A hair follicle white plug in hair morgellons disease is a small, white, or off-white substance or material found embedded in or protruding from a hair follicle opening on the scalp. These plugs or fibers can vary in size and shape but are often described as thread-like or filamentous.
The presence of hair follicle white plugs is associated with the Morgellons disease, a controversial condition characterized by a range of symptoms, including skin lesions, crawling or stinging sensations, and fatigue. While the exact nature and cause of Morgellons disease are still debated, some research suggests a possible link to abnormal keratin production or infection.
