Head Lice at School — Everything Parents Need to Know
LICESPOT Guide · Updated May 2026 · 5 min read
Receiving a lice notification from your child's school is one of those moments that causes instant stress. But head lice at school is extremely common — it is not a sign of anything wrong with the school, your child, or your home. Here is everything you need to know to handle it calmly and effectively.
Why schools are a common lice environment
Head lice spread through direct head-to-head contact — and children have a lot of it. Playing together, hugging, reading from the same book, taking selfies, or simply sitting close during group activities are all opportunities for lice to transfer between children. Lice do not jump or fly — they can only crawl, so direct contact is required.
Sharing hats, scarves, hair accessories and brushes can also transfer lice, though this is a less common route than direct contact.
Key fact: Head lice have nothing to do with cleanliness. Clean hair is actually slightly easier for lice to move through than oily hair. Any child in regular contact with other children can get lice.
When is lice season at school?
Lice cases peak at two predictable points in the school year: the return to school in August–September, and the return after the Christmas/winter holiday break in January. These are the times when children from different households come back together after being apart, and any infestations that developed over the break get passed around.
However, lice can spread at any time during the school year whenever children are in close contact — which is always. Regular weekly checks during the school year are the best preventive measure.
Got a notification from school? Do this immediately
Check your child the same day
The sooner you identify an infestation, the easier it is to treat. Use the LICESPOT filter to scan quickly, then confirm with a fine-tooth lice comb on wet hair. Focus behind the ears and at the nape of the neck first.
Check all family members
If one child in the family has lice, siblings and adults who have had close contact should be checked too. Treat everyone confirmed at the same time.
Start treatment the same day if lice are found
Get a lice treatment from the pharmacy. Ask the pharmacist to recommend the right product for your child's age. Apply it correctly and note the date — you will need to repeat it in 7–10 days.
Notify the school even if you found lice
Even if you received the notification and then found lice on your own child, let the school know. This helps them track the situation and ensures the class is fully informed.
When can my child return to school?
In most cases, a child can return to school the day after treatment has been applied. Extended absence is not necessary or recommended. The main concern is active, untreated infestation — once treatment has started, the risk of spreading is significantly reduced.
Check your school's specific policy, as this can vary. But health authorities in most countries do not recommend keeping treated children home.
How to prevent reinfestation during the school year
Once you have dealt with a lice infestation, the goal is to prevent it from happening again. These practical steps reduce the risk significantly:
- Tie long hair back — braids and buns significantly reduce the surface area for lice to transfer onto
- No sharing — hats, scarves, hair ties, brushes and combs should not be shared
- Weekly comb-through — a quick 5-minute comb-through on wet hair once a week catches any new infestation before it becomes established
- Use LICESPOT regularly — a quick scan with the color filter takes under a minute and can catch lice early

Frequently asked questions
When is lice season at school?
Cases peak at the start of the school year in August–September and after winter holidays in January. But lice can spread at any time children are in close contact, which is the entire school year.
Should I send my child to school if they have lice?
Treat first, then return. Once treatment has been applied, your child can usually go back the next day. Extended absence is not necessary or recommended by health authorities.
How do schools handle head lice?
Schools typically send a confidential group notification encouraging all families to check their children. They do not identify which specific child had lice. Policies on exclusion vary, but most health authorities advise against keeping treated children home.
How can I protect my child from getting lice at school?
Tie long hair back, avoid sharing hats and hair accessories, and do a quick weekly comb-through at home. Regular checks catch infestations early before they spread further.
