Invasive organism such as parasites and fungi can cause hair loss. Both of these survive on the same food that you eat. This means that if you are infected with one of these organisms your body could lose nutrients and become undernourished.
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.
Seizures and headaches are the most common symptoms. However, confusion, lack of attention to people and surroundings, difficulty with balance, excess fluid around the brain (called hydrocephalus) may also occur.
Scalp pediculosis
Topical pediculicides remain the main treatment. Permethrin shampoo 1% should be left on the scalp for 10 min and then rinsed. Piperonyl butoxide 15% may also be used as shampoo. Permethrin 5% may also be used, applied to the scalp at night, and removed the next day.
Pediculosis is a common condition with a worldwide distribution [56,57]. Patients usually refer intense pruritus of the scalp due to an allergic reaction to the saliva that the parasite produces. Scalp itch takes around 4-6 weeks to manifest if it is the first infestation [58].
Pediculosis capitis is the most common worldwide infestation of the scalp.
The most common symptoms of scabies, itching and a skin rash, are caused by sensitization (a type of “allergic” reaction) to the proteins and feces of the parasite. Severe itching (pruritus), especially at night, is the earliest and most common symptom of scabies.
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.

Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
Gastrointestinal distress — since parasites take up residence in the intestines, this is where the most damage occurs. Diarrhea, constipation, gas, bloating, and nausea are all common symptoms of parasites. Weight loss — parasites can cause nausea and poor nutritional absorption, which can lead to weight loss.
The diagnosis of neurocysticercosis usually requires MRI or CT brain scans. Blood tests may be useful to help diagnose an infection, but they may not always be positive in light infections. If you have been diagnosed with cysticercosis, you and your family members should be tested for intestinal tapeworm infection.
Demodex folliculorum and Demodex brevis are two species of tiny parasitic mites that live in the hair follicles and sebaceous glands of human skin, respectively.
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.
Demodex, a genus of tiny parasitic mites that live in or near hair follicles of mammals, are among the smallest of arthropods with two species Demodex folliculorum and Demodex brevis typically found on humans. Infestation with Demodex is common; prevalence in healthy adults varying between 23-100%.
The most common treatment of Demodex infestations is metronidazole.
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.
The oral antifungal griseofulvin is one of the most commonly used medications to treat fungal infections of the scalp. To properly treat the infection, you may need to use griseofulvin or another medication for four to eight weeks. Itraconazole, fluconazole, and other medications are also used to treat scalp fungus.
A stool ova and parasite, or O&P, test is a simple way of diagnosing parasite infections. This test determines whether parasites and their eggs are present in your stool. The stool O&P test is a common way to find out if you have parasites in your digestive tract.
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.
While folliculorum tend to stay on the face, D. brevis can distribute all over the body. The chest and neck are common areas of D. brevis infestation, so you might notice more symptoms there if you have it.
Causes. Fungi are germs that can live on the dead tissue of the hair, nails, and outer skin layers. Ringworm of the scalp is caused by mold-like fungi called dermatophytes. The fungi grow well in warm, moist areas.
Signs of the skin inflammation. The condition can lead to flakiness, redness, dandruff and other scalp buildup — and sometimes it's sign of other conditions. Flaky scalp, itchiness and painful patches can all be signs of scalp dermatitis, an inflammation of the scalp that can have as many causes as it does symptoms.
