Head lice are a common and frustrating problem, especially among children. These tiny, wingless insects live on the human scalp, where they feed on blood and cause intense itching, irritation, and discomfort.

While not dangerous, head lice are highly contagious and can quickly spread through direct contact or by sharing personal items like combs, hats, or towels. Their presence can be hard to detect, but their eggs, known as nits, cling tightly to hair near the scalp. Understanding what head lice are, how they spread, and how to treat and prevent them is essential for effective management and peace of mind

What are head lice and what do they look like

Head lice are tiny, wingless insects that live on the human scalp, feeding on blood.

They are highly contagious and can spread through direct head-to-head contact, sharing personal items, or lying on contaminated surfaces.

Head lice

Adult lice are tiny, gray or tan creatures with three pairs of claw-like legs, about the size of a sesame seed or smaller. Due to their quick movement, it's often easier to spot their eggs rather than the lice themselves. These eggs, also known as nits, are small, white, yellowish, tan, or brown specks that cling tightly to hair shafts close to the scalp.

They can be mistaken for dandruff, but unlike flakes, they don't come off easily.

To remove them, use a nit comb and conditioner to gently pull them out

The most common symptoms of head lice include:

Intense itching: Caused by the lice biting and feeding on the scalp.
