The document investigates the neurological and neuroendocrine mechanisms behind segmental vitiligo and its association with white hair, emphasizing the role of melanocytes and neuropeptides like NPY. It highlights that stress and sympathetic nerve dysfunction contribute to melanocyte destruction, leading to depigmentation and hair whitening. Elevated levels of norepinephrine and NPY are observed in vitiligo patients, linking them to oxidative stress and immune responses. The study suggests that managing stress and sympathetic nerve activity could be therapeutic targets. Early intervention, including medical, phototherapy, and surgical treatments, along with psychological management, is crucial for effective treatment and repigmentation efforts.
