How can I find out if I have lice myself? - briefly
Examine the scalp and hair under bright light, searching for live insects about the size of a sesame seed, translucent eggs (nits) attached close to the hair shaft, and signs of itching or redness. Run a fine‑toothed comb through wet, conditioned hair to capture any lice or nits for confirmation.
How can I find out if I have lice myself? - in detail
A thorough self‑examination begins with a careful visual inspection of the scalp and hair. The hair should be part‑by‑part separated using a fine‑tooth comb, ideally a lice‑comb with teeth spaced 0.2–0.3 mm apart. The comb is drawn through each section from the scalp outward, then the hair is examined for live insects or their eggs.
Key indicators to observe:
- Small, grayish‑brown insects about the size of a sesame seed, moving quickly across the hair shaft.
- Oval, white or yellowish nits attached firmly to the hair shaft within ¼ inch of the scalp. Nits have a blunt, chalky appearance, whereas hair‑shed shells are translucent and easily removed.
- Intense itching, especially behind the ears, at the nape of the neck, and near the hairline. Scratching may cause small red bumps or secondary infection.
If visual confirmation proves difficult, a magnifying lens (10×) can enhance detection of nits and adult lice. Some over‑the‑counter kits contain a small vial of liquid that, when applied to a few hairs, makes lice more visible under a handheld microscope.
Professional confirmation may be sought from a dermatologist or school health nurse. These experts can employ a portable dermatoscope, providing a clear view of the scalp surface and allowing rapid identification of infestation.
After detection, immediate steps include:
- Washing all bedding, clothing, and personal items in hot water (≥ 60 °C) and drying on high heat.
- Isolating untreated hair accessories and cleaning them with hot, soapy water.
- Initiating appropriate treatment, such as a pediculicide shampoo or lotion, following the product’s instructions for duration and repeat application.
- Re‑examining the scalp after 7–10 days to ensure eradication, using the same combing method.
Regular follow‑up examinations every two to three days during the treatment period help prevent reinfestation and confirm the success of the intervention.
