Answer

Louse infestation affects all races and ethnic groups. However, in North America, the reported incidence of head louse infestation is lower in African Americans than in any other racial group, probably in part because of the use of pomades and in part because the claw size of the head louse is more adapted to the round shape of the hair shaft found in white persons and Asian persons. [24] However, blacks may experience P pubis scalp infestation.
