pinsettiä

Pinsetti, also known as *Pediculus humanus capitis*, is a common external parasite that infests the human scalp. It is a wingless insect measuring about 2-3 millimeters in length, with a grayish-white or tan appearance. Adult lice lay tiny oval eggs called nits, which are firmly attached to the hair shafts close to the scalp. Nits are difficult to remove and often mistaken for dandruff or other debris.

Infestation, known as pediculosis capitis, is spread through direct head-to-head contact. It is not related to poor hygiene and can affect people of all socioeconomic backgrounds. The primary symptom of a pinsetti infestation is itching, which can be intense and lead to scratching. This scratching can sometimes result in secondary bacterial infections of the skin.

Diagnosis is typically made by visually identifying live lice or viable nits on the scalp. Treatment involves using over-the-counter or prescription medicated shampoos, lotions, or rinses designed to kill lice. It is crucial to follow the product instructions carefully and repeat treatment as recommended, as some treatments may not kill all nits or newly hatched lice. Combing the hair with a fine-toothed comb after treatment is also an important step in removing dead lice and nits. Environmental decontamination, such as washing bedding and clothing in hot water, is generally not considered essential for treating head lice but can help prevent re-infestation.
