    GlossaryFocal Atrichia

    localized hairless patch on scalp or body

    Focal Atrichia refers to a localized area on the scalp or body where hair is completely absent. This condition can be congenital or acquired and is often due to genetic factors, autoimmune disorders, or localized trauma to the hair follicles. It is different from more widespread hair loss conditions like alopecia areata, as it is confined to a specific spot.
