The head louse bites the host’s scalp, injects saliva into the bite, and then sucks its victim’s blood.

The itch on the scalp is caused both by the louse’s bite and the injected saliva.

Symptoms of head lice infestation

Symptoms of head lice infestation include:

  • An itchy scalp or itching at the back of the neck or behind the ears
  • Head lice eggs (nits) that look like dandruff on hair shafts and clothes
  • A crawling sensation on the scalp
  • Conjunctivitis
  • Blepharitis

The life cycle of the head louse
