Lice are small parasites that feed on the blood of their hosts. They can range in size from 1. 3mm to 2. 6mm in length, are tan or brown in color, and have six legs with claws for grasping onto hair shafts.
Their head is smaller than their abdomen, and has a thin arched antennae. Most types of lice have a three-segmented body, wings and eyes. The abdomen has small red, brown or black spots that are vestigial air sacs used to absorb oxygen.
Some species can be darker in color such as black lice. Female lice are usually larger than males, and they lay tiny white eggs, known as nits, which are firmly attached to hair shafts near the scalp.
After hatching, lice will mature in 7 days and can live for up to 30 days.

How do you know if you have lice?
If you suspect you may have lice, the most reliable way to confirm is to have a trained health professional examine your hair and scalp. Common signs of lice include intense itching of the scalp and neck, small white dots (eggs) on the hair shaft, and live lice running around in the hair or along the scalp.
You may also notice sores on the scalp as a result of scratching. In some cases, live lice may be seen moving around on people’s clothing or on their pillows and bed linens. If you suspect someone in your household has lice, it is important to inform public health officials and screen everyone in the household.
Treatment may be necessary to prevent the spread of lice. Treatments may include over-the-counter and prescription products, as well as special combs or climate manipulation. Your healthcare provider can advise you on the best way to treat lice and prevent re-infestation.
How do I check myself for lice?
To check yourself for lice, start by examining your scalp carefully with a fine-toothed comb or a lice comb. Work slowly, making sure to move slowly over all areas of your head, especially around the nape of your neck and behind the ears.
Part your hair in 1” sections and look at the base of the scalp, the nape of the neck, the back of the ears, and wherever else you can see. Any specs found could likely be lice eggs, also known as nits, which are oval shaped and yellow to white in color.
If you find anything that looks like lice, feel free to call your doctor for further direction. In the meantime, remain calm and keep any items you think may contain lice in a sealed plastic bag or discard of them.
You will also want to make sure to change your clothes and wash them in hot water to make sure to clean any potential lice that may have been on them. After you change clothes and wash them, dry them on the hot cycle in a dryer.
Stage two of checking for lice is to also monitor the entire family for any signs of lice. Examine everyone close to you who has been in contact with the infested person. If you find any nits or adult lice on anyone, there is a good chance that the lice have spread and could have spread to other family members as well.
To prevent the lice from spreading, make sure to keep yourself away from anyone infested and keep your hair neat and it’s possible to buy lice repellent products that will help keep away any lice or eggs.
What is one of the first signs of head lice?
One of the first signs of head lice is itching on the scalp, neck, and behind the ears. This is caused by an allergic reaction to the saliva of the lice. Other signs of head lice include small red bumps on the scalp, irritability, difficulty sleeping, and scalp sores caused by scratching.
Additionally, you may notice small bugs that look like sesame seeds or grayish-white specks in the hair. These are actually lice eggs, known as nits. To confirm a lice infestation, part the hair into sections and thoroughly check the scalp.
If you spot any lice or nits, you should contact your doctor or pharmacist to discuss treatment options.
Can you feel lice in your hair?
It is possible to feel lice in your hair, although it may not be very likely. Lice are small, wingless insects that feed off of human blood. They often move quickly and make their homes in the hair and scalp, although they can also be found in clothing and furniture.

If you do feel lice in your hair, you should seek treatment to prevent further transmission and rid your scalp of them.
What are 4 symptoms of head lice?
Four common symptoms of head lice include itching, irritation, visible lice, and visible nits (lice eggs).
Itching is caused by an allergic reaction to the lice saliva when they feed on the scalp. The itching is usually the worst behind the ears and at the nape of the neck.
Irritation is characterized by red bumps or sores on the scalp, neck, and shoulders when a person scratches the itching frequently. These bumps are often extremely itchy and can become very painful if left untreated.
Visible lice are gray-white in color and are approximately the size of a sesame seed. They move quickly, as they cling to the hair shaft and scalp.
Visible nits are 1mm in size and shaped like a teardrop. Found close to the scalp (within 1/4 inch), they are light tan to gray-white in color and the female louse adheres them to the hair shaft. They are the louse eggs and are difficult to remove as they are very firmly attached.
Do I have lice or am I paranoid?
The best way to decide whether or not you have lice is to talk to a doctor or health care professional. You can also check yourself, but please do not diagnose yourself if you are not sure.
Looking for lice is no easy task! The adult form of lice is about the size of a sesame seed, and is brown or gray in color. The eggs, or nits, are white, yellow, or tan and cling to the hair shaft. A common sign of lice is a tickling or crawling feeling on the head and scalp.
If you think you may have lice, it is best to contact your doctor or health care professional to get a proper diagnosis. If you find lice or nits, please contact your doctor or health care provider right away so that you can receive the appropriate treatment.
Is it hard to tell if you have lice?
It is not always easy to tell if you have lice, as the lice can be difficult to spot. In some cases, lice can be seen on the scalp, but in other cases they can be more difficult to detect. Signs that you may have lice include itching and tickling of the scalp, as well as feeling a clumping of hairs on the scalp.
If you have lice, you may also notice small red bumps, tiny white eggs on the hair shaft, and irritated or scaly scalp. You may also look for lice on clothing, bedding, furniture, or hair brushes. If you are unsure if you have lice, you should visit your doctor or healthcare provider for diagnosis and treatment.
How do you check for lice with a comb?
Checking for lice with a comb is a fairly straightforward process. The first step is to wet the hair with conditioner or a dedicated lice-repelling product. This helps to ease the combing process, as well as suffocate any lice present.
Starting at the nape of the neck, part off small sections of the wet hair and use the teeth of a fine-toothed lice comb to brush through it several times. To make sure to catch any crawling lice, draw the comb through the section in several directions.
Move up the head, parting and combing a new section every time. Check the comb after each pass for lice or small white eggs, called “nits”. If lice or nits are found, continue combing the same section of hair until none can be seen.
Repeat this process until the whole head has been combed thoroughly. If lice or nits are not found after one thorough session, wait a few days and comb again. If head lice are still suspected, consult a doctor.
Are head lice visible to the eye?
Yes, head lice are visible to the eye. They are tiny insects, usually 2-3 millimetres in length, that live on the scalp and feed off the blood of their human host. The most common sign of having head lice is itching of the scalp, however the lice themselves can be seen with the naked eye.
They appear as small, tan-coloured specks that can be seen moving around the head and in the hair. Although lice can be hard to spot, if you part the hair and look closely you should be able to see them.
It can also help to look in bright light, such as natural sunlight or a bright lamp, as this increases visibility.
What can be mistaken for head lice?
Head lice can often be mistaken for dandruff, carpet or clothing fibers, or other debris in one’s hair. It’s important to look closely to determine the difference and ensure that it’s actually lice being dealt with.
Head lice are small, off-white insects that measure approximately two to three millimeters long and are distinguished by two antennae, six legs, and a small flat body. The eggs of lice, or nits, are very small, approximately the size of a sesame seed, and can appear a creamy yellow or brown.
They are normally located within one-quarter inch of the scalp and firmly glued to the hair strand. Dandruff, on the other hand, is a result of a dry scalp and can easily be flaked off. Clothing and carpet fibers, as well as other debris, are even easier to remove and are generally exactly what they look like.
To further distinguish lice from dandruff and these other substances, lice can often be observed moving through one’s hair and their eggs can’t simply be flicked away. Therefore, it’s important to differentiate the differences between these common offenders and head lice to ensure the correct treatment is being administered.
How long can you have lice before noticing?
The length of time you can have lice before noticing can vary depending on the individual and the type of lice. Some individuals may experience symptoms within 24 hours of becoming infested with lice, whereas other individuals may not experience any symptoms for up to two weeks or longer.
Head lice can live for up to 30 days on the host, and can continue to reproduce for up to two weeks. It is not uncommon for individuals to not notice the presence of lice until there is a large infestation present.
During the first few weeks, head lice will feed from the hair follicles, which can be extremely itchy, leading to the individual scratching their scalp more frequently. If you notice an itching sensation on your scalp, it may be due to lice.
Head lice can be difficult to see with the naked eye and will often be found when scratching the scalp, when combing hair, or when inspecting a close-up view of the scalp. If you suspect you may have lice, you should consult your healthcare provider for appropriate treatment options.
Can you see or feel lice?
Yes, you can see and feel lice. When looking for lice, you may be able to actually see the tiny insects crawling on or near the scalp or on the hair shafts. You may also be able to see their eggs, called nits, which cling onto the hair shafts close to the scalp.
They look like tiny white or yellowish-white dots and are usually found behind the ears and at the nape of the neck. Lice bites may also cause itching and you may be able to feel the tiny, bug-like insects moving on your scalp.
However, not everyone may feel the bites, so looking for lice and their eggs is still the best way to know if they are present.
Why does my head itch but no lice?
Including allergies, eczema, dandruff, contact dermatitis, and psoriasis. Allergies to products used on the hair such as hair dye, shampoo, conditioner, or styling products can cause scalp irritation and itching.
Eczema is an inflammatory skin disorder with red, itchy, and scaly patches of skin on the scalp. Dandruff is usually caused by dry, irritated, or oily skin. It can be aggravated by not washing hair enough, or by hormones, stress, fatigue, or poor nutrition.
Contact dermatitis is an itchy rash caused by contact with a certain material, such as a shampoo or hair spray. Psoriasis is a chronic skin condition with thick patches of itchy red skin, often with silvery scales, caused by an overactive immune system.
