Head lice are a problem for children and adults alike, but this condition is easily spread by sharing personal items. This can occur through head-to-head contact and sharing of clothing. The best way to prevent getting head lice is to wash your clothing regularly. You should also keep your personal items out of shared areas.
The most common symptoms of head lice include intense itching. If the infection is severe, the infested person may also experience itchiness in other parts of the body. This can occur around the hairline and at the waist and upper thighs. The itchiness can also occur in the genital area. You should avoid scratching the affected area because prolonged scratching can lead to sores and infections.
Head lice are difficult to eradicate. If you think you have head lice, you should treat it immediately. Your scalp will become itchy for two to three weeks. You should also inspect your clothing and bedding. The lice in your head may not be visible with the naked eye, so you may need a magnifying glass to see them. If you don’t treat your head lice infestation, you could develop an allergic reaction to the lice and even become dehydrated.
Adult head lice are tiny, grayish-white insects that feed on human blood. They hatch from an egg called a nit. The nymph feeds on your scalp several times a day and matures into an adult head louse after 9 to 12 days.
