What Are Head Lice?

Head lice are tiny, parasitic insects that live on the scalp and feed on human blood. They spread through direct head-to-head contact and occasionally through shared items like hats, brushes, or bedding. Lice cannot jump or fly, making close physical proximity the primary mode of transmission.

Lifecycle: Egg (nit) → nymph → adult louse
Size: Adults are about the size of a sesame seed
Lifespan: 30 days on the scalp, lay up to 10 eggs per day

Signs and Symptoms of Lice Infestation

Detecting lice early is crucial for effective treatment. Common signs include:

Intense itching, especially behind the ears and at the nape of the neck
A crawling sensation on the scalp
Presence of nits (white/yellow eggs) close to the scalp
Red bumps or sores caused by scratching

Types of Lice Treatments

A. Over-the-Counter (OTC) Treatments

These are widely available at pharmacies and are typically the first line of defense:

Permethrin Lotion (1%): FDA-approved and safe for children over 2 months.
Pyrethrins with Piperonyl Butoxide: Natural extracts from chrysanthemums; effective but may require repeat applications.

B. Prescription Medications

For stubborn infestations or resistant lice, prescription treatments are recommended:

Ivermectin (Sklice): Kills lice without needing to comb out nits.
Malathion (Ovide): Strong insecticide, flammable, not for young children.
Spinosad (Natroba): High success rate, safe for children over 6 months.

C. Natural Remedies

Some parents prefer chemical-free alternatives:

Tea Tree Oil & Neem Oil: Natural insecticides but may cause allergic reactions.
Mayonnaise or Petroleum Jelly: Aim to suffocate lice, but effectiveness is not scientifically proven.

Wet-Combing Method

A popular chemical-free technique:

Apply conditioner on wet hair
Use a fine-toothed lice comb to remove lice and nits
Repeat every 3–4 days for 2 weeks

Best suited for children under 2 and individuals with sensitive skin.

How to Use Lice Treatments Effectively

Follow these best practices for successful treatment:

Read all instructions carefully
Apply the product for the recommended duration
Rinse thoroughly and use a lice comb to remove dead lice/nits
Repeat treatment after 7–10 days (if needed)
Avoid mixing multiple treatments simultaneously

Environmental Cleaning After Treatment

Lice don’t survive long off the human body, but cleaning is essential:

Wash bedding, clothes, and stuffed animals in hot water
Dry on high heat
Vacuum carpets, couches, and car seats
Seal unwashable items in plastic bags for 2 weeks

When to Seek Professional Help

Lice persist after multiple treatments
Scalp becomes infected or severely irritated
You’re unsure about which treatment is safest (e.g., for infants or pregnant women)

Visit a pediatrician or dermatologist for expert guidance.

Lice Prevention Tips

Prevention is better than cure:

Avoid head-to-head contact during play or sports
Don’t share personal items like combs or hats
Do regular head checks, especially after sleepovers or camps
