Head Lice
What are head lice?
Head lice live only on human beings. They can be spread
quickly by using the hat, comb, or brush of an infected
person. The nits (eggs) normally hatch into lice within
1 week. Your child probably has lice if:
- The nits (white eggs) are firmly attached to hairs.
Unlike dandruff, nits can't be shaken off.
- There are gray bugs (lice) in the hair about 1/16 inch
long. They move quickly and are difficult to see.
- Your child's scalp itches and has a rash.
How can I take care of my child?
- Anti-lice shampoo or rinse. Your child's anti-lice
shampoo is ______________________. Follow the
directions. Most products must be used on dry hair.
Pour about 2 ounces of the anti-lice shampoo into the
hair. Add a little warm water to work up a lather.
Scrub the hair and scalp for 10 minutes. Rinse the hair
thoroughly. The shampoo kills both the lice and the
nits. Repeat the shampoo in 1 week.
- Removing nits. To make sure the nits are dead, wait at
least 8 hours after using the shampoo before removing
them. Remove the nits by combing the hair with a
fine-tooth comb or pulling them out one by one.
- Cleaning the house. Lice can't live more than 24 hours
off the human body. Nits can live for 2 weeks.
Vacuum your child's room. Soak combs and brushes 1
hour in a solution made from the anti-lice shampoo.
Wash your child's sheets and pillowcases in hot water.
Put things that can't be washed (hats or coats) in
plastic bags for 2 weeks (until the nits are dead).
- Contagiousness. Check the heads of everyone living in
your home. Treat anyone who has scalp rashes, sores, or
itching. Also treat anyone who sleeps in the same bed
with your child. Your child can return to school after
the first treatment with the shampoo.
Call your child's doctor during office hours if:
- The rash and itching are not gone 1 week after treatment.
- The sores start to spread or look infected.
- The lice and nits return.
- You have other questions or concerns.
