Has your child ever come home from school or daycare with head lice?

What was fairly rare a generation ago is now more common: Lots of kids are getting lice from their friends.

However, head lice aren’t the result of poor hygiene. Kids get them mainly by touching heads as they play or talk. The lice crawl from the head of one child to another.

According to the CDC, six to 12 million cases of head lice occur each year in the United States among children three to 11.

Prevention Tips

Head lice are tiny insects that attach themselves to the scalp, where they feed by sucking blood. They are grayish-white or tan and no bigger than a sesame seed.

Luckily, there are steps you can take to help keep them away from children. Carilion Children's pediatricians recommend the following:

  • Teach your child not to share hats or anything that comes in contact with the hair, including combs, hair ties, scarves, jackets or helmets
  • Ask her (or him) to avoid head-to-head contact with other children, whether they’re playing, participating in sports or at a slumber party
  • Tell your child not to use shared spaces where students hang their hats and clothes
  • Clean items that have touched the head of someone with lice in the previous 48 hours by machine-washing them with hot water (130°F) and drying them on high heat
  • Don’t let your child lie on couches, carpets or beds that have recently been used by someone with lice
  • Vacuum your furniture and floor if someone with lice has been in your home; they won’t live more than two days without a host
  • To disinfect a comb or brush used by someone with lice, soak it for five to 10 minutes in water that’s at least 130°F
  • For added protection, tie back long hair before sending kids out to play or to school  

What To Look for

If, in spite of all your efforts, you think your child has lice, what you should do?

  • Get a magnifying glass and stand your child in bright light
  • Part the child’s hair in various spots and check the entire scalp
  • Look for dandruff; lice can move quickly and be hard to see, so it may be easier to spot the eggs, or nits, which lay in the hair resembling dandruff
  • If you think you see a nit, lift a strand of hair and run your fingernail across the scalp. Dandruff will flake off, while nits will stick to the hair.

Treatment Options

If treatment for head lice is necessary, there are over-the-counter and prescription drugs available. But many are not meant for kids younger than two, so make sure you read the label before using one on your child.

Some over-the-counter products may also be flammable or irritating to the skin or lungs.

A good alternative is to consult your pediatrician, who may want to prescribe one of several FDA-approved drugs for head lice.

During and after treatment, keep tabs on the rest of your family. Check everyone after a week to be sure no one else has gotten lice.

And if it’s any consolation: your pets can’t contract lice. They only feed on humans.

Just think of it as a rite of passage as a parent and remember that you’re not alone.

Every other mom and dad potentially has to deal with this too!
