Lice are small parasites that live on the human scalp and feed on blood. They lay eggs called nits, which are often mistaken for dandruff. To eliminate an infestation, both lice and nits must be killed or removed. Over-the-counter shampoos or specially designed combs can be used. Lice infestations are not a sign of poor hygiene and can be transmitted through contact with an infected person or object. Close contacts should be monitored.
Nits are the eggs of lice, parasites that live on the human scalp and feed on the blood of their host. Usually, nits are found attached to the hair shafts of their host. To eliminate a lice infestation, both the lice and the nits must be killed or otherwise removed from their host’s scalp.
Lice are parasitic insects that live on the human scalp and survive by feeding on the blood of their host. They are usually no larger than a sesame seed and therefore can be difficult to see. Many people only realize they have lice when the scalp begins to itch, a reaction to the saliva deposits left by the lice when they draw blood. Head lice are transmitted from person to person when an infected person’s head comes into contact with the head of an uninfected person, or when an uninfected person’s head comes into contact with an object that has touched the infected person’s head. like a hat or headphones.
Once the lice have infested their host’s scalp, they deposit their eggs, known as nits, on his or her hair. The nits are usually white or yellow in color and are extremely small. Many people mistake these eggs for flakes of dandruff and therefore cannot get rid of them. However, as long as they can hatch, the eggs will develop into adult lice which feed on their host and then lay their own eggs, a cycle which can continue indefinitely.
To eliminate a lice infestation, both the lice and the nits must be killed or otherwise removed from their host’s scalp. This can often be achieved by using over-the-counter shampoos designed to kill lice and their eggs. If an over-the-counter shampoo is unsuccessful in ending an infestation, a doctor may recommend a prescription shampoo treatment. Those who prefer not to apply chemical treatments to the scalp may want to try using a comb that has been specially designed to remove head lice and their nits. This treatment may need to be repeated for several days before all the lice and eggs are removed.
Contrary to what some people believe, a lice infestation is not an indication of poor personal hygiene. Anyone who comes into contact with head lice can become infested, and normal hair care procedures will not prevent or eliminate infestations. Therefore it is important to monitor the scalp of those who are in close contact with an infected person, such as family members and classmates.
