päätäit
Päätäit, also known as head lice, are small parasitic insects that infest the human scalp. These tiny wingless insects feed on human blood and can cause discomfort and itching. Päätäit spread through direct head-to-head contact or by sharing personal items such as combs, hats, or pillows. The eggs, called nits, are laid close to the scalp and hatch in about a week. Infestations are common among children, particularly in school settings, but can affect anyone regardless of hygiene practices. Symptoms include persistent itching on the scalp, visible movement in the hair, and the presence of nits attached to hair shafts near the scalp. Treatment typically involves over-the-counter or prescription medicated shampoos and thorough combing with a fine-toothed comb. Washing bedding, clothing, and personal items in hot water and vacuuming upholstered furniture can help eliminate any remaining lice or nits. Regular checks, especially for children, can help detect infestations early. While päätäit can be a nuisance, they do not transmit diseases and can be effectively treated with proper care and attention.
