This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

This study found that neurotrophins produced by balding dermal papilla cells inhibited both their proliferation and hair follicle growth in vitro, suggesting a potential role in androgenetic alopecia.

In this study, cyclosporine A stimulated hair growth in mouse vibrissae organ culture by promoting matrix cell proliferation and altering growth factor expression.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This review discusses the brain-skin connection, the skin's role in stress response, and highlights unmet challenges in understanding stress-induced skin inflammation but reports no new experimental findings.
