  The head louse, Pediculus humanus capitis, can infest people of all ages, but most commonly affects children 4 to 12 years of age since they often play in close contact with one another. […] While head lice infestation causes limited health impacts for most people, it can cause a great deal of anxiety and embarrassment. Head lice are not a health hazard and do not transmit disease-causing pathogens, nor do they indicate poor hygiene. […] Diagnosis of a head lice infestation requires the detection of a living louse crawling on the scalp. The presence of nits is not a reliable indication of an active infestation that needs to be treated. […] There are seven critical steps to controlling an infestation of head lice: […] Using an effective head louse treatment, with all infested individuals treated at the same time, to prevent re-infestation from others. In most cases, nits will require re-treatment in 7 to 10 days. No treatment is 100% effective at killing the nits.

  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. […] 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.

  Combing can be undertaken every 1-3 days. This method not only is for treatment but can be for prevention, to remove mature lice which might otherwise lay eggs and perpetuate the life cycle. […] However, it was also demonstrated that the diagnosis of louse infestation using a louse comb is four times more effective (25% versus 6%) than direct visual examination and twice (57 seconds versus 116 seconds) as fast. […] The fight against pediculosis is certainly a very ancient concern and various methods have been used to get rid of it. […] The posttreatment reemergence of lice is common and still remains a real challenge. Treatment success depends on improving our knowledge of the fundamental biology and physiology of the louse. […] It is important to notice that per os treatment may have more secondary effects as all other oral medicines than external products. […] The effectiveness of this combination has also been confirmed in naturally infected dogs with Dirofilaria immitis. […] Thus, we conclude that the synergistic effect is one of the most effective means of lice treatment and also prevents reemergence and resistance.

  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. […] A health care provider may diagnose body lice if they find eggs or crawling lice in clothing seams or on bedding. […] A health care provider may diagnose pubic lice when they see moving lice or nits on hair in the pubic area or on other areas of coarse hair, such as chest hair, eyebrows or eyelashes. […] Use drugs that treat lice only as directed. Applying too much can cause red, irritated skin. […] Head lice treatment may involve: Nonprescription products. Shampoos containing permethrin (Nix) are usually the first option used to combat lice. […] A lotion containing ivermectin (Sklice) also is available without a prescription.

  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. […] Many head lice medications are available over-the-counter. […] 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. […] The following prescription medications, in alphabetical order, are approved by the FDA for head lice treatment. […] Benzyl alcohol is an aromatic alcohol. It kills lice but does not kill eggs. Treat again after 7 days to kill any newly hatched lice before they can produce new eggs.

  Rid is a shampoo made from chrysanthemum extract that is toxic to lice but only has a low toxicity in humans and other mammals. […] LiceMD Pesticide Free is another type of OTC anti-lice shampoo. Known as an occlusive agent, it uses dimethicone. This is a non-toxic form of synthetic silicone oil. It works by closing off the lice’s breathing spiracles and smothering them. […] While combing is a recommended part of an anti-lice shampoo treatment, it’s also a useful home remedy in and of itself. […] You may remove the nits and live lice with a lice comb and tweezers. This is a recommended part of an OTC treatment course but is also useful as an alternative for those interested in a natural approach. […] If you are having trouble getting rid of lice, your healthcare provider may suggest a prescription-strength medication.

  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. […] However, it’s unclear if these treatments are effective. […] Another option is a machine that uses one application of hot air to kill head lice and their eggs through dehydration.

  Ivermectin lotion, 0.5% is approved for people six months of age and older. It kills lice and, although it does not kill eggs, appears to prevent nymphs (newly hatched lice) from surviving. […] 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. […] The AAP recommends rinsing all topical pediculicides from the hair over a sink, rather than in the shower or bath to limit skin exposure.

  Use of a nit comb to remove lice and nits after treatment may help to decrease risk for reinfestation. Nit combing can be performed every two to three days for two to three weeks. […] 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. […] Because there is no evidence that these treatments are predictably effective, we do not recommend any of these treatments.

  To guide staff with the assessment and management of head lice. […] Failure to follow this guideline may result in inadequate treatment of head lice. […] There are two main management options: Insecticide, Mechanical removal (10 day conditioner method). […] An important part of insecticide management involves manual removal of eggs with a nit comb after treatment with an insecticide. […] Resistance to pyrethrins has been reported internationally, therefore it is appropriate to use a different type of insecticide if the infestation is not adequately treated or recurs. […] Insecticides: Advised to use in conjunction with conditioner treatment. […] The saturation of dry hair with hair conditioner (any type) will immobilise fast moving lice, allowing manual removal with a nit comb. […] The procedure must be repeated daily for 10 days to ensure removal of new lice as they hatch. […] There is no evidence that other products are effective. E.g. tea tree oil, sassafras oil.
