Head lice spread quietly through confusion and delay, often missed because itching doesn’t appear right away and myths about who gets lice persist. Careful checking with a fine-toothed comb and acting when live lice are found matters more than panic or extreme cleaning. Consistent treatment—whether medicated products or thorough wet-combing—plus notifying schools and reducing head contact usually stops the cycle, turning a stressful situation into a short, manageable problem.
