How can you check your own head for lice? - briefly
Part your hair into small sections, run a fine-tooth comb from the scalp outward under bright light, and examine the comb and hair shafts for live insects or oval, brown‑colored nits attached within a quarter‑inch of the scalp. Repeat the process across the entire head to ensure thorough detection.
How can you check your own head for lice? - in detail
Inspecting your scalp for lice requires a systematic approach, proper lighting, and the right tools. Begin by selecting a bright, natural light source or a lamp with a magnifying attachment. Use a fine-toothed comb designed for lice detection; the teeth should be spaced closely enough to catch both adult insects and nits attached to hair shafts.
- Prepare the hair. Dampen it with water or a light conditioner to reduce slip and make the strands easier to separate. Avoid heavy oils, which can conceal insects.
- Section the hair. Divide the scalp into quadrants—front, crown, sides, and back—and secure each section with clips or hair ties. This ensures thorough coverage.
- Comb through each section. Starting at the scalp, pull the comb down to the ends in a single, smooth motion. After each pass, wipe the comb on a white tissue or a damp paper towel to reveal any captured organisms.
- Examine the comb. Look for live lice (brown or gray, about the size of a sesame seed) and nits (tiny, oval, and firmly attached to the hair shaft within ¼ inch of the scalp). Do not confuse dandruff or hair fibers with nits; nits are glued to the hair and do not easily slide off.
- Repeat the process. Perform three consecutive passes per section, then re‑examine the entire scalp. Multiple passes increase detection accuracy, especially in dense or curly hair.
- Document findings. Note the locations where lice or nits were observed, the quantity, and any signs of irritation. This information guides treatment decisions and follow‑up checks.
After the initial inspection, repeat the self‑examination every 2–3 days for at least two weeks, as lice eggs hatch within 7–10 days. Consistent monitoring catches new infestations early and confirms the effectiveness of any treatment applied.
