Head Lice in Children: How to Recognize and Remove Them
Head lice are fairly common in preschools and schools and are not a sign of poor hygiene at home. Learn how to recognize and treat them and how to inform your childâs group sensitively.

What Is Head Lice and Why Does It Spread Mainly in Groups?
Head lice is an infestation of the scalp by head lice. It is an unpleasant but common situation that families with children often encounter in preschools, schools, camps, or clubs. Lice spread most easily through close head-to-head contact, for example while playing together, reading, hugging, or leaning over the same toy.
It is important to say this clearly and without shame: head lice are not a sign of poor hygiene or âdirtyâ hair. They can attach to both clean and unwashed hair. Neither the child nor the parent is to blame, and a calm, matter-of-fact approach helps resolve the situation more quickly.
Lice cannot fly or jump. Transmission through hats, combs, hair ties, or bedding is possible but less typical than direct hair-to-hair contact. That is why early detection and checking all close contacts are most important.

If lice appear, discreetly inform the school, preschool, or other facility the child attends. Staff can alert other families without naming the child, allowing parents to check their childrenâs hair. Cooperation across the whole group is what helps reduce the risk of repeated spread.
Signs: What Head Lice and Nits May Look Like
A common sign is an itchy scalp, especially at the nape of the neck and behind the ears. The child may scratch, become irritable, or sleep poorly. However, itching may not appear immediately and does not by itself mean that the child has lice â dry skin, eczema, or hair products can also irritate the scalp.
When checking, look primarily for live lice and nits. Lice are tiny, mobile, grayish-beige to darker in color. Nits are eggs firmly attached to the hair, usually close to the scalp, especially behind the ears and at the nape of the neck. Unlike dandruff, they cannot be easily blown away or slid off the hair with your fingers.
- Check the hair in good daylight or under a strong lamp.
- It helps to divide the hair into smaller sections and examine them gradually from the roots.
- A fine-toothed metal comb is an effective tool for removing lice.
- Check everyone in the household and anyone who has been in close contact with the child.
If you are unsure what you are seeing in the hair, ask a pharmacist or pediatrician for advice. Also contact the pediatrician if the child has severely irritated skin, sores, or scabs from scratching, or if the problem keeps returning.
How to Remove Lice Step by Step
If you find live lice, start taking action promptly, but there is no need to panic. Pharmacies offer products intended to treat head lice, such as solutions, sprays, or shampoos. Choose only a product suitable for the childâs age and always follow the manufacturerâs instructions precisely â including the application method, treatment time, and whether and when to repeat the treatment.
- Treat the childâs hair with the product according to the instructions. Do not use more product or leave it on longer in the hope of achieving a better result.
- Comb through the hair with a fine-toothed comb. Work in small sections, from the roots to the ends. Wipe the comb on a paper towel or rinse it after each pass.
- Remove the nits mechanically. Combing and manually removing nits is an important part of care, even when you use a pharmacy product.
- Check close contacts. Treatment is needed for anyone in whom you find live lice. Preventively treating everyone without finding lice may not be appropriate â follow the advice of a pharmacist or pediatrician.
- Repeat the checks. Continue carefully examining and combing the hair over the following days. If the instructions recommend a second application, follow the specified interval.
Avoid homemade âguaranteedâ methods such as harsh chemicals, kerosene, highly concentrated essential oils, or other products not intended for a childâs scalp. They may irritate the skin or be dangerous.

What to Do at Home and What Is Not Necessary
Lice do not survive for long away from the human head, so there is no need for a deep clean or insecticide sprays in the home. Transmission through objects is less common than direct head-to-head contact. Focus only on items that have been in immediate contact with the childâs head during the past few days.
- Wash bedding, pajamas, hats, and towels at 60°C if the material allows.
- Clean combs, brushes, hair clips, and hair ties thoroughly; combs and brushes can be washed with hot water and soap.
- Extensive vacuuming, boiling items, or specially disinfecting the entire home is not necessary.
Much more important than extensive household disinfection is thorough combing, checking the hair, and informing the childâs group. Reassure your child that they have done nothing wrong. Avoid words that could make them feel ashamed.
Prevention and Returning to Preschool or School
It is not possible to completely prevent head lice in a group of children, but regular hair checks help detect the problem early. After receiving a notice from the preschool or school, check your childâs head as soon as possible, even if they are not scratching.
- Teach your child not to share combs, brushes, hats, helmets, hair clips, or hair ties.
- For longer hair, tying it into a ponytail or braid may help.
- While lice are present in the group, check the hair more often, especially at the nape of the neck and behind the ears.
- Do not rely solely on repellent sprays or shampoos for prevention. They do not replace regular checks and careful treatment of a confirmed infestation.
The rules for returning to the facility may vary. Ask the class teacher or the preschool or school administration directly. In general, it is important that the child has been treated and that the parent continues checking the hair according to the instructions for the chosen product.
Head lice can catch parents off guard, but they can be managed with a calm approach. Early checking, correct use of a suitable product, thorough combing, and sensitive communication with the group are the most important steps.
