What types of parasites are in humans?

A parasite is an organism adapted to adverse conditions that can live in any part of the human body. Compiled a special treatment for parasites in the hair, in case the parasites live on the head. Also, these creatures live in all internal organs, on the scalp and under the skin. This article will focus on the types, symptoms, treatment and prevention of parasites in the human head.

Types of hair parasites and symptoms

types of parasites in the body

There are entire classes of organisms that parasitize human hair. Its nutritional component is human tissue, that is, skin, sebum, blood. By feeding on the tissues, the parasites make themselves felt by the appearance of itching, pain in the scalp, hair loss and the creation of significant discomfort. Such parasites are difficult to miss, they are extremely dangerous to human health.


Every parent and every child knows about head lice, or in other words, lice. The main risk group is school-age children. The main danger of lice is invisibility to the naked eye. They look like tiny critters that are able to disguise themselves under the light skin of the human head, due to the pale color of the body. Nits are lice eggs that adhere tightly to the roots of the hair, making them often difficult to remove. Nits contain larvae. Lice are capable of running rapidly, transmitted by direct contact from people, that is, by touching the head, with hats or clothes. The bites are left behind and are more comfortable on the temples and the back of a person's head.

The flea is an omnivorous parasite

The flea was a former carrier of plague and typhus. Most of the time it inhabits animal skins, but it also occurs in humans. These are insects of different shades, from yellowish to dark brown. Fleas are classified according to the type of host. They are divided into the following types:

  • Home: underwear; genital.
  • Others: dogs; feline; chicken; human; rat; earthen.

Human fleas are versatile. They can feed on human, dog or cat blood. In addition, there are species that choose their habitat in the form of rugs, upholstered furniture. These fleas are called house fleas. Ground fleas live in the garden, they do not pose a danger to humans, because they do not feed on blood. The main danger of fleas is that they carry infectious diseases.

Parasites under the scalp

Subcutaneous parasites are common in hot, tropical countries. Getting rid of them takes much more time and effort than those that live on the surface of the skin. Under the scalp, wrists, armpits, spaces between the fingers, a microscopic scabies mite parasitizes, causing scabies disease. It feeds on the tissues of human skin, gnawing paths under the skin and causing excruciating itchiness. Another dangerous subcutaneous pest is heartworm. This parasite develops under the mucous membrane of the eye, which can damage vision or even blind a person. It is possible to get rid of it only by surgery.

Hair mites

A hair mite or demodex lives in human hair and eyelashes. Harmful to the scalp and hair structure, it causes excessive hair loss. At first, they feed on dry scales, pieces of dead skin, then they enter the follicles and cause serious damage, as a result of which the hair falls out. A mite on the eyelashes causes the formation of white or yellowish scales between the hairs, as well as their fall. This parasite often causes bright red acne on the face. For a long time, you may not remember yourself, but when immunity weakens, it makes itself felt by the above reactions.

The reasons for the appearance of parasites in the human head

Each type of parasite enters the human body from the external environment. Lice are transmitted directly from person to person or through the things of the infected. Fleas are brought into the home by pets, transmitted from one animal to another, and also from one animal to another person and vice versa. Subcutaneous parasites enter the human body along with raw water, as a result of swimming in contaminated bodies of water, from animals, as well as through direct contact between people. Demodex lives in the human body, without causing any discomfort or harm, but in case of deterioration in the quality of skin care, hair, the use of aggressive cosmetics, it activates and causes the extremely unpleasant symptoms described above.

Intruder cure

Lice Treatment

Each type of parasite that lives in the human head requires a specific treatment. Head lice is usually treated at home. Use the drugs intended for this, which can be in the form of a spray, shampoo, cream, emulsion. In order to choose a suitable remedy from the variety presented in stores and pharmacies, you need to pay attention to the composition of the drug.

Get rid of fleas

The flea is a fickle inhabitant of the human body. She is in constant motion. The parasite, having drunk blood, leaves the body until it becomes hungry again and begins to search for a new victim. Therefore, a more or less permanent habitat of this parasite is the room or the hair of the animals. For treating a pet, there are many medications that are sold in pet stores. And to get rid of fleas indoors, they use different methods of disinfection. They do the cleaning themselves by buying a special tool, or request this service at the appropriate service. Also, it is worth remembering that if fleas are found on an animal, you need to make sure that they have already deposited the larvae in different parts of the house. Therefore, treating the animal alone is not enough. In general, the disinfection of the premises is combined with the treatment of the hair of the animals.

Expulsion of subcutaneous parasites

Compared to skin parasites, parasites under the skin are a much greater nuisance, if not a danger to human health. Treating hair for parasites that live under the skin takes a lot of time and effort. This type is difficult in terms of diagnosis, since the symptoms are often falsely perceived as diseases of the internal organs. Most of the time, they are removed surgically, but some of them, for example, the scabies mite, are removed with the help of ointments, solutions and other medications.

Demodex Therapy

Demodex lives harmlessly in the human body until external conditions cause its active nutrition and rapid development. The treatment requires a lot of time, effort and systematization. To cope with this problem, your own efforts are not enough - you cannot do without an experienced dermatologist. After making sure that the symptoms indicate demodex, it is worth stocking up on:

  • drugs prescribed by a doctor (such as preparations with the addition of sulfur, tar, zinc and mercury ointments);
  • antifungal ointments;
  • anti-inflammatory ointments;
  • vitamins.

Be careful with demodex drugs! As a general rule, these funds are quite toxic. Therefore, they are contraindicated in pregnancy, lactation, kidney and liver diseases.


Like treatment, each disease has its own preventive measures. To warn a child against the disease of lice, it is worth teaching him to use only his comb, hats, and not to allow other children to take personal hygiene products. In public places (in cafes, schools, circles), we recommend hanging your outerwear on a common hanger, after turning it over.

For the prevention of fleas in animals, special anti-flea collars for dogs and cats are used. Bathe pets with preventative shampoos. When it comes to indoor flea prevention, just keep your house clean. In order not to face the problem of parasites under the skin, you should not drink unboiled water, swim in stagnant bodies of water (especially in countries with hot climates) and eat raw meat. And Demodex, as already mentioned, will not create problems if you follow the rules of hair and skin hygiene, using appropriate cosmetics.

Nutrients that come with food are poorly absorbed or not absorbed at all. Fat enters the large intestine instead of the small intestine. This causes cramps, excess gas, and bloating.
