چکیده :

Background: Occupational stress may influence hair-follicle cycling and may be associated with forms of non-androgenetic hair loss. Healthcare workers are exposed to occupational stressors, including prolonged working hours and heavy workload. This review examines potential mechanisms linking occupational stress with hair-follicle dysfunction and clinical approaches. Method: A narrative review was conducted using PubMed/MEDLINE, Scopus, and Google Scholar up to June 2026, without language restrictions. Searches combined terms related to hair growth, hair follicle, hair loss, alopecia, and occupational or job stress. Literature on biological mechanisms, occupational factors, clinical manifestations, prevention, and management was synthesized narratively. Finding: The recent studies have shown that the psychological stress could affect the functioning of hair follicles through allostatic load and stress reaction, alteration of follicular immunity communication and regulation of follicular stem cells. The experimental data confirm the theory of the adverse influence of psychological stress on hair growth due to the involvement of neuroendocrine mechanisms. There is a number of clinical evidence about the possible connection between hair shedding, including telogen effluvium, and psychological stress. The working hours and workload are the occupational risk factors for stress; the wearing of tight protective headgear for a long time is the risk factor for mechanical stress or traction. Conclusion: Occupationally associated hair loss is likely multifactorial. Potential contributors include neuroendocrine and immune alterations, sleep disturbance, nutritional factors, and mechanical occupational exposures. Appropriate dermatologic assessment and evidence-based stress management may help address stress-associated hair loss. However, direct evidence linking occupational stress to alopecia remains limited.
