Plica neuropathica (polonica) presents as a compact mass of scalp hair with irregular twists and irreversibly entangled plaits which are firm to hard impenetrable mass of keratin cemented together with dirt and exudates.

 

Treatment of plica neuropathica involves cutting the matted hair. In early cases, manual separation using organic solvents can be tried.

 

Prevention includes hair care measures like regular cleaning of hair with mild cleansers or shampoos, gentle oiling and combing to avoid entangling and regular hair trimming. Hair piling over vertex while washing and backcombing should be avoided.
