Lice basics
Head lice (Pediculus humanus capitis) are tiny parasites that live on human scalps, feeding on blood.
They are about 2-3 millimeters long—roughly the size of a sesame seed—and can be gray-tan in color.
Unlike common misconceptions, head lice do not spread diseases and are not a sign of poor hygiene.
They spread primarily through direct head-to-head contact, such as during close play or naps in school settings.
Lice cannot jump or fly, and they cannot survive more than 48 hours away from a human scalp.
Female lice lay eggs near the scalp, attaching them firmly to hair shafts with a glue-like substance.
These eggs take 8 to 9 days to hatch, and the newly hatched lice mature in about 9 to 12 days.
Lice have been companions to humans since ancient times, and they can infest all hair types, regardless of texture or cleanliness.
