How can you realize that you have lice? - briefly
Intense scalp itching, especially after washing, often indicates an infestation. Close inspection of hair near the roots reveals tiny, oval nits firmly attached to strands and, at times, live insects moving rapidly.
How can you realize that you have lice? - in detail
Recognizing a head‑lice infestation requires careful observation of the scalp and hair. The following signs indicate the presence of these parasites:
- Small, elongated insects about the size of a sesame seed moving on the scalp.
- White, oval‑shaped eggs (nits) firmly attached to hair shafts, typically within a half‑inch of the scalp.
- Itching or a crawling sensation on the scalp, especially after prolonged periods without washing.
- Red or irritated patches on the neck, shoulders, or behind the ears caused by scratching.
- Presence of live lice or nits when a fine‑toothed comb is drawn through damp hair.
To confirm the condition, perform a systematic inspection:
- Separate small sections of hair, starting at the crown and moving outward.
- Use a magnifying lens if available to examine each strand closely.
- Run a lice comb from the scalp toward the tip, wiping the comb on a white tissue after each pass.
- Observe the tissue for live insects or brown‑black specks, which are crushed nits.
If live lice or viable nits are found, treatment should begin promptly. Cleaning personal items (combs, hats, bedding) and notifying close contacts reduce the risk of re‑infestation. Regular follow‑up inspections over the next two weeks ensure that all stages of the parasite have been eliminated.
