How can lice be noticed in children? - briefly
Persistent scalp itching, especially after several days, often signals an infestation; a thorough inspection of the hair should reveal tiny, oval, white‑to‑yellow nits firmly attached within a quarter‑inch of the scalp. Live lice appear as gray‑brown, slow‑moving insects that can be seen crawling on the hair shafts or scalp.
How can lice be noticed in children? - in detail
Lice infestations in youngsters become apparent through several observable signs. The most reliable indicator is the presence of live insects moving on the scalp or hair shafts. These insects are about the size of a sesame seed, gray‑brown, and may be seen crawling, especially when the child’s head is examined under good lighting.
Itching is another common symptom. The irritation results from an allergic reaction to lice saliva. Children often scratch their heads, and the scalp may show small red bumps or areas of inflammation. Persistent scratching, especially after a short period of exposure, should raise suspicion.
Nits—unhatched eggs—are a definitive clue. They appear as tiny, oval, yellow‑white or brownish dots attached firmly to the hair shaft, usually within a half‑inch of the scalp. Unlike dandruff, nits cannot be brushed away easily and are positioned at a slight angle to the hair. A careful combing with a fine‑toothed lice comb can reveal clusters of nits close to the scalp.
Additional clues include:
- Small blood stains on pillows or clothing, caused by lice biting and the child’s subsequent scratching.
- A “dry” or “crusty” feeling on the scalp, resulting from excess saliva or debris left by the insects.
- Sudden onset of scalp discomfort without an apparent dermatological cause.
To confirm an infestation, isolate a section of hair, hold it close to the eye, and look for the characteristic shape and movement of the insects. Using a magnifying glass or a bright lamp can improve detection accuracy. If live lice or viable nits are found, treatment should begin promptly to prevent spread.
