Lice live in the hair shaft. They produce eggs that are attached to the hair shaft by a glue-like substance made by female louse secretions. These eggs hatch after a week. Lice are small, six-legged insects that are grayish white or red in color. During the adult stage, they can lay up to 10 eggs a day.
Adult head lice are about two to three millimeters long. They have flat bodies, six legs, and can attach to human hair. The nymphs are similar to the adult head lice but are much smaller. Adult lice lay their eggs near the scalp or on the nape of the neck. They stick to human hair at a distance of one centimeter or less.
Treatment options for head lice include topical creams and medicines. It is important to follow the instructions for these medications. You can also visit a doctor for proper treatment. Usually, the treatment will kill adult lice and their eggs. However, the treatment must be repeated until the infestation has been eliminated completely.
Head lice can cause sores that are not visible to the naked eye. However, you can still check your hair for nits and larvae using a magnifying glass. It may take 4-6 weeks before you see signs of an infestation, and some people may not exhibit any symptoms at all. During this time, a tickling or itching sensation will probably occur. Some people also experience difficulty sleeping.
