How can you check for lice yourself? - briefly

Use a fine‑tooth comb on dry or slightly damp hair, separating the hair into small sections and pulling each section close to the scalp to expose any lice or attached eggs. Examine the comb and hair for live insects, translucent nits within a quarter‑inch of the scalp, or visible movement.

How can you check for lice yourself? - in detail

Detecting head lice without professional assistance requires a systematic approach, proper lighting, and appropriate tools. Begin by selecting a well‑lit area, preferably with natural daylight or a bright lamp. Use a fine‑toothed comb designed for lice detection; its teeth are spaced about 0.2 mm apart, allowing capture of both adult insects and nymphs.

1. Prepare the scalp

   • Apply a conditioner or a small amount of water to soften the hair and reduce tangles.
   • Separate the hair into manageable sections using hair clips or rubber bands.

2. Examine each section

   • Starting at the crown, pull a section away from the scalp and run the comb from the root to the tip in a single, smooth motion.
   • After each pass, wipe the comb on a white paper towel or place it on a white surface to enhance visibility of any captured organisms.
   • Repeat the process for every section, moving outward toward the ears, neckline, and behind the ears, as these regions are common infestation sites.

3. Identify findings

   • Adult lice appear as tan or grayish insects, 2–4 mm long, with six legs.
   • Nymphs are smaller, translucent, and less than 2 mm.
   • Viable eggs (nits) are oval, 0.8 mm long, firmly attached to the hair shaft within 1 cm of the scalp; they appear white or yellowish and do not slide when the hair is gently tugged.

4. Confirm presence

   • If any live lice or viable nits are observed, repeat the combing procedure on a second day to verify persistence, as newly hatched nymphs may emerge after 7–10 days.
   • Absence of live insects but presence of empty shells (nits that have been removed from the scalp) suggests a recent infestation that may be resolving.

5. Document results

   • Record the number of lice, nits, and their locations for reference during treatment and follow‑up checks.
   • Photograph the findings if visual confirmation is needed for medical consultation.

6. Post‑examination hygiene

   • Wash the comb in hot, soapy water.
   • Launder clothing, bedding, and personal items used during the examination at temperatures of at least 60 °C or seal them in a plastic bag for two weeks to eliminate any surviving stages.

Consistent self‑inspection every 2–3 days for two weeks, combined with proper treatment, provides reliable detection and control of head lice infestations.
