Will Apple Cider Vinegar Kill Lice Eggs?

Apple cider vinegar is reportedly useful for treating and preventing head lice, according to anecdotal evidence.

In actuality, a 2004 study refutes the effectiveness of vinegar consumption. Researchers investigated six prominent alternative therapies for treating head lice infestations, including:

  • vinegar
  • alcohol isopropyl
  • olive juice
  • mayonnaise
  • melting butter
  • petroleum glycerine

They discovered that vinegar was actually the least effective technique for treating lice or preventing the development of nits.

The failure of other natural remedies wasn’t limited to vinegar. No over-the-counter medication stopped lice from reproducing. Most household therapies failed to eliminate nits, even after extended exposure. But killing a sizable number of lice required merely the application of petroleum jelly.

The Penn State Department of Entomology claims that vinegar is ineffective at removing nits from the hair shaft.

How does apple cider vinegar work to get rid of lice eggs?

Apple cider vinegar is ineffective for treating lice, as we’ve already said. Other efficient methods to get rid of lice are listed below:

  • One of the greatest techniques to get rid of head lice is to wet comb your hair. Wet combing is the simplest method for getting rid of lice, according to a study done in Belgium (2). Spray the resulting mixture throughout your hair after combining some conditioner and water in a spray bottle. After that, use a nit comb to get rid of the eggs and lice.
  • Applying coconut, olive, or almond oil will also suffocate lice. Smothering merely serves to slow down the lice, making it simple to remove them with a nit comb.
  • Using essential oils such as tea tree oil, lavender oil, eucalyptus oil, peppermint oil, or clove oil may also be an option. Using a cotton ball and this method, you would combine 2 ounces of olive oil with 15 to 20 drops of the essential oil. Give the oil 12 hours to absorb into your hair. Before you wash off the oil, remove the lice and nits using a comb. Follow this procedure daily until you are certain that your hair is free of any live lice or nits.
  • To stop the lice from spreading, thoroughly clean and sanitise all of your combs and other hair accessories, including hair clips, hats, and scarves.

Clinical evidence does not support the use of apple cider vinegar to treat lice infestations. Although it has not been proven to be a successful treatment for lice, people have been using it for that purpose. You can use it if you wish to try it out by using the procedure described in this page. You can also give alternative solutions to your lice infestation a try. You can avoid it by adhering to those and maintaining an appropriate hair care routine. However, seek medical attention right away if home cures do not work.

How can lice eggs be quickly eliminated?

You might be tempted to conduct a frantic cleaning campaign around the house if you or your child has lice, but you can rest confident that this isn’t always necessary.

Since nits often don’t hatch at room temperature, lice won’t live very far from the scalp. So put off doing a thorough cleaning of the house till later.

However, items like caps, pillowcases, brushes, or combs that have come into touch with the individual who has lice should be cleaned or washed. Fill a plastic bag with sentimental stuffed animals and other non-washable objects.

Any object with lice should be washed in hot water that is at least 130°F (54°C), dried in a hot environment for at least 15 minutes, or placed in an airtight plastic bag and left for two weeks to eliminate the lice and any nits.

Mix Apple Cider Vinegar and Mineral Oil

Mineral oil and unfiltered apple cider vinegar should be combined in an equal ratio in a bowl. Then, before going to bed, apply the mixture to your hair and scalp. Put on a shower cap after applying the mixture, and let it sit overnight. Wash and thoroughly rinse your hair with ordinary shampoo in the morning. After that, use a nit comb to comb the lice out of your moist hair. Once every week, you can carry out this procedure again until the lice are entirely gone.

Another method of using apple cider vinegar to get rid of lice is to combine it with salt and a little oil. You only need to reheat 1/4 cup of apple cider vinegar and 1/4 cup of salt to do this treatment. Be sure to stir it thoroughly so that the salt is completely dissolved. Then, for simpler administration, pour the liquid into a spray bottle.

Spray the prepared mixture all over your hair and scalp. Allow the liquid to permeate the hair follicles. Apply warm olive or coconut oil to your hair and scalp once it has completely dried. To suffocate the lice, leave it on for at least two hours or overnight if you can. Use a nit comb to remove the lice after a few hours or in the morning (if you decide to keep it on overnight). Finally, thoroughly rinse your hair after using a lice shampoo.
