What are Demodex hair mites? These tiny living things (or bugs) are usually found in our hair follicles and can cause our scalp to become itchy. They are microscopic and as a whole, they are referred to as “Demodex”. Scientists have found that there are at least one of two species present in many adults.
Some common bugs that can be mistaken for lice are ants, bedbugs, and fleas. A few things all these bugs have in common is they're small in size, can be dark colored, and can give you an itchy head. A few things that can be mistaken for lice nits are dandruff, hair product, or dirt.
Up to 10 million organisms of the yeast-like fungus Malassezia globosa live on an average person's head, according to a 2007 Procter and Gamble study published in Proceedings of the National Academy of Sciences. “Malassezia globosa is found on everyone's scalp,” says P&G Principal Scientist Dr.
The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. Head lice are wingless insects that spend their entire lives on the human scalp and feeding exclusively on human blood.
Head lice and the human hair
The head louse (Pediculus humanus capitis) is an insect parasite, spending its entire life on human hair and feeding exclusively on blood, 4-5 times daily. Man is the only known host of this parasite.
Infections are generally treated with anti-parasitic drugs in combination with anti-inflammatory drugs. Surgery is sometimes necessary to treat cysts in certain locations, when patients are not responsive to drug treatment, or to reduce brain swelling.
Horsehair worms are slender (1/25 to 1/8 inch wide), very long (4 to 24 inches), and yellowish-tan to brownish-black in color. They often squirm and twist, knotting themselves into a loose, ball-like shape, resembling the so called "gordian knot," in freshwater pools.
Ringworm of the scalp (tinea capitis) is a rash caused by a fungal infection. It usually causes itchy, scaly, bald patches on the head. Ringworm gets its name because of its circular appearance.
The most common treatment of Demodex infestations is metronidazole. Topical metronidazole administered in combination with azelaic acid and oral doxycycline is effective for treating moderate to severe rosacea, which is another cutaneous disease associated with Demodex infestation.
Formication is also a type of paresthesia which is defined as tingling dermal sensations. Causes of crawling sensations on the scalp include delusional infestations, hallucination, substance abuse, a parasitic infestation, side effects from medication, or issues with the neurologic system.
Bumps on your scalp can be a symptom of a few different health conditions. Most of the time, these bumps indicate an allergic reaction or clogged hair follicles, neither of which is usually a cause for concern.
Head lice are tiny, crawling insects that live in the hair on a person's head. The lice feed on blood sucked from your scalp and lay eggs (called nits) that firmly attach to the hair exposed at your skin's surface (hair shafts). An infestation of head lice is pediculosis.
It's not uncommon to find nits in your hair without live lice. If you find only nits, you should still treat your hair as if you have lice. You should also avoid close contact with other people and sharing hats or brushes until you no longer see nits or lice in your hair.
No, dust mites don't live in human hair.
Bedbugs feed off human or animal blood. They're often found in places like the seams of your mattress or cracks in your bed frame. Bedbugs aren't adapted to live in your hair, but it's possible a bedbug could end up in your hair after biting your scalp. Finding bugs in your hair is much more likely a sign of head lice.
Lice and other crawling parasites appear as tiny, slow moving crawlers on the hair and scalp. The result of infestation is a papular rash with extreme itching.
There are two medications that can be used to treat the infection and manage the symptoms. The treatment of choice is diethylcarbamazine (DEC), which kills the microfilariae and adult worms. Albendazole is sometimes used in patients who are not cured with multiple DEC treatments.
What can cause sores or scabs on the scalp? Sores or scabs on the scalp are often harmless and clear up on their own. However, they can sometimes be a sign of a condition that may require treatment, such as psoriasis, contact dermatitis, or head lice.
The 2 most widely used treatments for scabies are permethrin cream and malathion lotion (brand name Derbac M). Both medications contain insecticides that kill the scabies mite. Permethrin 5% cream is usually recommended as the first treatment. Malathion 0.5% lotion is used if permethrin is ineffective.
Under a microscope, the mite looks slightly transparent and is covered with scales. It has an elongated body with two segments. The first segment has eight legs and a mouth. When you sleep, the mites come out of your skin's pores, mate, then go back into your skin to lay eggs.
A common sign of crusted scabies is widespread crusts on the skin. These crusts tend to be thick, crumble easily when touched, and look grayish in color. Sometimes the crusts appear on one or a few areas of the body such as the scalp, back, or feet.
Fungi called dermatophytes cause ringworm of the scalp. Fungi are organisms that thrive on dead tissue, such as fingernails, hair, and the outer layers of your skin. Dermatophytes prefer warmth and moisture, so they thrive on sweaty skin. Overcrowding and poor hygiene increase the spread of ringworm.
Horsehair worms are harmless to vertebrates, because they can't parasitize people, livestock, pets, or birds. They also don't infect plants. If humans ingest the worms, they may encounter some mild discomfort of the intestinal tract, but infection never occurs.
They are found in water or wet areas, such as in or alongside streams or puddles but they can occur in cisterns, livestock watering troughs or most open outdoor container with water. These harmless, curious creatures writhe slowly, contorting their hair-like bodies into intricate knots.
