• #2 Head lice and nits

  https://www.nhs.uk/conditions/head-lice-and-nits/

  Head lice can make your head feel itchy. […] The only way to be sure someone has head lice is by finding live lice. […] You can do this by combing their hair with a special fine-toothed comb (detection comb). You can buy these online or at pharmacies. […] Treat head lice as soon as you spot them. You can treat head lice without seeing a GP. […] Check everyone you live with, or have close contact with, and start treating anyone who has head lice on the same day. […] Lice and nits can be removed by wet combing. […] You can buy a special fine-toothed comb (detection comb) online or from pharmacies to remove head lice and nits. […] If wet combing has not worked or is not suitable, you could try a medicated lotion or spray.

  Head lice are usually spread from one person to another through casual contact. Although head lice can be unpleasant, there are effective treatment options available. It is important to find and treat lice quickly to avoid spreading them to others. […] There are several options for getting rid of head lice, including creams and liquids, combing, and oral medicine (pills). It is important to follow directions carefully to be sure that the treatment works. […] A topical insecticide (pediculicide) is a substance, usually a lotion or gel, that is applied to the scalp to kill lice. Available insecticides include: […] Only one insecticide treatment should be used at a time. Follow the manufacturer’s instructions for applying the insecticide carefully. […] Use of a nit comb to remove lice and nits after treatment may help to decrease risk for reinfestation.

  A few live lice may be seen 8 to 12 hours after using an insecticide, and there is no need to immediately reapply the insecticide if they are moving slower than they were prior to treatment. […] Wet-combing is a way to remove lice from the hair with careful and repeated combing. It is a good option for treating very young children or if you want to avoid using insecticides. […] A medicine taken by mouth called ivermectin might be prescribed for people whose lice are resistant to topical insecticide treatment. […] Other products, such as products containing topical dimethicone (a nonpesticide, silicone-based liquid also known as „dimethicone”), are marketed for the treatment of head lice in some regions. […] Studies have examined lotions and other materials (olive oil, butter, mayonnaise, petroleum jelly [Vaseline]) that are applied to the head, and then allowed to dry, with the goal of suffocating lice. However, lice are difficult to suffocate; wet-combing probably works as well and is less messy. […] Because there is no evidence that these treatments are predictably effective, we do not recommend any of these treatments.

• #4 Lice – Diagnosis and treatment – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/lice/diagnosis-treatment/drc-20374404

  A health care provider may diagnose head lice after finding a live young or adult louse in the person’s hair or on the scalp, or after seeing one or more nits on hair shafts found within 1/4 inch (6 millimeters) of the scalp. […] Use drugs that treat lice only as directed. Applying too much can cause red, irritated skin. […] Head lice treatment may involve: […] Shampoos containing permethrin (Nix) are usually the first option used to combat lice. Permethrin is a synthetic version of pyrethrin, which is a chemical compound extracted from the chrysanthemum flower. Permethrin is toxic to lice. Follow the directions closely when using this product. […] A lotion containing ivermectin (Sklice) also is available without a prescription. Ivermectin is toxic to lice. The lotion is approved for use in adults and children age 6 months or older. You can apply it once to dry hair and then rinse with water after 10 minutes.

  Don’t repeat the ivermectin treatment without talking to your health care provider first. Possible side effects include eye irritation or redness, dandruff, dry skin, and a burning sensation at the application site. […] In some locations, lice have grown resistant to the ingredients in nonprescription treatments. If nonprescription treatments don’t work, your health care provider can prescribe shampoos or lotions that contain different ingredients. […] Ivermectin (Stromectol) is available by prescription as a tablet taken by mouth. The oral drug effectively treats lice with two doses, eight days apart. This drug is typically used when other treatments haven’t been effective. […] Malathion is a prescription drug that you apply to the hair and then rub into the hair and scalp. […] Spinosad (Natroba) is a newer prescription treatment for head lice. You can apply it to dry hair and the scalp for 10 minutes and then rinse with water. The treatment doesn’t usually need to be repeated. But it can be used again after seven days if live lice are still present.

• #5 How Head Lice Is Treated

  https://www.verywellhealth.com/head-lice-treatment-2633638

  It can be distressing to discover head lice. However, you can follow some simple steps to effectively treat the lice at home. For particularly stubborn cases, you can check with your healthcare provider to see if you need a prescription. […] This article discusses head lice treatments, including over-the-counter and prescription medication. It also looks at-home remedies and complementary medicine. […] The first-line treatment of head lice is using an anti-lice shampoo, such as Nix or Rid. You can buy these at the drugstore or online. Known as pediculicides, they will kill the adult lice outright, but they don’t kill nits (lice eggs). […] You usually have to re-treat with an anti-lice shampoo seven to 10 days after an initial application. This kills any newly hatched head lice and breaks this lice life cycle. Many experts recommend doing the second head lice treatment on the ninth day.

  Treatment involves a lotion applied to the head of the person and washing of the person’s pillowslip. […] Concentrate on the head. No treatment kills all of the eggs so treatment must involve 2 applications 7 days apart. […] If the insecticide has worked, the lice will be dead within 20 minutes. Treat again in 7 days using the same product to ensure proper treatment. […] If the lice are not dead, the treatment has not worked and the lice may be resistant to the product and all products containing the same active compound. […] Wash off the product and treat as soon as possible using either a product containing a different active compound or the conditioner and comb method. […] Any head lice product can cause a reaction and should be used with care by women who are pregnant or breastfeeding, children less than 12 months old and people with allergies, asthma or open wounds on the scalp.

  https://www.aafp.org/pubs/afp/issues/2019/0515/p635.html

  First-line pharmacologic treatment for pediculosis is permethrin 1% lotion or shampoo. […] Noninsecticidal agents, including dimethicone and isopropyl myristate, show promise in the treatment of pediculosis. […] A no-nit policy is not recommended for schools and day cares because nits alone do not indicate an active infestation. […] Permethrin 1% lotion or shampoo (Nix) is first-line treatment for pediculosis. […] Nonovicidal therapies for pediculosis should be applied twice, seven to 10 days apart, to fully eradicate lice. […] Oral ivermectin (Stromectol) should be reserved for patients with scabies who do not improve with permethrin 5% cream (Elimite). […] Pharmacologic treatment of head lice infestation is focused on three general mechanisms: neurotoxicity resulting in paralysis of the lice (insecticidal treatments), suffocation via coating the lice, or dissolution of the wax covering on the exoskeleton.

• #7 Lice and Scabies: Treatment Update | AAFP

  https://www.aafp.org/pubs/afp/issues/2019/0515/p635.html

  Insecticidal agents that are neurotoxic to lice include permethrin 1% lotion or shampoo (Nix), pyrethrins 0.3%/piperonyl butoxide 4% shampoo (Rid), malathion 0.5% lotion (Ovide), spinosad 0.9% suspension (Natroba), ivermectin 0.5% lotion (Sklice), and oral ivermectin (Stromectol; off-label use). […] Permethrin 1% is recommended as first-line treatment for head lice. […] Noninsecticidal agents that rely on suffocation or exoskeleton dissolution include benzyl alcohol 5% lotion (Ulesfia), dimethicone solution (Nix Ultra, Lice MD), and isopropyl myristate solution (Resultz). […] The Canadian Paediatric Society recommends dimethicone solution and isopropyl myristate solution as second-line agents if permethrin fails after two treatments. […] A key to formulating an effective treatment regimen is recognizing the effectiveness of available treatments in destroying viable eggs because this dictates if retreatment is necessary.

• #7 Lice and Scabies: Treatment Update | AAFP

  https://www.aafp.org/pubs/afp/issues/2019/0515/p635.html

  Malathion, spinosad, and topical ivermectin are considered ovicidal, and they will kill both live lice and eggs in one treatment. […] Treatment of pubic lice is similar to that of head lice. […] The Centers for Disease Control and Prevention recommends permethrin 1% lotion or pyrethrins 0.3%/piperonyl butoxide 4% shampoo as the first-line agent, and malathion 0.5% lotion or oral ivermectin as an alternative. […] Permethrin 5% cream (Elimite) is the first-line treatment for scabies.

• #8 Clinical Care of Head Lice | Lice | CDC

  https://www.cdc.gov/lice/hcp/clinical-care/index.html

  Both over-the-counter and prescription medications are available to effectively treat head lice. […] If the medication you use does not kill nits (lice eggs), then retreatment is recommended. […] Pyrethrins can only kill live lice, not unhatched eggs (nits). Treat a second time 9-10 days after the first treatment to kill any newly hatched lice before they can produce new eggs. […] Permethrin kills live lice but not unhatched eggs. Permethrin can kill newly hatched lice for several days after treatment. You may need to treat again on day nine to kill any newly hatched lice before they can produce new eggs. […] Benzyl alcohol kills lice but does not kill eggs. Treat again after 7 days to kill any newly hatched lice before they can produce new eggs. […] Ivermectin lotion, 0.5% kills lice and, although it does not kill eggs, appears to prevent nymphs (newly hatched lice) from surviving.

• #8 Clinical Care of Head Lice | Lice | CDC

  https://www.cdc.gov/lice/hcp/clinical-care/index.html

  Malathion is pediculicidal (kills live lice) and partially ovicidal (kills some lice eggs). A second treatment is recommended if live lice still are present 7-9 days after treatment. […] Spinosad is derived from soil bacteria. Since it kills live lice as well as unhatched eggs, retreatment is usually not needed. […] Lindane is effective at treating lice but is no longer available in the United States or Canada due to its risk for severe side effects. […] Do not use extra amounts of any lice medication unless instructed to do so by your physician and pharmacist. […] Do not treat a person infested with lice more than 2-3 times with the same medication if it isn’t successful. […] The AAP recommends rinsing all topical pediculicides from the hair over a sink, rather than in the shower or bath to limit skin exposure.

  https://caringforkids.cps.ca/handouts/health-conditions-and-treatments/head_lice

  Head lice can be treated in a variety of ways: […] Insecticides are chemicals that kill insects. In Canada, 2 insecticides are approved to treat head lice: pyrethrin (found in RC shampoo + conditioner) and permethrin (Nix creme rinse or Kwellada-P creme rinse). […] Pyrethrin and permethrin are safe when used on humans over 2 months old. You do not need a prescription. Over time, head lice have become resistant to some of the chemicals used to kill them, so some products may be less effective than they used to be. But they are still worth trying. […] How to apply insecticides: Follow package directions carefully. Don’t leave the shampoo or rinse in the hair longer than directed. Rinse hair with cool water after the treatment. It’s best to rinse over a sink, not in the bath or shower, so that other body parts don’t come in contact with the product. Repeat the treatment after 7 to 10 days, in case new lice hatched from the nits.

  Non-insecticides: Isopropyl myristate/cyclomethicone (Resultz) is approved for use in Canada, but it should only be used in children 4 years of age and older. It dehydrates the lice and they die. Apply to a dry scalp and rinse with warm water after 10 minutes. Repeat after 1 week. […] Silicone oil dimeticone (NYDA) is effective against live lice, nymphs and nits. It is not recommended for children under 2 years old. A second treatment is recommended after 8 to 10 days. […] Benzyl alcohol lotion 5% (Ulesfia) is effective against live lice, but a second treatment is recommended after 9 days. […] These products are usually more expensive than insecticides. It is not known for sure whether they work better. […] Some people suggest home remedies such as mayonnaise, petroleum jelly, olive oil, vinegar or margarine. Although these products may make it hard for lice to breathe, they probably won’t kill them.

  There is little evidence that wet combing (removing lice by combing wet hair with a fine-tooth comb) works all on its own. […] There is no evidence that products such as tea tree oil or aromatherapy work to treat head lice. […] Ivermectin is a drug that can be taken by mouth or used as a cream, but it is not approved for use in Canada. […] Never use gasoline or kerosene. These products can be extremely dangerous.

  In some regions, lice have developed resistance to nonprescription medications. Nonprescription treatment also may fail because of incorrect use, such as not repeating the treatment at an appropriate time. […] If the correct use of a nonprescription treatment has failed, your health care provider may recommend a prescription treatment. […] If you prefer not to use a medication for treating head lice, you may consider a home treatment. However, there’s little to no clinical evidence that home treatments are effective. […] Combing wet hair with a fine-toothed nit comb may remove lice and some nits. Studies show that wet-combing results vary. […] A number of household products are used to treat head lice. These products are thought to deprive the lice of air when generous amounts are applied to the hair, covered with a shower cap and left on overnight.

  According to the American Academy of Pediatrics guidelines, the gold standard for diagnosing head lice is to identify a live nymph or adult louse. […] Your health care provider will likely recommend a medication available without a prescription that kills lice and some of the nits. These medications may not kill recently laid eggs. Therefore, an appropriately timed second treatment is usually necessary to kill nymphs after they hatch but before they become adult lice. […] Some studies suggest that re-treating 7 to 9 days after the first treatment is the ideal time for a second treatment, but other re-treatment schedules exist. Ask your health care provider for written instructions for a recommended treatment schedule. […] Permethrin doesn’t kill nits, and treatment needs to be repeated 9 to 10 days after first application.

  Dimethicone is effective, safe, and affordable and can also be used in all age groups. […] Treatment with pesticides can be harmful to human health and the environment and is often not the most effective solution for head lice. […] Select insecticidal shampoo products carefully. Always read the label carefully and follow the directions. […] If live lice are found a day after treatment, suspect that resistance is occurring and discontinue use of that product. […] An effective treatment protocol for treating heads of hair that cannot be combed include using a dimethicone-based product. A series of 3 dimethicone treatments made 5 to 6 days apart can reliably eliminate lice without the need to comb nits out.
