How to spot lice and nits: signs and symptoms
Detecting lice and nits on a person is an important step for timely initiation of treatment and preventing their spread. Lice are parasitic insects that feed on human blood and can cause serious discomfort and irritation.
Nits are lice eggs that attach to the hair and are the first stage in their development. To successfully combat these parasites, you need to know the main signs and symptoms of their presence. You can find out more about the fight against lice on the blog.
Signs presence of lice and nits
1. Itching and irritation of the scalpOne of the first and most common signs of lice is severe itching of the scalp. This itching is caused by lice saliva that gets onto the skin when bitten. Lice saliva contains substances that prevent blood clotting, which allows the insects to feed easily. As a result, the skin begins to itch, which leads to intense scratching. Itching is especially common on the back of the head, behind the ears and on the temples, where the skin is most sensitive.
2. The appearance of redness and rashes.Scratching the skin can lead to the appearance of small wounds, redness and rashes. These skin lesions create favorable conditions for secondary infections, which can complicate treatment. Small bumps may form at the sites of lice bites, which look like bites from mosquitoes or other insects.
3. Visible nits on hairNits are small lice eggs that initially appear as small, oval-shaped structures firmly attached to the hair. They have a yellowish or whitish tint and can be easily confused with dandruff. However, unlike dandruff, nits are very difficult to remove from hair, as they are glued to it with a special sticky substance secreted by the female louse. Nits are usually located at a distance of 1-2 centimeters from the roots of the hair, since it is in this area that their best development occurs.
4. Presence of adult liceAdult lice may be visible on the hair and scalp upon close inspection. They are about 2-3 millimeters long and can be seen with the naked eye. Lice are grayish or brown in color, which can vary depending on how recently they have fed on blood. Most often they can be found on the back of the head and behind the ears, where they prefer to be.
Symptoms of lice and nits infestation
1. Trouble sleepingIntense itching from lice bites can cause trouble sleeping, especially in children. They may become restless and have difficulty sleeping.
2. Nervousness and irritabilityConstant itching and discomfort can lead to nervousness and irritability. Children can become moody and adults can become anxious.
3. Flaky and dry skinScratching can cause damage to the scalp, flaking and dryness, which creates the illusion of dandruff. With lice, this is accompanied by intense itching.
4. Enlarged lymph nodes.Severe infestation can lead to enlarged lymph nodes in the neck and back of the head, which requires consultation with a doctor.
How to detect lice and nits
1 . Using a fine-tooth combA fine-tooth comb is effective in identifying and removing lice and nits. First wet your hair, then comb it thoroughly from roots to ends. After each pass, check the comb for parasites.
2. Inspect in good light.Inspect your scalp and hair in bright light. Nits and lice are small and may be difficult to see in low light. Pay special attention to the areas behind the ears and on the back of the head, where lice often lay eggs.
3. Contact a specialistIf self-examination does not produce results, consult a doctor. A specialist will help you accurately determine the presence of lice and nits and suggest appropriate treatment.
