What Causes Head Lice?
Head lice are a common and bothersome problem, especially among children. These tiny, blood-sucking parasites can cause itching and irritation by attaching themselves to the scalp. In this article, you will find detailed information on what head lice are, what causes head lice, how they spread, and how to effectively get rid of them.
What Are Head Lice?
Head lice (Pediculus humanus capitis) are small, blood-feeding parasites that live on the human scalp. They are usually around 2–4 mm in size, making them difficult to see with the naked eye, but they can be detected upon closer inspection. Head lice are typically grayish-white and leave eggs (nits) on the hair strands throughout their life cycle. These nits stick tightly to the hair and are often found in areas like behind the ears or at the nape of the neck.
Lice only live on humans and do not spread from animals. Therefore, your pets cannot transmit lice to you.
What Causes Head Lice?
Many people mistakenly believe poor hygiene is what causes head lice, but that is not true. Lice can infest both clean and dirty hair. The real cause is close contact with someone who already has lice. This is especially common among children in schools or daycare centers.

- Head-to-head: interaction with an infected person.
