About This Condition
Head lice (Pediculosis capitis) is an infestation of the hair and scalp by a mite called Pediculus capitis. Head lice affects mainly children and the mite can either be passed directly by person to person contact, or indirectly when the organism is deposited on shared articles such as clothing, furniture, bed linens, or hairbrushes.1
Itching of the scalp, which can be very intense, is the most common symptom of head lice. There may be small crusts of dried blood around sites where bites have occurred, and combing with a fine-tooth comb may pick up eggs (nits) that have been attached to the hair shaft.2 , 3
Healthy Lifestyle Tips
Maintaining a clean personal environment is essential for the prevention and control of head lice. This means that clothing, bedding, and personal hair care items such as brushes and combs should be washed regularly. Regular vacuuming of floors, furniture, and play areas will remove hairs that might harbor nits.4
Head lice and their eggs may be removed by using hair conditioner, followed by combing through the wet hair with a fine-tooth comb.5
Several home remedies have been popularized for treating head lice, including topical application of isopropyl alcohol, olive oil, mayonnaise, melted butter, and petroleum jelly. Test tube studies of these remedies found that only petroleum jelly was effective for killing lice and their eggs,6 but no human studies have investigated whether any home remedy is an effective treatment for an existing infestation.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Spray a 3.7% lotion in a slow-release formula every morning six days per week
Citronella is a volatile oil that has been shown to help eliminate head lice.
Citronella is the volatile oil extracted from Cymbopogon nardus or Cymbopogon winterianus. In a double-blind trial, children with head lice were treated either with a placebo lotion or a lotion containing 3.7% citronella in a slow-release formula.7 The lotions were sprayed on the hair every morning for six days each week. Reexamination after two and after four months showed that significantly fewer children using citronella lotion were still infested.
Apply an alcohol extract to the scalp two times, one week apart
Quassia is a tree native to the Amazon rainforest that has constituents with activity against several types of microbes and insects.
Quassia (Quassia amara) is a tree native to the Amazon rainforest that has constituents with activity against several types of microbes and insects.8 , 9 , 10 An uncontrolled study reported that all but three out of 454 cases of head lice were successfully treated with a topical tincture of quassia bark applied to the scalp once, and again one week later.11 A double-blind trial found that using a similar quassia extract helped prevent new cases of head lice.12
Apply a cream containing 20% seed oil to hair and wash out three hours later
In one trial, a cream containing 20% oil of sugar apple seed killed 95% of head lice when applied once to the hair of infested schoolgirls for three hours, and then washed out.
Sugar apple (Annona squamosa) is a tree native to Latin America, the Caribbean, and Southeast Asia. In a controlled trial, a cream containing 20% oil of sugar apple seed killed 95% of head lice when applied once to the hair of infested schoolgirls for three hours, and then washed out.13
Anise, Ylang Ylang, and Coconut Oils
Refer to label instructions
A combination of anise, ylang ylang, and coconut oils has been shown to be effective against head lice.
A commercial product (HairClean 1-2-3) containing oils of anise, ylang ylang (Cananga odorata), and coconut, plus isopropyl alcohol, applied once per week for 15 minutes followed by rinsing, shampooing, and combing, was 98% effective, according to a preliminary report of a controlled study.14
Paw Paw, Thyme Oil, and Tea Tree Oil Shampoo
Apply shampoo to hair and leave on for one hour before washing out
An herbal shampoo containing a standardized extract of paw paw, thyme oil, and tea tree oil has been found to be effective in treating head lice.
An herbal shampoo (Paw Paw Lice Remover Shampoo) containing a standardized extract of paw paw (Asimina triloba), thyme oil, and tee tree oil was found to be toxic to head lice in test tube studies, after which uncontrolled trials were carried out in 13 families.15 The shampoo was applied to the dry hair and left on for one hour before washing out and combing with a fine-toothed comb; this was repeated eight and sixteen days later, after which 100% of the 37 participants were free of lice.
Apply a cream containing 20% seed oil to the hair and wash out three hours later
Traditional herbalists recommend applying oil of sassafras to treat head lice.
Traditional herbalists recommend applying oil of sassafras topically three times per day for lice, but this has never been tested in a clinical study.16
