The Intersection of Sleep and Hair Loss: A Systematic Review

This systematic review highlights the potential link between sleep disturbances and hair loss, suggesting a bidirectional relationship where poor sleep quality may contribute to hair loss and vice versa. While most evidence is observational, both mechanistic and psychosocial data support this connection. The review recommends incorporating sleep assessments into hair loss treatment and considering sleep-targeted interventions to enhance disease management and patient well-being. However, further longitudinal and mechanistic studies are necessary to establish causality and identify specific therapeutic targets.
