Itching: Dandruff and lice both itch. Dandruff tends to itch more when the scalp is dry. People with lice may feel a crawling sensation on their scalp. Lymph nodes: Lice can cause bacterial infections , especially when a person scratches their scalp too hard and causes bleeding.
Like lice, dandruff can be itchy, but it is usually not as intense as the itching caused by lice. The drier the scalp, the more dandruff will usually itch.
Dandruff is not a contagious skin condition, but head lice spread easily from person to person, especially in children or people who are around children often (like teachers, parents, or daycare employees). Rest assured, however, that lice are not known to carry or transmit diseases like other parasites.
Common signs and symptoms of lice include: Intense itching on the scalp, body or in the genital area. A tickling feeling from movement of hair. The presence of lice on your scalp, body, clothing, or pubic or other body hair.
Head lice can cause an itchy scalp, but so can other skin conditions, such as dandruff, eczema, or even allergies to shampoo and other hair products.
An intensely itchy scalp without signs of a rash or another skin reaction can be a sign of a nerve problem. Your doctor may say you have neuropathy (neu-rop-ah-thie). It's the medical word for a problem along a nerve due to damage, disease, or an abnormality in the way the nerve works.
Location: Lice lay eggs called nits while dandruff causes flaky skin. The two look similar, but close inspection reveals key differences. Nits stick to the hair while dandruff flakes, easily falling off of hair. While dandruff is visible on the scalp, lice lay eggs on hair, not the scalp.
Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed. Look for nits near hair follicle about ¼ inch from scalp. Nits (eggs) will be white or yellowish-brown.
Itching. The most common symptom of head lice is itching on the scalp, neck and ears. This is an allergic reaction to louse bites. When a person has head lice for the first time, itching may not occur for 4 to 6 weeks.
Head lice are most active at night. Itching is the first and most common symptom but may not appear for weeks after contracting lice. The itching is caused by an allergic reaction to the bug bites which can cause sores or raw skin on the scalp.
Head lice are parasites that are easy to differentiate from dandruff. And no, they do not like dandruff; they love your blood and so, they feed on it. They do not flourish if the dandruff is co-existing on the scalp. Generally, dandruff does not curb the head lice's growth.
You're more likely to get head lice if you have poor personal hygiene. False. Lice are equal-opportunity bugs, no matter how often you wash your hair or if you have dandruff. They are parasites, so they are attracted to human blood.
Dandruff shampoos like Head & Shoulders work by using the active ingredient, zinc pyrithione. It helps protect your scalp from dandruff-causing oleic acid. It's been proven on dandruff, but does nothing to inhibit lice.
Nits, nymphs, and adult lice: 2 weeks or longer.
If you have symptoms like itching along with a variety of lice stages, you've likely been living with lice for four to six weeks or possibly longer.
Not everyone feels lice moving around on their scalp, but some people do. Dr. Garcia says that most of her patients say they “don't feel anything,” but others may get a creepy, tickling sensation as lice move around their head.
Using your finger to check for and extract nits (eggs, each of which houses a baby louse) is an integral part of a lice check and can be helpful when treating an infestation. You can actually feel the nits stuck to the hair shaft; each one will feel like a bump on the hair.
Permethrin lotion, 1%;
Permethrin lotion 1% is approved by the FDA for the treatment of head lice. Permethrin is safe and effective when used as directed. Permethrin kills live lice but not unhatched eggs. Permethrin may continue to kill newly hatched lice for several days after treatment.
You can check for lice in either wet or dry hair, but we recommend wetting the hair and preferably adding conditioner. The lice do not move as much and they attach more easily to the lice comb (10, 13).
Lice eggs (nits).
These look like tiny yellow, tan, or brown dots before they hatch. Lice lay nits on hair shafts close to the scalp, where the temperature is perfect for keeping warm until they hatch. Nits look a bit like dandruff, but aren't removed by brushing or shaking them off.
Although body lice and nits can be large enough to be seen with the naked eye, sometimes a magnifying lens may be necessary to find lice or nits. Diagnosis should be made by a health care provider if you are unsure about an infestation.
Changes in body temperature: During sleep, natural fluctuations in skin temperature may be associated with increased itch intensity. Hormone fluctuations: At night, your level of anti-inflammatory hormones (corticosteroids) naturally falls, which may exacerbate itchiness.
If the itchiness doesn't go away in a few days and is accompanied by hair loss, pain, sores, or intense itching, see your doctor. An itchy scalp due to a fungal infection, lice, and some other conditions won't go away without medical treatment.
The common braid, a French braid, a fish tail braid, or a crown braid are all excellent hair styles to keep your hair up and out of the way of others. Any braid type that keeps your hair pulled back and contained is perfect for helping to prevent your contact with head lice.
Do not share clothing such as hats, scarves, coats, sports uniforms, hair ribbons, or barrettes. Do not share combs, brushes, or towels. Disinfest combs and brushes used by an infested person by soaking them in hot water (at least 130°F) for 5–10 minutes.
