Who checks a head for lice? - briefly
Usually a parent, caregiver, or school nurse inspects the hair during routine screenings, often using a fine-tooth comb to detect lice. Professional lice‑removal services may also be hired for a thorough examination.
Who checks a head for lice? - in detail
Parents or guardians typically perform the first examination, using a fine-toothed comb on damp hair to detect live insects or viable eggs. Schools often delegate this responsibility to trained staff members—usually school nurses or designated teachers—who follow district‑approved protocols. In many jurisdictions, a certified health professional, such as a pediatrician, dermatologist, or public health nurse, conducts a more thorough assessment when an infestation is suspected or confirmed. Commercial pest‑control technicians may be called in for large‑scale outbreaks in childcare facilities, applying specialized detection tools and treatment plans.
The inspection process follows a standard sequence:
- Preparation – Hair is wet, conditioned, and detangled to allow the comb to pass through strands without resistance.
- Visual scan – Examiner looks for adult lice, nymphs, or viable nits attached close to the scalp, especially behind ears, at the nape, and in the crown region.
- Combing – A metal or plastic lice comb is drawn from the scalp outward in systematic rows, with each pass examined under adequate lighting.
- Documentation – Findings are recorded, noting the number and location of live insects and nits; photographs may be taken for medical records.
- Follow‑up – If live lice are found, the examiner initiates treatment, provides education on hygiene and environmental measures, and schedules re‑examination after 7–10 days to confirm eradication.
Guidelines from health agencies recommend routine checks at the start of the school year, after vacations, and whenever a case is reported. Frequency may increase in communities with high prevalence. Professional training emphasizes the distinction between viable nits (firmly attached to the hair shaft) and shed shells, reducing false‑positive diagnoses.
