How to examine the head for lice? - briefly
Part the hair with a fine-tooth comb, starting at the scalp and moving outward, inspecting each section for live insects or nits attached within 1 mm of the shaft. Examine the neck, behind the ears, and the nape, then repeat the inspection after a few days to verify clearance.
How to examine the head for lice? - in detail
A thorough scalp inspection begins with a well‑lit environment. Use a bright lamp or natural daylight and a clean, flat surface where the person can sit comfortably. Gather a fine‑tooth lice comb, a magnifying glass (optional), disposable gloves, and a white towel or paper to catch any debris.
First, dampen the hair with a spray bottle or a light conditioner. Wet hair makes nits easier to see because they cling more tightly to the shaft when moist. Separate the hair into sections: start at the crown, then move to the sides, back, and nape. Secure each section with a clip or rubber band before examining it.
For each section, follow these steps:
- Part the hair close to the scalp with a fine comb, pulling the strand away from the skin.
- Run the lice comb from the scalp outward, moving slowly to avoid breaking nits.
- After each pass, wipe the comb on a white tissue or towel; any attached particles become visible against the light background.
- Inspect the tissue for live insects (tan‑brown, about the size of a sesame seed) and for oval, yellow‑white eggs attached within ¼ inch of the scalp.
- Use the magnifying glass to verify the presence of nits, distinguishing them from dandruff by their firm attachment and lack of a flaky appearance.
Repeat the process for every section, ensuring no area is missed. After the inspection, place the comb in a sealed container and wash it in hot, soapy water for at least ten minutes. Dispose of any captured insects and nits by sealing them in a plastic bag before discarding.
Document findings immediately: note the number and location of live lice and nits, the condition of the hair (e.g., tangled, short), and any signs of irritation. Schedule a follow‑up examination in 7‑10 days to catch newly hatched lice, as treatment often does not affect eggs.
Finally, cleanse the environment. Wash bedding, hats, and hair accessories in hot water (≥ 130 °F) or seal them in a plastic bag for two weeks. Vacuum carpets and upholstered furniture to remove stray hairs that may harbor nits. Consistent, systematic checks combined with proper hygiene eliminate the infestation efficiently.
