Olive Oil smothers and kills active head lice, making nit removal easier and moisturizing the hair and scalp.
The oil must remain on the head for at least 8 hours to be effective. Even though it is very likely that a single application of the oil will kill all stages (eggs, nymphs and adults) of the lice, I recommend retreatment about 7 days after the initial treatment.
Suffocate the Lice
Soak your child's head in olive oil or coconut oil. Cover with a shower cap for at least 2 hours (or preferably overnight). When ready, remove the shower cap, and separate the hair into small sections, then use a metal nit comb to carefully remove the lice and eggs.
Smothering agents.
Some people try to suffocate and kill lice by putting large amounts of a greasy substance on your scalp, covering with a shower cap, and leaving it on while you sleep. You can try petroleum jelly, mayonnaise, or olive oil.
Using Olive Oil On Your Hair
Basically, you apply the olive oil to your hair, and leave it on for 6 to 8 hours. This is supposed to suffocate the lice. You then use a lice comb to physically remove them from your hair. You repeat this process until no more lice shows up in the lice comb.
The researchers compared tea tree oil, lavender oil, peppermint, and DEET. On its own, tea tree oil was the most effective treatment tested. Tea tree oil and peppermint appeared to be most useful for repelling lice. Tea tree oil and lavender were also found to prevent some feeding by lice on treated skin.
No. The two treatments 9 days apart are designed to eliminate all live lice, and any lice that may hatch from eggs that were laid after the first treatment. Many nits are more than ¼ inch from the scalp.
The coconut oil should be at or slightly above room temperature so that it's in a liquid form and easy to spread throughout your hair. Massage the coconut oil generously throughout your hair, and apply the plastic shower cap right away. Leave the cap on for eight hours (or more) to suffocate the lice.
The conditioner does not kill lice but stuns them for about 20 minutes enabling easier removal. The long toothed metal comb will remove nits and the stunned head lice. Wipe the comb on a white tissue and check for any lice or nits. Keep combing until no more appear on the tissue.
Spinosad (Natroba).
Spinosad is approved for adults and children age 6 months and older. It can be applied to dry hair and rinsed with warm water after 10 minutes. It kills lice and nits and usually doesn't need repeated treatment.
While thick consistencies such as mayo, coconut oil and Vaseline can sometimes be effective in killing the adult bugs, they have little to no effect in killing a nit or baby louse. Nits MUST be manually removed from the hair strand to kill it. Myth #4: Over the counter head lice treatments are safe and effective.
In addition to removing the live bugs from the hair with the comb, you can use olive oil to kill lice by saturating the hair in it and leaving it on for 8 hours (lice can hold their breath for that long) so that the oil will suffocate the bugs.
Coconut oil relies on its viscosity (attributed to its fatty content) to suffocate head lice by choking their breathing systems, and in the process killing them. There is a documented proof of it. That being said, when you talk about nits (lice eggs), they are immune to the action of a suffocating agent.
After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2–3 days may decrease the chance of self–reinfestation. Continue to check for 2–3 weeks to be sure all lice and nits are gone.
Blow dry their hair completely. This will take a long time but it helps “seal in” and suffocate the live lice. Put a shower cap, head wrap or skull cap on and leave the dried lotion on for at least 8 hours. It's easiest to do this overnight.
Nits are often confused with other things found in the hair such as dandruff, hair spray droplets, and dirt particles. If no live nymphs or adult lice are seen, and the only nits found are more than ¼-inch from the scalp, the infestation is probably old and no longer active and does not need to be treated.
There are recent studies that show that treatment of lice with heat can be quite effective in killing head lice. Products such as Lousebuster are very effective but even a home hairdryer can successfully treat lice.
Sometimes it will be easier to remove the nits if you wet the hair with white vinegar while you are combing the nits out. Vinegar helps loosen the "glue" that holds the nits to the hair. Separate and comb small sections of hair at a time.
Typically, 10–15 head lice are found. The number of lice often depends on personal hygiene, for example, how often the person bathes, shampoos, or changes and washes his/her clothing.
Adult lice can't live longer than 24 hours or so on nonhuman surfaces like carpets, hardwood floors, clothing, furniture, sports helmets, headphones, or hair accessories. However, if you have identified lice in your home, isolate and wash those items and areas within at least 72 hours.
You can find head lice on the scalp, neck, and ears.
Lice can be tricky to get rid of because nits can remain unhatched on your head or you might pick up lice that are still on bedding or other items. Here's what to do if you've had lice — or someone in your family has: Wash bed linens and clothing that anyone with lice has used recently.
If you're infested with body lice for a long time, you may experience skin changes such as thickening and discoloration — particularly around your waist, groin or upper thighs. Spread of disease. Body lice can carry and spread some bacterial diseases, such as typhus, relapsing fever or trench fever.
The olive oil will suffocate the lice, but not the eggs and you will need to repeat the treatment several days later until all of nits are removed. Other types of suffocating agents have been suggested, but olive oil appears to be the most effective.
Wash any lice-infested item in hot water that is at least 130°F (54°C), put it in a hot dryer for 15 minutes or more, or placing the item in an air-tight plastic bag and leaving it for two weeks to kill the lice and any nits. You can also vacuum floors and furniture where lice may have fallen.
