Encourage parents to send children with hair up
The single most helpful step is asking parents to send children with long hair in a bun or tight braid. If the hair is up and not touching, head lice cannot transfer.

Clear, practical education on handling head lice in a preschool setting.
Why this education matters
Why This Education Matters
Head lice is going to happen in a preschool setting. The goal is not to pretend it won’t — the goal is to handle it correctly so it does not turn into a larger problem.
Without accurate information, small cases can become super-spreader events. Once that happens, social media and parent conversations can quickly create unnecessary panic and a reputation problem for the school.
Head lice is actually simple to manage when you understand how it works. Most of the frustration comes from doing the wrong things and not knowing what is actually going on. This page is designed to give staff the clear facts so everyone responds the same calm, effective way.
Classroom myth
Head Lice Does Not Live in the Classroom
A common reaction is to clean cubbies, jackets, carpets, and shared spaces. Frankly, that is a waste of time.
Head lice cannot live off a person for long. They feed every three to four hours. When they feed, they secrete saliva that thins the blood so they can extract it from the scalp. Once they are away from a human head for more than about 12 hours, they become too dehydrated to secrete that saliva and can no longer feed.
Cleaning the classroom does not solve the problem. When you deal with head lice, the focus must stay on the child — someone, not somewhere.
How it spreads
How Head Lice Actually Spreads
Head lice spreads through direct head-to-head contact.
Young children naturally have very little personal space. During play, circle time, and group activities they are often close enough for hair to touch. That is the main reason head lice moves easily in a preschool classroom.
Sharing hats, coats, or hair items is possible but uncommon. The real driver is head-to-head contact.
01
Direct contact
Head-to-head contact is the main way lice moves from one child to another.
02
Close preschool play
Circle time and group activities naturally bring young children close together.
03
Shared items are uncommon
Hats, coats, and hair items can be involved, but they are not the main driver.
What staff can do
The Most Effective Things Staff Can Do
2
Gentle reminders during class
When you see children in close contact, a simple reminder helps.
“Make sure you have a little personal space. If your hair
doesn’t touch, you’re good.”
Simple habits
These two habits make a real difference.
How to check properly
How to Check Properly
Most visual checks miss lice and nits because they are dark and blend into the hair. Looking through the hair is not reliable.
Important
A proper comb-based check is the only accurate method.
Basic / Classroom Head-Check Demonstration
Use this same comb-based method for a regular staff check or a
full classroom check.
- Use a good metal lice comb.
- Work the key areas: temples, forehead hairline, nape of the neck, and crown.
- After every 4–5 swipes, wipe the comb on a white paper towel.
- Nits and lice are dark and will show up clearly. Dandruff and dry skin are white and will blend into the towel.
When a child needs to go home
When a Child Needs to Go Home
If live lice or nits are found:
1
Keep the conversation private and calm.
2
Contact the parent directly.
3
Explain that the child needs treatment and must be free of live lice and nits before returning.
The critical step most schools miss
The Return Check
This is the biggest problem we see.
Many schools look through the hair when a child returns after treatment and clear them. If the treatment did not fully kill the eggs and the nits were not completely removed, those eggs can still hatch. Two to three weeks later the child often has lice again. At that point the school and the family are left blaming the home or each other — when the real issue is that the child was never fully cleared.
Always perform a proper comb-based check before allowing a child back into the classroom.
A visual check is not enough.
Return-check demonstration
Check more thoroughly before the child returns.
This check is more thorough because the child has already been treated and is returning to the classroom.
If multiple cases appear
If Multiple Cases Appear (Classroom Check)
If several children in the same class are found with head lice, a full classroom check is the best way to stop further spread.
Use the same comb-based method. Work systematically so no child is missed, and keep the process calm and private.
