How to Get Rid of Head Lice
Head lice. Is it cause for real concern? For some, there’s an “ick” factor associated with a head of lice that invokes creepy, crawly bugs. But these tiny insects, more formally known as the “head louse”, are a very common problem across the United States, especially for children. Before diving headfirst into the itch-inducing subject of lice, we should understand what they are and why they’ve become such an unwelcome guest in many homes. The term “louse” is the singular form of adult lice.
The Issue of Head Lice Infestation
First, the head louse is a small, wingless insect that thrives on the human scalp. It’s not a reflection of hygiene or cleanliness, but rather an unfortunate outcome of direct head-to-head contact. Children, given their close contact in play settings and schools, are often the most susceptible to these infestations. The sight of a child scratching their head incessantly might be a sign to look closer.
At Metro Pediatrics, we’ve got years of experience attending to various children’s health issues, including head lice infestations. We’ll guide parents and caregivers through the confusing and often alarming journey of tackling head lice.
In this article, we’ll tackle the anatomy of a louse, their life cycle, and most important, effective strategies to send them away!
Understanding Head Lice: Anatomy and Life Cycle
To effectively treat a head lice infestation, it’s vital to understand the creature: its structure, life stages, and habits.
Adult Lice and Live Lice: Adult lice are tiny but visible to the naked eye, often the size of a sesame seed. They vary in color from tan to brownish-gray. Live lice move quickly, making them challenging to catch and spot, especially in a child’s thick hair. They are most active in the dark and avoid light, which can make nighttime especially active for the little things,
Lice Eggs (Nits): One of the defining characteristics of an ongoing infestation is the presence of lice eggs, often called nits. Nits are oval and about the size of a pinhead. They cling stubbornly to the hair shaft, especially near the scalp for warmth. Their color ranges from yellowish-brown when alive to pearly white once they are empty shells.
The Life Cycle of Lice: The lifecycle of a head louse can be segmented into three primary stages – egg, nymph, and adult. From the egg, a nymph emerges, which is an immature louse. Over a period of 9-12 days, this nymph goes through three molting stages before reaching adulthood. Adult lice can live up to 30 days on a person’s scalp, feeding on tiny amounts of blood. During their short lifespan, a female louse can lay up to six eggs per day, making prompt treatment paramount.
Lice Transmission: Contrary to many myths, lice cannot fly or jump. Their primary mode of spreading is through direct head-to-head contact. This is why close contact activities like hugging, sharing a bed, or playing contact sports can easily spread lice among children. Indirect transmission, such as through sharing hats or hair brushes, is less common but still possible. Some children get lice by sharing pillows, laying together on soft fabric furniture, or head to head on a rug at school.
Natural and Home Remedies for Lice Treatment
Having head lice can be a distressing experience for both children and adults. While there are numerous medical treatments available, many parents are increasingly looking towards natural and home remedies as a first line of defense. These treatments, when applied correctly, can be both safe and effective.
Wet Combing: This method is all about manual removal. By using a nit comb or a fine-toothed comb, parents can systematically comb through wet hair to remove both adult lice and their eggs. It’s essential to ensure the hair is damp and slightly conditioned, which can immobilize the lice, making them easier to catch. Wet combing should be done daily for about two weeks to ensure all lice and nits are removed.
Olive Oil: This kitchen staple can be a potent weapon against head lice. When applied generously to the scalp and hair, olive oil can suffocate adult lice and nymphs, preventing them from feeding and reproducing. After leaving it on overnight (with the head covered with a shower cap), parents can comb out the dead lice in the morning. For optimal results, it’s best to repeat this process for several nights.
Petroleum Jelly: Similar to olive oil, petroleum jelly can also suffocate lice when applied thickly on the scalp. However, its thicker consistency means it can be more challenging to wash out. Keeping it on overnight and combing the hair in the morning can help in removing the lice.
Essential Oils: Some essential oils, like tea tree, lavender, and eucalyptus, have been touted to repel lice and even kill them. Oils must be mixed with a carrier oil (like coconut oil) before applying to the scalp, so the previous mention of olive oil can be just as effective. Use essential oils with caution in children, always conduct a patch test first, and check with your doctor before applying.
Home Remedies and Their Role: While home remedies can be effective, they often require diligence and repetition. They are best used as preventive measures or in combination with over-the-counter treatments for maximum efficacy. It’s crucial for parents to consult with a child’s doctor or a trusted healthcare provider, such as the experienced team at Metro Pediatrics, before starting any home-based treatment. This ensures that the chosen method is safe and suitable for the child’s specific needs.
Over-the-Counter and Prescription Treatments for Head Lice
For some families, natural remedies may not provide the quick relief they desire or might not be effective enough to handle a full-blown infestation. In such cases, over-the-counter (OTC) and prescription treatments come to the rescue, offering robust solutions backed by science.
OTC Lice Treatments:
- Medicated Shampoos and Cream Rinses: Available at most drugstores, these products are designed to kill lice on humans. Typically, they contain an insecticide that affects the nervous system of the lice with no harm to the person. It’s essential to follow the product’s instructions closely and ensure that it’s suitable for the child’s age.
- Lice Treatment Kits: Comprehensive kits often come with a medicated solution, a fine-toothed comb or lice comb, and sometimes additional items like a magnifying glass or protective cap. These kits aim to offer an all-in-one solution for families dealing with lice. Call your doctor with any questions about safety.
Prescription Lice Treatments:
- Topical Ivermectin: A single-application treatment, this lotion kills lice by affecting their nervous system. Unlike some other treatments, it can also tackle lice eggs, reducing the need for follow-up applications. This can be challenging to get covered by insurance.
Precautions & Follow-Up:
- Reading Labels: Always read and follow the instructions on the product label. This ensures that the treatment is applied correctly and safely.
- Second Treatment: Regardless of the method chosen, a second treatment is often recommended after 7 to 10 days to kill any lice that might have hatched from missed eggs.
- Consultation: Before starting any OTC or prescription treatment, consult a health care provider or a child’s doctor. At Metro Pediatrics, our team is well-versed in the variety of treatments available and can provide guidance tailored to each child’s specific needs.
Dealing with Side Effects
While these treatments are generally safe, there’s always a potential for side effects, like skin irritation or an allergic reaction. It’s important to monitor the child’s scalp and overall health closely during and after treatment.
Preventing Future Infestations: Tips and Best Practices
After the challenge of treating a head lice infestation, the last thing any parent or caregiver wants is a recurrence. The key to avoiding future outbreaks lies in understanding prevention. Metro Pediatrics shares the following expert-backed strategies to help keep these pesky invaders at bay.
Avoid Direct Contact
Since lice primarily spread through direct head-to-head contact, teach children to be cautious during playtime, sleepovers, and group activities. Simple gestures, like avoiding leaning heads together during a selfie or while reading a book, can make a significant difference.
Personal Items
Stress the importance of not sharing items that touch the head. This includes combs, hats, headphones, hair accessories, and towels. If a family member is undergoing treatment, make sure to keep their personal items separated.
Regular Checks
Routine checks, especially for households with school-going children, can catch a potential infestation before it gets out of hand. Using a lice comb or a fine-toothed comb on damp hair, inspect the scalp and hair for any signs of lice or nits at least once a week.
Educate About Lice
Dispelling myths and misconceptions about lice can reduce panic and stigma. Teach children that anyone can get lice, and it’s not indicative of their cleanliness or hair type. It’s a common childhood challenge and not a sign of poor hygiene. It’s important to not make a child feel they or their family is at fault for getting lice or spreading it.
Cleaning Measures
While lice don’t survive long away from the human scalp, it’s a good practice to clean items that the infested person used before treatment. This includes washing bedding and clothing in hot water, vacuuming furniture and floors, and sealing non-washable items in a plastic bag for two weeks.
Stay Informed
With children in school, always stay updated with any lice outbreaks and follow the school’s guidelines and recommendations. Schools often have protocols in place that help contain and manage infestations.
