What do head lice look like? 

Head lice are tiny insects that live on the scalp and feed on human blood. They are usually light brown or grayish-white in color, making them difficult to spot in dark hair. Here are some key characteristics of head lice:


  • Adult lice are very small, typically about the size of a sesame seed, and are difficult to see with the naked eye.

  • They have a flat and elongated body, which helps them move easily through hair. 


  • Lice can vary in colour, but they often blend in with the colour of the hair they are in. This makes them hard to spot, especially in dark hair.

  • Lice lay tiny eggs called nits, which are oval and about the size of a pinhead. Nits are often attached to the hair shaft close to the scalp and can be mistaken for dandruff or hair debris. However, unlike dandruff, nits are difficult to remove because they are glued to the hair.


  • Lice can move quickly and are agile, making them challenging to catch.
