How to independently check for lice? - briefly

Wet the hair, apply conditioner, and run a fine‑toothed lice comb from scalp to ends, wiping the comb after each pass to detect live insects and attached eggs; repeat the examination after 48–72 hours to catch any newly hatched nits.

How to independently check for lice? - in detail

Detecting head‑lice infestations without professional assistance requires a systematic approach and the right tools. Begin with a clean, well‑lit environment; natural daylight or a bright lamp reduces visual distortion. Use a fine‑toothed comb specifically designed for lice, with teeth spaced 0.2–0.3 mm apart, and a white, non‑slippery surface such as a disposable towel or a sheet of white paper.

  1. Prepare the hair.
    • Separate the hair into sections of 2–3 cm using hair clips or elastic bands.
    • Apply a small amount of conditioner or a water‑based detangling spray to each section; this immobilises insects and makes combing smoother.

  2. Comb each section.
    • Starting at the scalp, draw the comb through the hair down to the ends in a single, steady motion.
    • After each pass, wipe the comb on the white surface, then examine it with a magnifying lens (10× is sufficient).

  3. Identify findings.
    • Live lice appear as tan‑brown, wingless insects about 2–4 mm long; they move quickly when disturbed.
    • Nits (lice eggs) are oval, 0.8 mm, and firmly attached to the hair shaft, usually within 1 cm of the scalp. They are translucent at first, turning gray or brown as they mature.

  4. Document results.
    Record the number of live insects and nits per section.
    • If any live lice are observed, repeat the combing process on the same area to ensure none are missed.

  5. Follow‑up.
    • Conduct a second inspection 48 hours after the first, because newly hatched lice may emerge from surviving nits.
    • Continue daily checks for at least one week, focusing on the nape, behind the ears, and the crown, which are common habitats.

Additional tips: avoid using bright hair products that can obscure visibility; wear a disposable cap or headscarf on the combed area to prevent cross‑contamination; and keep the comb sanitized between uses by soaking it in hot, soapy water for several minutes. By adhering to this methodical routine, individuals can reliably confirm the presence or absence of head‑lice without external help.
