Notes:
(1) misdiagnosis of persistent infection: Some parents find the diagnosis of head lice to be traumatic and afterwards become hypervigilant, mistaking dandruff or other innocuous findings as evidence of persistent infection.
(2) reinfestation from another person: Everyone in the environment needs to be treated simultaneously to prevent retransmission.
(3) reinfestation from source in the environment: Caps and bed linen need to be carefully cleaned to remove eggs and lice.
(4) Some people coating the hair with baby oil, provided that the hair is not too long.
Purpose: To identify causes of apparent treatment failure for a patient with head lice.
