How can I find out if I have lice on my head? - briefly
Examine the scalp and hair using a fine‑toothed comb, searching for live lice, nits glued within a millimeter of the scalp, or persistent itching. If visual confirmation is unclear, apply an over‑the‑counter detection product or consult a healthcare professional for a definitive assessment.
How can I find out if I have lice on my head? - in detail
To verify the presence of head‑lice, follow a systematic examination.
First, inspect the scalp in a well‑lit area. Part the hair close to the skin using a fine‑toothed comb or a clean pencil. Examine the sections for live insects, which appear as small, tan‑brown bodies about the size of a sesame seed, and for translucent, oval eggs (nits) attached firmly to hair shafts within a half‑inch of the scalp.
Second, check for characteristic symptoms: persistent itching, especially behind the ears or at the nape; visible specks of blood or dark spots on clothing; and a feeling of movement on the scalp.
Third, employ a detection method if visual confirmation is difficult. Use a commercial lice detection kit that contains a comb with teeth spaced 0.2 mm apart. Comb each section from the root outward, wiping the comb on white paper after each pass to reveal any captured insects or nits.
Fourth, consider a professional assessment. Dermatologists, pediatricians, or trained school nurses can perform a thorough scalp examination and provide a definitive diagnosis.
Finally, document findings. Photograph any observed lice or nits for reference, especially if treatment will be administered by a healthcare provider.
By adhering to these steps—visual inspection, symptom review, combing with a detection tool, and professional verification—you can accurately determine whether head‑lice are present.
