Little, wingless insects known as head lice can be extremely bothersome when they infest human hair. Regardless of age or cleanliness level, anyone can be impacted by these surprisingly common pests. It can be helpful to know how lice spread and what draws them in order to avoid an infestation.
After entering your hair, lice feed on the blood dripping from your scalp, causing irritation, itching, and even infections. Thankfully, lice and their eggs can be removed with the use of efficient treatments.
This article will explain how lice appear in human hair, explain pediculosis treatment options, and include close-up images of these tiny insects. You can take the required precautions to keep yourself and your loved ones safe by becoming more knowledgeable about these pests.
Pediculosis – what is it?
Pediculosis is a parasitic disease that is characterized by lice living directly on the scalp and the effects of their activity. Which kinds of lice exist?
- head;
- clothes: parasites settle in clothes and bed linen;
- pubic: lice and nits affect the scalp of the groin area.
Because public pediculosis is linked to the activity of a different kind of insect, the public louse, it is a distinct disease. The only difference between the head and body forms of the disease is where they manifest, but they are both caused by the same species of insects—the human louse. Additionally, we will discuss the human head louse in particular; an image of the bug is provided.
The insect’s body is translucent and oblong in shape.
Blood saturating the stomach causes it to gleam bright red through the chitinous coverings. The body measures between one and four millimeters in length.
The only ways to identify this highly mobile and expertly hidden insect from humans are by its symptoms and the presence of laid eggs in the hair.
NOTE: There are species-specific lice. This indicates that every animal species has unique parasite species that are able to live exclusively on that species and do not interact with one another in any way.
Nits, or lice eggs, are white, granular formations. Their hard shell shields their interiors from outside influences, and when the female lays an egg, she secretes a sticky substance that helps them adhere securely to the hair bases. The larva hangs on the hair for a considerable amount of time even after it hatches from the egg. These formations are referred to as dead nits because of their distinct yellowish hue.
A parasite’s life span is 40 days on average. Lice life cycle:
- 5-6 days – nit (egg);
- 6-20 days – larva;
- 20-40 days – adult insect. As soon as the larva becomes an adult insect, active reproduction begins.
Human blood is the only food source for lice. Every two days, at least, each insect must feed; however, under ideal circumstances, lice can consume blood up to four times a day. The insect must create a tiny wound on the skin and inject a substance that stops blood from clotting quickly in order for it to consume blood. This material causes allergic reactions and itching.

Only smooth, rounded surfaces—hair, clothing fabrics—allow insects to move. However, they can also move on other kinds of surfaces, like combs, if needed. Do lice move in a jumping or crawling manner? They can only move by running because their limbs are weak and have little cushioning. They are unable to jump. Lice, however, have a fast running speed. This establishes the transmission routes for them.

When small parasitic insects known as lice settle in human hair and begin to feed on the blood from the scalp, the condition known as pediculosis, or lice infestation, results. This article describes the symptoms to look out for, how lice spread, and how to get rid of them. To gain a better understanding of the appearance of these tiny pests, you can also find photos of lice taken under a microscope.
Spread and reproduction
How do lice look? An insect must come into close contact with an infected surface in order to travel to the head. Putting on hats, using combs, and sleeping on pillows can all result in contact. Since kindergarteners and school-age children typically don’t pay enough attention to personal hygiene, these kinds of contacts are particularly common among them.
It’s thought that unclean hair makes parasites easier to spread. This is untrue. Lice do not consume any other bodily tissues; they are only interested in blood. Insects find a clean head and hair to be equally appealing.
Another explanation for the relationship between infection frequency and uncleanliness is that individuals who live in unsanitary environments are more likely to interact physically and share hygiene products, both of which raise the risk of illness.
There is no solid scientific evidence to support the theory that being anxious increases the risk of infection.
However, stress can also indirectly raise the risk of lice because anxious people tend to perspire more and have weakened immune systems, which attract insects.
Head lice start reproducing as soon as they settle. A female lays two to four eggs every day, with a maximum of 140 eggs laid in a month during her adult life.
It is not difficult to estimate that in a matter of weeks, a head lice colony can expand to such an extent that an individual will find it intolerable to continue their activity with frequent bites. Only a few parasites reside on the head during the early stages of the disease; later on, their numbers can reach tens or even hundreds.
REFERENCE: Only the head’s surface is home to head lice. There are scabies mites, not "subcutaneous lice," which are sometimes mistaken for the agents that cause pediculosis because of their similar appearance and feeding habits.
Symptoms
Pediculosis may not always be accompanied by itching. Lice may go unnoticed if a person who is not prone to allergic reactions has insensitive skin, has lice, and the insects have not had time to multiply. In this instance, they can only be identified by a comprehensive analysis.
If you comb your hair in a bright light and notice nits at the base of your hair, there is a 100% chance that you have pediculosis on your head. Nits are affixed to the entire length of the hair in the later stages of the disease, and they are readily seen from the side to the unaided eye.
A person suffering from allergies or having a lot of insects living in their hair may find it difficult to ignore the symptoms of pediculosis. The condition presents as vexing itching, small but frequent papules, and lymph node inflammation, particularly after numerous insect bites.
LISTEN UP! Since itching is most active at night, insomnia may result. Consistently scratching the skin with unclean hands can allow streptococcus bacteria to colonize, causing abscesses and pain to become apparent.
If lice have appeared – treatment
Skin health is the responsibility of a dermatologist; if you notice any signs of pediculosis, you should see him. It will not be unnecessary to see a trichologist if you have head lice.
How can head lice be removed? There are two approaches to treating head lice: mechanical and pharmaceutical. Both approaches interact complexly in full-fledged therapy.
For the purpose of forcing the lice to leave the host’s body, mechanical treatment involves shaving all hair or drastically cutting it short.
If this option is not acceptable, then the hair is carefully combed using metal combs that have flat, frequent teeth.
The preparations’ form factors also differ: lotions, anti-pediculosis shampoos, lice and nit sprays, special ointments (like sulfuric and benzoyl benzoate), etc. Medicinal hair treatment entails applying products that either eliminate or deter parasites. These include industrial pesticides like DDT, dichlorvos, kerosene, hairspray, and hair dye, as well as medicinal ones like permethrin and malathion. Industrial pesticides are not advised for the treatment of pediculosis, particularly in children, pregnant women, or nursing mothers, as they have not undergone human clinical trials.
Products based on insecticides:
- parasidosis;
- hygia;
- full marks;
- dust soap;
- hemerichnaya water.
Mineral oils are also used to make medications. Certain oils, like clearol, have the ability to envelop insects, suffocating them with a film. Although this is safe for humans to use, it is not very effective when nits are present or the disease is advanced. The scent of certain essential oils, like tea tree and ylang-ylang, keeps parasites away. Although applying them is a good preventive measure, they are ineffective in treating hair that has already become infected.
Products made of oil:
- liceGuard;
- paranit;
- nuda;
- pedikulen Ultra;
- oil masks and lotions, prepared independently.
You will learn the temperature at which a louse perishes thanks to our article on using hair straighteners to treat lice and nits. Medical experience demonstrates that pediculosis does not go away on its own in the absence of therapy. There is no reason for the insects to leave the host as long as they are content to live there and are not in danger.
The spread of parasites can only lead to the disease’s further progression. If proactive steps are not taken to address pediculosis, the skin condition may worsen and cause complications.
The hair will start to look really ugly, and dead nits and corpses will hang on it all the time.
Prevention
The key to preventing the illness is practicing good personal hygiene. Wearing other people’s hats and using other people’s combs is not advised. Hair is treated with insect repellents when visiting unfavorable locations. Routine head exams are performed during epidemiological times when infection risk is elevated. When kids go to kindergartens and schools in the fall and spring, special attention is paid to the state of their hair.

| Cause of lice in hair | Treatment for pediculosis |
| Lice spread through close contact with an infected person or by sharing personal items like combs, hats, or bedding. | Use medicated shampoos or lotions designed to kill lice. Follow the instructions carefully, and repeat the treatment if needed. |
| Lice can also be transmitted in crowded places like schools or public transportation. | Comb out nits (lice eggs) from hair with a fine-toothed comb after treatment to ensure all lice are removed. |
| Photos of lice under a microscope show their tiny, wingless bodies and claw-like legs, designed for gripping hair strands. | Wash clothing, bedding, and personal items in hot water to prevent reinfestation. |
Although dealing with head lice can be annoying, it can be made easier by knowing how they spread and using the appropriate treatments. You can effectively treat and prevent pediculosis by acting quickly and adhering to the recommended steps.
Since lice spread quickly, it’s also critical to check and treat every member of the family if any are found. Reinfestation can be avoided by routinely cleaning personal items, clothing, and bedding.
Even though it may be unsettling to see lice under a microscope, this common problem can be effectively managed and resolved with the right approach.
