What repels head lice? Coconut, tea tree oil, lavender, eucalyptus, rosemary, lemon grass, and peppermint are scents popularly believed to repel lice. Using any coconut scented shampoo and conditioner is an easy way to increase your defense. At 1% concentration, tea tree oil killed 100% of head lice after 30 minutes.
Lice 'scaring' shampoos and sprays do not get rid of existing lice but are designed to prevent lice, using natural lice repellents such as peppermint and tea tree oil. Most of these products are non-toxic, and can be purchased anywhere.
Lavender Oil Shampoo
Lice can be prevented due to the same antiseptic properties through the use of lavender shampoo or by adding lavender oil to other shampoo. Because of the lower concentration of terpenoids, lavender oil shampoos are much safer to use than tea tree oils and provokes very few skin irritations.
Dawn dish soap has quite a long list of ingredients; however, none of them are proven to harm or kill lice or nits.
Dandruff shampoos like Head & Shoulders work by using the active ingredient, zinc pyrithione. It helps protect your scalp from dandruff-causing oleic acid. It's been proven on dandruff, but does nothing to inhibit lice.
Adults are not immune to head lice. In fact, if you have any close contact with children or even parents of children you can be at risk of catching them if they have them. Lice transfer primarily through head to head contact, so you would have to get close to the other person.
Lice are attracted to the blood they get through your scalp – short, long, clean or dirty.
Heat Method:
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.
Lice and nits can't survive the high heat. It's true that lice and nits can't survive temperatures above 113°F (45°C). This makes them susceptible to any heat source, such as a hairdryer or the plates of a hair straightener.
Either washing done with a water temperature of at least 50 degrees C or drying is necessary to kill head lice and nits.
Tea tree oil appears to be able to kill some live lice (at least when used in conjunction with lavender oil), however we know that over-the-counter lice treatments are far more effective at killing live lice and getting rid of the eggs once an infestation has occurred.
As far as we know, there have not been any clinical studies proving any human population to be immune to head lice. However, head lice can have difficultly attaching their eggs to hair that is thick or coarse; therefore, those individuals may be less likely to experience head lice infestation.
Head lice most often affect children. The insects usually spread through direct transfer from the hair of one person to the hair of another. Having head lice isn't a sign of poor personal hygiene or an unclean living environment. Head lice don't carry bacterial or viral diseases.
They need human blood to live. Head lice usually stay close to the scalp and behind the ears. You might also spot them on the eyebrows and eyelashes.
Infestation timeline
So if you look on the scalp and see no visible adult lice and several small nits, it's likely that you've caught lice in the earlier stages and had them for less than 2 weeks. Nits and nymphs: 1.5 to 2 weeks. If you see nits and small, moving lice, you've likely had lice for 1.5 to 2 weeks.
No one is immune, but frequent head checks help
Anyone can get lice, and personal hygiene has nothing to do with the likelihood of being infested, Rukke said.
Indications of head lice infestation include: the tickling feeling of something moving in the hair, itching, feeling irritable or having difficulty sleeping, and having sores on the head caused by scratching. How soon after exposure do symptoms appear? Itching might begin a few days to several weeks after infestation.
Lice Hate Coconut!
Swap out your hair care products for some that are coconut scented or are made with natural coconut oils. Some studies have shown lice are repelled by the smell of coconut. If you're attached to your shampoo brand, you can simply add a few drops of coconut oil to it for a similar effect.
Getting rid of head lice
Unfortunately, even a shampoo as effective as Head & Shoulders won't help when it comes to head lice.
Vinegar contains properties that kill and get rid of nits and lice. This mixture should be applied directly to the whole scalp. Mix 1 cup of vinegar with 1 cup of warm water. Next, distribute this mixture onto the scalp and cover your hair with a hair cap.
Can adults get head lice? Adults can get head lice, but they're most common in children aged between four and 11. If you have head lice, you'll usually have up to around 30 lice living on your scalp. But, there could be up to 1,000 lice if you have a very bad case of lice.
Head-to-head contact with an already infested person is the most common way to get head lice. Head-to-head contact is common during play at school, at home, and elsewhere (sports activities, playground, slumber parties, camp). Although uncommon, head lice can be spread by sharing clothing or belongings.
Some studies suggest that girls get head lice more often than boys, probably due to more frequent head-to-head contact. In the United States, infestation with head lice is much less common among African-Americans than among persons of other races.
They found vinegar was actually the least effective treatment method for getting rid of lice or suppressing the hatching of nits. Vinegar wasn't the only home remedy that didn't do well. No home treatment prevented lice from laying eggs. Even with prolonged exposure, most home remedies were unable to kill nits.
