Of the tested remedies, the team found that pure coconut oil was the only effective treatment. Within 4 hours of applying the oil, an average of 80% of the head lice were dead. The two most effective medicated shampoos killed 97.9% and 90.2% of lice in the same period.
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.
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.
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.
The thick consistency of coconut oil suffocates head lice and their eggs. It also prevents lice from transferring onto your clothes. Coconut oil contains fatty acids that make it difficult for the lice to hang on your hair strands.
Permethrin lotion 1% is approved by the FDA for the treatment of head lice. Permethrin is safe and effective when used as directed. Permethrin kills live lice but not unhatched eggs.
Olive Oil smothers and kills active head lice, making nit removal easier and moisturizing the hair and scalp.
The researchers found that tea tree and peppermint oil repelled lice the most, and a tea tree and lavender combination kept some lice from biting people with treated skin. Overall, tea tree oil was the most effective, followed by DEET, coconut, and a botanical mixture.
Pile hair on head, if needed, and cover with a close-fitting shower cap OR cut plastic bag and wrap around head. Use scotch tape or hair clips to keep on the head. Leave cap or bag on for as long as possible (at least 4 hours BUT works best for 8+hours). Remove all nits as discussed under the Nit Removal Section below.
Cover all of the hair with conditioner, detangle hair with normal comb and separate into sections. Then, using a fine long toothed metal lice comb, comb through the hair in sections. The conditioner does not kill lice but stuns them for about 20 minutes enabling easier removal.
Rosemary Repel is the top choice for being a lice shampoo but it is also gentle enough in being a everyday kids shampoo or as a everyday shampoo for adults. Harnessing the power of natural ingredients, Rosemary Repel is clinically proven effective to help prevent head lice without the use of harmful ingredients.
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.
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.
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.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.
The only way to prevent them from hatching would be to remove them with a good metal nit comb, or your fingernails. Nits are laid by the mother and attached with a glue she formulates, to sit on the hair shaft in the perfect spot to incubate and hatch.
Lice and nits can live on pillows and sheets. Lice glue their eggs to the hair strands of their host. However, if a piece of hair with an egg falls out while the lice host is sleeping, an egg could end up on pillows or sheets.
Generally, if no live crawling insects are seen three weeks after the treatment, it's safe to assume that they are gone. Nits would have hatched by that time if they were alive. Nits and their shells may remain in the hair for some time but won't be viable.
Head lice cannot live for long on pillows or sheets. It is possible for a live louse that has come off a person's head to crawl onto another human host who also puts their head on the same pillows or sheets.
Petroleum jelly (Vaseline).
Like olive oil, many moms swear by this (other options: styling gel or mayonnaise). The thick jelly supposedly suffocates lice by clogging their breathing holes. For best results, coat the hair and scalp, cover it overnight with a shower cap, and wash out the next morning. Comb for nits.
Use heat. Wash any items used or worn by the person in hot water, and dry them on high heat. Lice and nits die when exposed to temperatures higher than 130 F for more than 5 minutes. Wash anything that touched the person's skin or scalp, including jackets, hats, scarves, pillowcases, sheets, and headbands.
If a head lice treatment that you can buy without a prescription fails to work, the CDC recommends that you see a health care provider. Highly effective prescription treatments that you apply to the scalp are available.
