If you have just spotted your child scratching their head and found a tiny crawling insect, take a deep breath. Head lice (sir ki joon) are one of the most common things a school-going child will pick up — and finding them says nothing about how clean your home is or how well you care for your child. They are annoying and itchy, but they are not dangerous. This guide walks you through how to recognise lice, how to clear them properly, and how to keep them from coming back.
Quick Answer
Head lice are extremely common in school-age children and have nothing to do with dirtiness — they affect clean and unclean hair alike. They spread mainly by direct head-to-head contact (and sometimes through shared combs, hats or pillows). The most reliable home treatment is wet combing with a fine-tooth lice comb (kanghi), repeated every few days for about two weeks; medicated anti-lice lotions or shampoos are also available, but must be used strictly as per the instructions and the right age. Prevent spread by avoiding head-to-head contact, not sharing combs or hats, and tying long hair back. See a doctor if the scalp looks infected, treatment is not working, or your child is very young.
What Head Lice Are and How Kids Get Them
Head lice are tiny wingless insects, about the size of a sesame seed, that live close to the scalp and feed on small amounts of blood. They cannot fly or jump. They spread almost entirely through direct head-to-head contact — exactly the kind of close play, hugging and head-touching that happens constantly among children at school, at home and at parties.
This is why lice are so common in school-age children, especially those with long hair. It is worth repeating, because so many parents feel embarrassed: lice are not a sign of poor hygiene. They are happy in any hair, clean or not. They also do not spread any disease — the main problem they cause is an itchy scalp, and the scratching that follows.
How to Spot Them
The signs are usually:
- Itching, especially behind the ears and at the nape of the neck — these are the warm spots lice love. The itch can take a little while to start, so a child may have lice before scratching begins.
- Nits (eggs): tiny pale or whitish specks firmly stuck to the hair shaft near the scalp. A simple way to tell nits from dandruff or dust: dandruff flakes brush or shake off easily, while nits stay stuck and have to be slid off the strand.
- Moving lice: sometimes you can see the lice themselves moving on the scalp, particularly when the hair is wet and you part it under good light.
If you are unsure, wet the hair, part it in sections under a bright light, and look closely near the scalp.
How to Treat Head Lice
Wet combing (the most reliable home method)
Wet combing physically removes the lice and eggs and is safe to repeat as often as needed. Here is the method:
- Wash and wet the hair, then apply lots of conditioner — this stuns the lice and helps the comb glide.
- Using a fine-tooth lice comb (kanghi), comb the hair section by section, from the scalp to the tips. Work through the whole head methodically so you do not miss patches.
- Wipe the comb on a tissue or paper after each stroke to check for lice and nits, and to remove what you have caught.
- Rinse out the conditioner once you have combed the entire head.
- Repeat every few days for about two weeks. This timing matters: it catches young lice that hatch from eggs you may have missed, before they can lay new eggs and start the cycle again.
Medicated lotions and shampoos
There are medicated anti-lice lotions and shampoos available over the counter and on a doctor’s advice. If you use one:
- Follow the product or doctor’s instructions exactly — how to apply, how long to leave it on, and whether to repeat.
- Check the right age: some products are not suitable for very young children or babies, so read the label or ask your pharmacist or doctor.
- It is still worth combing through afterwards to remove dead lice and nits.

Around the house
Wash recently-used bedding, towels, hats and pillowcases in hot water. There is no need to deep-clean the whole house — lice do not survive long away from the scalp. Check other family members and treat those who actually have lice; do not blanket-treat everyone with medicine when they are not affected.
What About Home Remedies?
You may have heard about oiling the hair and combing it out. Coconut or other hair oils can make the hair slippery and help loosen lice and nits so the comb catches more — and oiling and combing is a long-standing Indian habit that fits naturally with wet combing. But understand that the combing is what removes the lice, not the oil itself. The oil is a helper, not a cure.
Be cautious about applying strong or unproven substances (such as harsh chemicals or undiluted essential oils) to a child’s scalp — they can irritate the skin without reliably killing lice. When in doubt, stick with the wet-combing method or a proper medicated product.
Prevention
You cannot bubble-wrap a child, but you can lower the risk:
- Avoid head-to-head contact during play where possible.
- Don’t share combs, brushes, hats, caps, hairbands, helmets or pillows.
- Tie long hair back (a plait or bun) for school and crowded outings.
- Check the hair regularly, especially if there is a lice outbreak at school — catching it early makes treatment far easier.
When to See a Doctor
Most lice can be handled at home, but see your paediatrician if:
- The scalp looks infected from heavy scratching — red, weepy, sore, crusted, or with swollen glands in the neck.
- Treatment is not working even after you have used it correctly and combed thoroughly.
- Your child is a very young child or baby with lice, where you should not use a product without medical advice.
- You are unsure which product is safe for your child’s age.
The Indian Context
Lice spread quickly in Indian schools, where outbreaks move through a classroom in days. The good news is that the traditional tools work: a fine-tooth kanghi, regular oiling and combing, and an extra family member to help section the hair are exactly what wet combing needs. Long, oiled hair is common, so make checking the scalp part of the routine — and please, drop the shame. Lice are a normal part of childhood, not a verdict on your home. Treating them calmly and quickly, and telling the school or other parents so everyone can check, is what actually stops the cycle.
Frequently Asked Questions
Q: Does my child have lice because our home isn’t clean?
A: No. Lice have nothing to do with cleanliness — they are just as happy in freshly washed hair. They spread through head-to-head contact, which is normal among children.
Q: How long does it take to get rid of head lice?
A: With consistent wet combing every few days for about two weeks (or a medicated product used as directed), most cases clear up. The two-week window matters because it catches newly hatched lice.
Q: Do I need to treat the whole family?
A: Check everyone, but only treat those who actually have lice. Blanket-treating people without lice is unnecessary.
Q: Will cutting my child’s hair short get rid of lice?
A: It isn’t necessary. Lice live near the scalp, so even short hair can carry them. Wet combing or a medicated product works regardless of hair length.
Q: Can lice spread disease?
A: No. Head lice do not spread any disease. The main issue is an itchy scalp and, occasionally, skin irritation from scratching.
