2. Common Culprits
The most frequent pest in children’s hair is head lice—tiny, wingless insects about 2–3 mm long. Their eggs (nits) stick firmly to hair shafts. Less commonly, mites such as scabies can affect the scalp. Scabies mites are smaller (0.2–0.4 mm) and usually burrow into skin folds, though scalp involvement can occur.
