The infestation may spread to hair around the anus, abdomen, axillae, chest, upper arms, eyebrows, and eyelashes. [23] Rarely, facial hair (ie, beard, moustache, eyebrows, eyelashes) is a site of infestation. [23] Scalp involvement is rare and is usually confined to the marginal areas. In adults, eyelash involvement in the absence of genital involvement is rare. In prepubertal children, the eyebrows and eyelashes are the typical sites of infestation. Eyelash nits are a manifestation of pubic louse infestation, not head louse infestation.
