Head Lice and Nits
Introduction to Head Lice and Nits
Head lice are tiny insects that infest the hair and scalp, feeding on blood several times a day. Nits are the eggs laid by adult female lice and attach to the hair shaft close to the scalp. They are a common problem, especially among school-aged children.
Understanding Head Lice
Head lice are six-legged insects that are about the size of a sesame seed. They are usually tan to grayish-white in color and move quickly in the hair. Adult lice can lay up to six eggs a day, leading to a rapid infestation if not treated promptly.
Symptoms of Head Lice
- Itching on the scalp
- Visible lice or nits in the hair
- Irritability and difficulty sleeping
Preventing and Treating Head Lice
To prevent head lice infestations, avoid sharing personal items like hats, combs, and headphones. Treatment typically involves using medicated shampoos or lotions that kill the lice and their eggs. It is important to thoroughly comb the hair with a fine-toothed nit comb to remove any remaining nits.
Tips for Treating Head Lice
- Follow the instructions carefully when using lice treatment products
- Wash bedding and clothing in hot water to kill any lice or nits
- Check all family members for lice and nits if one person is infested
