 in “Universal library of medical and health sciences.” This study reviewed literature on hair growth and found that external factors like pollution, stress, and nutrition can adversely affect hair, concluding that a multifactorial approach and personalized nutrition monitoring are essential for effective hair loss therapy.
August 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This review suggests that hair loss involves a complex interplay of androgen signaling with various regenerative and inflammatory pathways, challenging the view of dihydrotestosterone as the sole cause.
August 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This narrative literature review by LUSTRAO examines the complex biological mechanisms influencing hair growth and loss, highlighting that androgen signalling, while significant, works within a network involving regenerative, inflammatory, and vascular processes, without establishing it as the sole explanation for conditions like androgenetic alopecia.
March 2018 in “Digital Access to Scholarship at Harvard (DASH) (Harvard University)” In this study, chronic stress signals were found to delay hair follicle stem cell activation and negatively impact their niche components in rodents.
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.
