Poliosis circumscripta a genetic disorder.


: Poliosis is the decrease or absence of melanin (or color) in head hair, eyebrows, eyelashes, or any other hairy region. When it affects hair immediately above the forehead it is popularly known as white forelock. Single or less commonly, several white patches on the hair may cause this condition. Some mistake those white patches for simple marks of birth. In poliosis, the hair bulbs of infected hair follicles contain reduced or absent melanin; skin melanocytes are generally not infected. Poliosis occurs in various hereditary syndromes, including piebaldism, Waardenburg syndrome, type I neurofibromatosis, and tuberous sclerosis. It can also occur in conditions such as vitiligo, Vogt – Koyanagi – Harada disease, alopecia areata, sarcoidosis, neoplasms and other medications Share your comments on topic Email us: clingenom@peerreviewedjournal.org Submit your submission through direct online link: https://www.scitechnol.com/submission/ For more information visit our website: https://www.scitechnol.com/ We accept more than one paper for one author you can also go for membership.
