First Aid: Head Lice

Print this page Bookmark and Share

First Aid

A head louse is a tiny, wingless insect that can attach to a person's hair, where it feeds on tiny amounts of blood drawn from the scalp. Lice, while annoying, aren't dangerous and they don't spread disease.

Signs and Symptoms

  • severe itching of the scalp
  • nits (tiny oval specks of grey or yellow-white on the hair shaft)
  • lice (reddish brown tiny insects on the hair shaft)
  • small red bumps on the scalp
  • a rash on the scalp, with crusting and oozing (if severe)
  • swollen lymph glands in the neck

What to Do

A doctor will recommend a medicated rinse or lotion to kill the lice. It's important to follow the directions for these products exactly because applying too much or too often can be harmful.

Here are some ways to get rid of lice and their eggs around the house:

  • Check everyone in the house for lice and seek treatment if necessary.
  • Wash all bed linens and clothing in very hot water, then put them in the hot cycle of the dryer for at least 20 minutes.
  • Dry clean any clothing, bed linens, and stuffed animals that aren't machine washable.
  • Vacuum carpets and any cloth-covered furniture in your home or car.
  • Discard hair-care items or soak them in rubbing alcohol for 1 hour, then wash them in hot soapy water.
  • While not necessary, you can remove nits from hair with a fine-tooth comb.

Seek Medical Care

If Your Child:

  • shows any signs of having lice
  • is constantly scratching or complains of itches that don't go away
  • has scratched the scalp to the point of redness, swelling, or visible pus

Think Prevention!

You can help protect your kids from head lice by teaching them to:

  • avoid head-to-head contact with other children
  • not share combs, brushes, hair ties, hats, etc.
  • not lie on bedding, pillows, and carpets that have recently been used by someone with lice
