Head lice are tiny bugs that can live in the hair and on the head. Live lice are tan to grayish white. They're about the size of a sesame seed. It may be easiest to find them on the back of your child's neck at the hairline or behind the ears. When your child has lice, all people living in your home need to be carefully checked and then treated if they have it.
Lice eggs (nits) may be easier to see than live lice. They look like tiny yellow or white dots attached to the hair, close to the scalp. Nits can look like dandruff. But you can't pick them off with your fingernail or brush them away.
Lice aren't dangerous. They don't spread disease or have anything to do with how clean someone is. The lice may make your child's head itch. This is because of your child's body's reaction to the lice bites.
You can treat lice and their eggs with prescription or over-the-counter medicines. After treatment, your child's skin may itch for a week or more.
Head lice are most common in preschool and elementary school children. Children who have lice should be able to keep going to school. Experts recommend that children should not be kept from school because of lice or nits.
Head lice may cause an itchy feeling on the scalp. This is because of your body's reaction to the lice bites. But not everyone has itching, and not all itching means you have lice. Lice can be on the scalp for 4 to 6 weeks before itching starts.
There are several over-the-counter medicines that kill lice. Most of them are creams or shampoos that you put on the scalp. There are also prescription medicines. Each type of medicine is a little different, so it's important to follow the directions carefully. Your doctor or pharmacist can answer any questions you may have.
You can check for head lice at home. Use a fine-toothed comb. Part small sections of hair in a place with good light. Using a magnifying glass can help. You can also check with a doctor, who will ask about symptoms and check the scalp and hair for lice and nits.
Try an over-the-counter medicine to kill lice. Your doctor or pharmacist can suggest a medicine. Follow the directions carefully. Some medicines require a second treatment. If you find live lice after treatment, check with your doctor. You may need a different treatment. Try an over-the-counter anti-itch cream to calm itching if needed.
Adult head lice (or "louse" for just one) are approximately the size of a sesame seed and can vary in color from white to brown to dark gray.
Louse eggs (nits) are much smaller and look like light gray or brown ovals that are glued to individual hair shafts.
Head lice spread from one person to another through close bodily contact. Sometimes they spread when people share clothing or personal items such as hats or hairbrushes.
Head lice are tiny insects that live close to the scalp, where they lay and attach their eggs (nits). Lice can't survive unless they are close to the scalp.
Head lice are most common in children. They can spread anytime a child's head comes into contact with the head or hair of someone who has lice. Lice can't fly or jump.
Head lice aren't dangerous. They don't spread disease or have anything to do with how clean someone is.
