There are so many urban legends and myths concerning the best home remedy for head lice, including suffocating them with mayonnaise, olive oil, motor oil, shaving all your body hair, and others.
Few have merit apart from a few essential oils, a few dust compounds containing diatomaceous earth, and of course some of the over the counter remedies.
As for a home remedy for head lice, some over the counter remedies and prescriptions contain dangerous chemicals like pyrethrins, pyrethrins, malathion and lindane. Source
Links between pyrethroids and childhood brain cancers
Perhaps one reason people search out a home remedy for head lice is,a study of pesticides and childhood brain cancers has revealed a strong relationship between brain cancers and compounds used to kill fleas and ticks, according to a report published in Environmental Health Perspectives. The study concludes "The specific chemicals associated with children's brain cancers were pyrethrins and pyrethroids (which are synthetic pyrethrins, such as permethrin, tetramethrin, allethrin, resmethrin and fenvalerate) and chlorpyrifos (trade name: Dursban)." [Janice M. Pogoda and Susan Preston-Martin, "Household Pesticides and Risk of Pediatric Brain Tumors," Environmental Health Perspectives, vol. 105, no. 11 (November 1997), pages 1214-1220.] The EPA, in June 2000, halted sales of Dursban.Source
the best home remedy for head lice?
In my opinion, the best of all home remedies for head lice is tea tree oil. Tea tree oil is well suited as a home remedy for head lice,because it contains several components that have proven themselves in studies to kill lice. In a study published by Scandinavian University Press, in 1999 in Acta Derm Vernereol 1999; 79: 1-2., several of the chemical compounds in tea tree oil, and tea tree oil itself, was tested in a 10% solution.
In several of the compounds, they worked to kill 50-100% of the head lice. Tea tree oil, in a 10% solution, killed 85% of the headlice. If you were to apply the tea tree oil in a slightly stronger solution, it should work much more effectively, and a shampoo or conditioner with a 3% or better solution should help with head lice prevention.
So, how do you go about treating head lice with tea tree oil as a home remedy for head lice,? In the past I devoted an entire newsletter to the problem of treating lice infection with tea tree, and it covered it in detail.
Since then, after researching more, and in finding results like the study above, by far one of the simplest of lice home remedies is to mix a solution of tea tree oil and a carrier oil like olive, grapeseed, or almond oiland then shampoo it out, or use both methods combined.
The recipe is simple. Here’s what you will need.
At least 1 ounce of 100% pure Australian tea tree oil (30ml) dark glass bottle only!Carrier oil ( almond, olive or grapeseed)A shower capTea Tree Oil shampoo (if you don’t have this, add 5 or ten drops of tea tree oil to a good quality shampoo.)
We also recommend a high quality body wash for your bath or shower, and if this whole episode has put you under added stress, it's wise to supplement your body nutritionally to help it handle the added strain on your system.
Mix 1 teaspoon (5ml) or (60 drops) of tea tree oil to 4 tablespoons (60ml) of carrier oil. Thoroughly rub this mix into the hair and scalp and let it work on killing lice for 10-15 minutes. This is a 10% solution of tea tree oil, and it has been proven in the study listed above to kill the lice.
Tea tree oil has a cooling effect, and so you may experience a little tingling sensation, similar to menthol, but not nearly so intense. This is normal, but in a mild solution such as this, you may not feel any cooling sensation at all, unless you are treating a particularly sensitive skin area.
After two hours, all of the lice should be dead. Remember to put on clean, preferably freshly laundered clothes, as lice can survive for two days off of your body.
Examine the treated areas for any live lice, and use the tea tree oil shampoo daily. In some research, tea tree oil was found more effective than the insect repellent DEET in repelling lice. Tea tree oil shampoo has been used by many families to help prevent re-infestation of lice.
Lice lay eggs called nits, and the nits hatch in 7 to 11 days, so it is recommended to repeat the tea tree oil/ olive oil treatment a second time about one week later. The tea tree oil will most likely have killed all of the nits, but if any items of clothing, bedding, carpeting, or furniture were missed in the vacuuming, washing, and general cleanup, or if any nits survived, you will want to kill them off.
If the oil treatment seems a little severe, or you can’t stand the idea of putting oil in your hair that may be difficult to remove, consider the following treatments.
Three Levels of Treatment
There are basically three levels of treatment, and just how bad an infection you have, or how aggressive you want or need to be in your treatments will most likely decide which one would work best for you.
All of these levels of treatment assume that you are vacuuming all carpets and cloth upholstery every day, and putting on freshly laundered clothes after treatment, along with laundering all bedding.
Level 1 home remedy for head lice,
This is the least bother, works for some folks, and is fairly simple. Just get a great tea tree oil shampoo, add ten drops of tea tree oil to the normal amount of shampoo you regularly use, and shampoo your hair. Allow it to remain in your hair for about ten minutes, and then rinse and follow your normal routine.
Doing this twice a week for several weeks has helped lots of folks get rid of lice. As a preventative and maintenance program, shampoo with tea tree oil shampoo, and perhaps tea tree oil conditioner. With the tea tree oil shampoo we use, no extra conditioner is needed, the botanicals in the shampoo condition hair naturally.
Level 2 home remedy for head lice,
A little more work, and most of the time necessary. With this home remedy for head lice, you’ll need a nit comb. This fine toothed comb is run through every single strand of hair after coating the hair with tea tree oil shampoo or conditioner, or with the oil mix listed above. Wet the hair, apply a generous amount of conditioner, and with a towel handy to wipe the nit comb off whenever nits or lice are combed out, thoroughly comb the entire scalp, nape of the neck, and all of the hair. You’ll need to use the nit comb every day for about two and a half weeks, or until no nits or lice are found.
After the conditioner and combing, follow the instructions in level 1 treatment above
