Diagnosis of pediculosis is primarily through visual inspection. Nurses should look for live lice or their eggs, known as nits, attached to the hair shafts. Nits are tiny, oval, and usually yellow or white, often confused with dandruff but firmly attached to the hair. A fine-toothed lice comb can assist in detecting lice and nits. It is crucial to differentiate between active infestation and residual nits from a previous infestation.
