"The Polish plait usually results from deficient hair care. Uncombed hair becomes irreversibly entangled, forming a matted, malodorous and encrusted or sticky moist mass. It may be caused by or accompanied with lice infestation (pediculosis) and lead to inflammation of the scalp. The Polish plait is typically a (sometimes large) head of hair, made of a hard impenetrable mass of keratin fibers permanently cemented together with dried pus, blood, old lice egg-casings and dirt. The disease may be easily prevented by standard hygienic practices, such as washing and combing of the hair. Treatment involves cutting the affected hair."
