This lesson introduces head lice, tiny insects that live in hair and cause itching but do not make people sick. It explains how lice are transmitted through shared items, their life cycle, and how to identify and treat an infestation using special shampoos and cleaning methods. The key takeaway is that while having lice can be uncomfortable, it is manageable and not a cause for alarm.

What Are Head Lice?

Hey there! Have you ever heard of head lice? They’re tiny bugs that like to live in people’s hair, and they can make your head really itchy. But don’t worry, head lice can’t make you sick!

How Do You Get Head Lice?

Head lice don’t jump from person to person. The only way you might get them is by sharing things like hats, hairbrushes, or pillows with someone who has lice. Anyone can get lice, and it doesn’t mean they’re dirty. In fact, lice prefer clean hair because it’s easier for them to hold onto!

What Do Lice Do?

Lice are like tiny mosquitoes because they bite your scalp to feed on your blood. They have six legs with claws to grip your hair. Lice are about the size of a strawberry seed. When a louse gets into your hair, it lays eggs called nits, which stick to your hair like glue. After about a week, these eggs hatch into young lice called nymphs, and in another week or so, they become adult lice.

How Do You Know If You Have Lice?

If your head is itchy, it’s a good idea to check for lice. Sometimes people mistake dandruff or dirt for lice, so it’s best to ask an expert like a nurse to look at your scalp. They might use a special comb or a blacklight to find the lice.

How to Get Rid of Lice

If you have lice, you can use a special shampoo to get rid of them. This shampoo often contains chemicals from the chrysanthemum flower, which kill lice. You might need to use the shampoo again after a week to make sure all the lice and their eggs are gone. You should also wash your bed sheets and clothes in hot water and put your favorite stuffed animals in the dryer to make sure they don’t have lice.

Don’t Worry!

Having head lice isn’t fun, but it’s nothing to worry about. It’s important to tell an adult if your head is itchy so they can help you get rid of the lice. Remember, lice are pretty harmless, and there are easy ways to get rid of them!

  • Have you ever had an itchy head before? What did you do to make it feel better?
  • Why do you think it’s important not to share things like hats or hairbrushes with others? Can you think of other things we should be careful about sharing?
  • If you found out a friend had lice, how would you help them feel better and not embarrassed?
  1. Observation Adventure: Take a magnifying glass and explore different textures in your environment. Look at your hair, a piece of fabric, or a leaf. Imagine how tiny lice might move around and hold onto these surfaces. Discuss with a friend or family member how lice use their claws to grip hair.

  2. Role-Playing Game: Pretend to be a louse and a strand of hair. One person can be the louse, using their fingers to mimic the claws, and the other can be the hair, holding still. Try to “hold on” as the louse and see how it feels to move around. Switch roles and talk about what you learned from each perspective.

  3. Creative Drawing: Draw a picture of a louse and its life cycle. Include the eggs (nits), nymphs, and adult lice. Use different colors to show each stage and label them. Share your drawing with a classmate and explain what happens at each stage of the life cycle.
