It is empty after hatching, unlike live nits, which are close to the root and translucent.<\/div><\/div>\n\n\n\n<div class=\"wp-block-faq-block-for-gutenberg-faq\" style=\"background:#f6f7f7\"><div class=\"question\" style=\"background:none;color:#000\"><h4 style=\"color:#000\">What does a louse look like?<\/h4><\/div><div class=\"answer\" style=\"background:none;color:#000\">A head louse is a small parasitic insect visible to the naked eye. It measures between 2 and 4 mm and has an elongated body with six small legs. It moves quickly through the hair. A live louse is usually found close to the scalp, particularly behind the ears and at the nape of the neck.<\/div><\/div>\n\n\n\n<div class=\"wp-block-faq-block-for-gutenberg-faq\" style=\"background:#f6f7f7\"><div class=\"question\" style=\"background:none;color:#000\"><h4 style=\"color:#000\">How long do nits stay attached?<\/h4><\/div><div class=\"answer\" style=\"background:none;color:#000\">Nits can remain attached to the hair for several weeks, even after hatching.
