It's a myth that African American children don't get head lice. According to Andrea Beth Trowers, MD, of the University of Miami, African American children are much less likely to have head lice (medically called pediculosis capitis) than white or Hispanic children.
Large American studies have found that up to 25% of white children have had head lice, compared to less than 1% of African American children. However, similar studies in Brazil and Nigeria found higher rates of infestation in black children.
There are a number of possible explanations for the low infestation rate. One factor is the difference in hair characteristics between white and African American children. Head lice have problems latching on to curly and kinky hair. In addition, African American hair is more elliptical than white children's hair and head lice find it difficult to hold onto elliptical hair. In Africa, where the percentage of children with head lice is higher, lice have adapted their claws to better grasp elliptical hair.
Another explanation is that African Americans are more likely to use Vaseline, pomades, and hair gels. These products make the hair less hospitable to head lice.
Head lice are making a comeback. They are also becoming resistant to many of the over-the-counter products. Although less likely to occur in African American children, it's still possible. All children in high risk areas should be regularly checked for lice and, if found, treated appropriately.
