When Does Head Lice Itch the Most?

Itching is the main symptom of head lice, but it is not always immediately apparent. It can start weeks or months after the first lice bite. The itchiness can also be an allergic reaction to the lice’s saliva. The itchiness may be accompanied by sores on the head, which can become infected if not treated in time.

Lice are parasitic insects that feed on human blood. When they bite the scalp, their saliva irritates the skin and causes an itchy red bump. Even if the lice are eliminated, the itch might continue for days. You can temporarily relieve the itching by applying an ice pack or a cold compress.

Although head lice can be a discomforting condition, it is not serious. It is spread by direct head-to-head contact or by sharing clothing and belongings with an infested person. The only way to avoid contracting the disease is to avoid contact with infested individuals, and to treat nits as soon as you notice an infestation.

Lice are tiny, six-legged insects that live on the head. They tend to stay near the scalp and behind the ears. However, they can also infect the eyelashes and eyebrows.
