It’s a good thing you’re reading this article, though, because we’ll tell you all about the causes, symptoms and treatments for head lice. So sit back, relax and enjoy the read!
What are Head Lice?
Head lice, scientifically known as Pediculus humanus capitis, are an invasion of the head that can spread at the snap of a finger and multiply even quicker. It’s very easy to infect those around you if you have it. Humans are the only species that get head lice, although other primates have similar lice which invade them. With the exception of extreme scratching, the lice don’t cause a lot of harm. Small anthropods, the lice live off the host’s blood by attaching themselves to the scalp and sucking off some of the rich sources of blood close the skin.
A louse injects saliva into the host while it feeds itself to prevent any blood clotting. This can result in an allergic reaction or itching sensation, and scratching that itch can lead to bacterial infection. However, lice don’t really transmit any diseases.
Because lice are so common, there are many treatments available around the world, but each culture tends to have their own answer.
Causes of Head Lice
An infestation of head lice may result from the direct transfer of the lice from an infested person. Lice cannot fly or jump because they do not have wings or long legs, but they can be transmitted through personal items like hats, clothing, towels, headphones, headbands, brushes and other things that may touch your hair.
Having lice isn’t really the result of poor hygiene or dirty hair, and it can happen to people with any length of hair. Lice also can’t be passed via animals.
Symptoms of Head Lice
An itchy scalp is the most common sign of lice. This is caused by an allergic reaction to the lice’s saliva, but people may also just be extremely sensitive to the biting itself. On the other hand, people can also build up a tolerance to the saliva and not get any itchiness if they get infested again.
Other symptoms of head lice include:
- Pink eye
- Swollen glands, or lymph nodes
- Sores that appear on the head because of scratching
- Difficulty sleeping and irritability
- Sensation of something moving in the hair or tickling the head
