How to Get Rid of Them and Stop Them Coming Back

Head lice are a common problem, especially among children, but they can affect anyone. These tiny, wingless insects feed on human blood and live close to the scalp. While they are not dangerous, they can be extremely itchy and annoying, and they spread easily through close contact. In this guide, we’ll explore everything you need to know about getting rid of head lice and preventing them from coming back.

What Are Head Lice?

Head lice (Pediculus humanus capitis) are small parasitic insects that live on the scalp and hair. They are about the size of a sesame seed and are usually grayish-white or tan in color. Lice do not have wings and cannot fly or jump, but they move quickly through hair, and their eggs (nits) are firmly attached to hair shafts near the scalp.

Signs and Symptoms of Head Lice

Intense itching, especially behind the ears and at the nape of the neck
Small red bumps on the scalp, neck, and shoulders
Presence of lice eggs (nits) on hair shafts
Feeling something moving in the hair

How Head Lice Spread

Head lice spread primarily through direct head-to-head contact. They are common in schools and daycare centers where children play closely together. Lice can also spread via:

Sharing combs, brushes, hats, or headphones
Close contact with infested bedding or towels

Lice cannot jump or fly, and they do not infest pets. They survive only on human blood, so infestations are always linked to human contact.

How to Get Rid of Head Lice

Getting rid of head lice involves killing the lice and removing the nits from the hair. There are several effective methods, including medicated treatments, natural remedies, and manual removal.

1. Over-the-Counter (OTC) Treatments

OTC lice shampoos and lotions usually contain permethrin or pyrethrin, which are safe for most people and effective when used correctly.

Steps for OTC treatment:

Apply the shampoo or lotion according to the instructions.
Leave it on for the recommended time.
Rinse thoroughly and dry the hair.
Use a fine-toothed lice comb to remove dead lice and nits.
Repeat the treatment after 7–10 days to kill newly hatched lice.

Tips:

Avoid using excessive amounts of product.
Do not treat your child more than twice unless directed by a doctor.

2. Prescription Treatments

If OTC treatments fail, a doctor may prescribe stronger medications such as:

Malathion lotion
Benzyl alcohol lotion
Ivermectin lotion

These treatments are usually more potent and effective against lice that are resistant to OTC products.

3. Manual Removal

Combing out lice and nits is labor-intensive but highly effective, especially for young children or those who cannot use chemical treatments.

How to comb for lice:

Wet the hair and apply a generous amount of conditioner.
Use a fine-toothed lice comb, starting at the scalp and moving to the ends.
Wipe the comb on a tissue or rinse frequently.
Repeat every 2–3 days for at least two weeks.

Home Remedies for Head Lice

Some people prefer natural or home remedies. While they may not be as scientifically proven as medicated treatments, they can help as part of a comprehensive approach.

1. Essential Oils

Certain essential oils, like tea tree oil, lavender oil, and neem oil, have been reported to repel lice. Always dilute essential oils before applying them to the scalp.

How to use:

Mix a few drops of essential oil with a carrier oil (like coconut oil).
Massage gently into the scalp and leave for 30 minutes.
Comb and wash the hair thoroughly.

2. Coconut Oil

Coconut oil can help smother lice and make combing easier. Apply generously, leave it on for at least 30 minutes, and comb the hair.

3. Vinegar

Vinegar is sometimes used to loosen nits from hair shafts. After applying vinegar, comb the hair thoroughly with a lice comb.

Note: Home remedies are best combined with combing and proper hygiene. They may not fully eliminate infestations on their own.

Cleaning Your Home to Prevent Reinfestation

Head lice do not survive long off the scalp, but they can cling to combs, brushes, hats, and bedding. To prevent reinfestation:

Wash bedding, towels, and clothes in hot water and dry on high heat.
Soak combs, brushes, and hair accessories in hot water for 10–15 minutes.
Vacuum carpets, upholstered furniture, and car seats.
Items that cannot be washed can be sealed in a plastic bag for 48 hours to kill lice.

Tip: There’s no need for expensive fumigation sprays—they are usually unnecessary and not recommended.

Preventing Head Lice in the Future

Prevention is key to avoiding repeat infestations. Here are strategies to keep lice away:

1. Avoid Head-to-Head Contact

Encourage children to avoid touching heads, especially during play, sports, or group activities.

2. Do Not Share Personal Items

Teach children not to share combs, brushes, hats, hair accessories, or headphones.

3. Regular Hair Checks

Check your child’s hair weekly for lice, especially behind the ears and at the nape of the neck.

4. Keep Hair Tied Up

For long hair, tying it back in braids or ponytails can reduce the risk of contact with lice.

5. Inform Close Contacts

If a family member has lice, inform schools, daycare, and close friends so they can check for infestations.

When to See a Doctor

Most head lice infestations can be treated at home, but you should see a doctor if:

OTC treatments do not work after two rounds
The scalp becomes red, swollen, or infected
Your child has a severe allergic reaction to lice products

A doctor can prescribe stronger medications and provide guidance for persistent cases.

Common Myths About Head Lice

Myth 1: Head lice only affect dirty hair

Fact: Lice infest clean and dirty hair equally. Hair hygiene does not prevent lice.

Myth 2: You can get lice from pets

Fact: Head lice only live on humans, not animals.

Myth 3: Cutting hair short prevents lice

Fact: Lice can infest hair of any length, though short hair may make them easier to remove.

Tips for Parents

Dealing with head lice can be stressful, but staying calm and systematic helps:

Treat all infested family members at the same time.
Wash bedding and personal items promptly.
Keep children home from school until they have been treated.
Use a fine-toothed comb regularly to remove nits.

Conclusion

Head lice are common and highly contagious, but they are manageable with the right approach. A combination of medicated treatments, careful combing, and hygiene practices usually eliminates lice completely. Preventing reinfestation involves vigilance, regular hair checks, and educating children about avoiding head-to-head contact. By staying informed and proactive, you can keep your family lice-free and avoid the frustration of recurring infestations.
