The lice are insects that feed on the blood of individuals who infest (called “guests”). Lice infestations are called ” pediculosis “.The species of lice that infest humans are essentially three:

  •       Pediculus humanus corporis(body or clothing louse).
  •       Pediculus humanus capitis(scalp or head louse).
  •       The Phthirus pubis(pubic louse, also commonly known as “lizard”).

Why do Lice come?

Many mothers wonder where these annoying parasites are born, or where they come from; the answer is invariably one, from the contagion by another subject who is affected.

Lice can NOT be generated out of anywhere due to poor hygiene or otherwise, but transmission can also take place by indirect contact through the exchange of clothing or personal effects (scarves, hats, jackets). Children are mainly affected by their ways of interacting, in simpler words, because they spend a lot of time in the community (school and kindergartens) in close contact with each other (playing, studying, eating).

The data relating to the spread of the infestation worldwide say that between 6 and 12 million children between 4 and 11 years of age are affected each year. They propagate only by direct contact (lice do not fly from one head to another!) And can affect anyone, regardless of age and degree of hygiene. It is essential to dispel the myth that pediculosis is an indication of poor cleaning. In fact, it seems that the dirtiest hair, that is, with a greater quantity of sebum on its surface, can even make the adhesion of the parasite more difficult.

It is also impossible to be infested with animal lice, such as dog lice, for example, as the infestation is species-specific (each species has its own lice).

Some Effective Homemade DIY Lotions for Lice Treatment:

  •       Vinegar lotion– With vinegar, you can also prepare a lotion with white wine, in equal parts, and then pour it after washing your hair. Distribute all the hair well and then wrap the hair in a plastic bag for about 10 minutes. Finally, rinse with water, and you’re done.
  •       Vinegar and mayonnaise– Take a portion of vinegar and two of mayonnaise and mix them in a bowl: thus prepare an excellent mixture for this problem. Moisten the mixture over the hair and scalp, cover them properly, and leave for 2 hours. Then rinse with lukewarm water and detangle the hair with the lice comb. Once a week, rinse children’s hair with a glass of vinegar: it is able to purify the section of the hair to which the nits are attached.

Neem oil is, in fact, a real cure for the hair. In addition to leaving the hair shiny and bright, as it is very nourishing, it protects it.

However, it suffocates the lice and can easily be extracted by using it. Lice can be removed in this treatment by using it again and again.

Essential oils are usually mixed with cleansing oils, lotions, and fixing gels. There are many products based on vegetable oils (bergamot, tea tree, thyme, lavender, anise, coconut, ylang-ylang) capable of combating pediculosis. Essential oils induce a respiratory crisis in the parasite and suffocate it. Furthermore, they kill the nits, preventing a possible spread.

The treatments based on these oils are easy to follow and, unless you are allergic to one or more of the contents, the risk of adverse and undesirable effects is practically zero.

Top drugs used for the treatment of lice:

The medications that are used to treat lice are pesticides and insecticides. These drugs are available in the form of lotions, gels, creams, foams, or shampoos to be applied to the area affected by the infestation. To prevent the onset of new infestations, the use of drugs is not enough. In fact, it is necessary to wash all clothes, towels, and sheets at high temperatures (not below 60 ° C), using a normal detergent, sodium perborate, or pyrethroid-based products.

However, the use of the comb alone is not effective in completely eliminating the infestation. Therefore it must be accompanied by adequate therapy with antiparasitic drugs or insecticides. The following are the drugs most commonly used in head lice therapy (both head, pubic, and body). It is up to the doctor to choose the most suitable active ingredient and dosage for the infested person, based on the severity of the disease, the patient’s state of health, and his response to treatment.

These are Synthetic pyrethroids:

What Are Pyrethroids:

Pyrethroids are molecules of synthetic origin having a chemical structure similar to that of pyrethrum, a natural insecticide that is extracted from some plants belonging to the Asteraceae family. These drugs are available in the form of shampoo, skin foam, powder, gel, skin emulsion, and lotion.

Among the most used pyrethroids, we find:

1.Permethrin And Lice:

Permethrin is easily available in different formulations (shampoo, skin emulsion). When permethrin is used as a skin emulsion, it is recommended to apply it on the scalp and damp hair for about 10 minutes, after which the hair must be thoroughly rinsed and dried. In most of the cases, only one treatment is sufficient to eliminate lice and eggs. In addition, permethrin sprays are also available, which can be used on clothing and fabrics just before washing in the washing machine.

2.D-phenothrin For Lice:

It is also available in different formulations (shampoo and gel). When using the D-phenothrin-based shampoo, it is recommended to apply about 30 grams of the product on damp hair and to massage and rub the scalp for 3-5 minutes, after which it must be rinsed carefully, and the operation repeated a second time. Generally, a single treatment is enough to end the infestation, but for preventive purposes, the treatment can be repeated after a few days. In addition, D-phenothrin is also available in combination with tetramethrin (another synthetic pyrethroid) in the form of shampoo or powder.

3.Lice and Bioallethrin:

Bioallethrin is available in the form of shampoo and lotion. The product must be applied to the hair, left to act for a few minutes, and then properly rinsed.

Other Lice Medications:

1.Malathion and Lice:

Malathion is a highly effective organophosphate insecticide that has low toxicity to humans, which is why it is widely used in the treatment of head and pubic lice. The Malathion causes respiratory paralysis of the louse. It is mostly found in the form of gel or shampoo. When using the gel formulation, it is recommended to apply the product on dry hair or hair with the help of a comb and leave on for ten minutes. Then you can rinse and eliminate dead eggs and insects with the use of a fine-tooth comb.

2.Ivermectin For Lice:

It’s a broad-spectrum antiparasitic drug, used both in humans and in the veterinary field. For the treatment of lice, ivermectin is available in tablets for oral administration, or in the form of a lotion for cutaneous use which must be applied on dry hair for about ten minutes. Ivermectin, however, is not a first choice lice drug. Its use, in fact, must be reserved for the treatment of, particularly invasive infestations or which do not respond to other treatments.

3.Dimethicone for Lice Treatment:

Dimethicone derived from silicone and known for its anti- meteoric properties must be applied to the scalp and for the entire length of the hair. By covering the louse completely, it favours its elimination by suffocation. The latter active ingredient has been introduced relatively recently and, being well tolerated and free of important side effects, it is indicated for young children (after 6 months of age) and pregnant women.

The same principle of action is shared by other substances such as dimethiconol, sodium bicarbonate, and silicon dioxide. But now, let’s take a closer look at the three categories of active ingredients previously mentioned, which are the basis of most of the products on the market for the treatment of lice.

Traditional drugs:

The life cycle of the louse is about 1 month and develops in 3 phases:

  • The phase of the eggs (or more correctly nits),
  • The phase of the nymphs
  • And finally, the adult stage.

When the presence of lice or nits is detected, adequate therapy should be immediately initiated. Most anti-pediculosis drugs are marketed as para-pharmaceutical or over-the-counter (OTC) preparations, therefore without prescription. Almost all the products available are active on all three forms of the parasite, but since the nits sometimes survive the treatment, it is essential to proceed with a second application of the chosen product 7-10 days after the first, so as to hit any nymphs first of laying new eggs.

Oral products:

If lice infestations prove to be very resistant, the doctor may decide to prescribe oral products. One of the two most used products is an antibiotic, sulfamethoxazole + trimethoprim (Bactrim). Once ingested by the parasite through the blood circuit, it kills the bacterial flora in the gastrointestinal level, causing the death of the louse due to a vitamin B deficiency.

This product is almost always tolerated even if allergic reactions have been reported in predisposed subjects.

Natural products:

Lice are generally eradicated if proper treatment is performed; however, in some settings such as a school with many infected children, it is not uncommon to observe repeated infestations. When a case is found in a family or school or children’s centre, each child should be examined. This can help prevent further spread.


Some subjects will develop a secondary infection of the skin due to scratches: in these cases, antihistamines prescribed by the doctor can help to relieve the itching if necessary, and any local antibiotic treatment will lead to the resolution of the infection.

When to contact a doctor:

Call your family doctor if symptoms continue after treatment at home, or if you experience inflamed and fragile skin, a sign of a possible infection.


There are many effective ways to treat lice, but you should try these according to your skin condition and the complication of your case. So you have to consult to a doctor in any critical condition. If you have sensitive skin, any kind of chemical can harm you or your skin badly. The use of oils is effective in this situation. In the opposite situation, you may use chemicals on your skin or use some oral products. But I again advise you to consult to doctor or use these medications according to the doctor’s prescription.
