How Lavender Oil Can Help You Treat And Repel Head Lice

Lavender essential oil

If you are looking for safe and natural ways to treat head lice, you should consider using lavender oil.

This treatment does not contain any pesticides and can be used as a home pediculicide in case you are not allergic to lavender and lavender essential oil.

Let’s take a look at how lavender oil works and if it can kill or repel head lice.

Lavender oil is considered to be a natural insect repellent. It affects insects with its smell.

Of course, no matter how much lavender or any other essential oil you use, such as tea tree oil, it cannot guarantee you that you will not get lice and nits.

You still get chances of getting infested with head lice, but what happens is that you reduce your risks of getting infested when using lavender oil or lavender shampoo.

According to research, over 90 percent of people who used lavender or tea tree essential oils on their hair did not get infested with head lice or got rid of the ones they already had.

Does lavender repel head lice? Yes, this home remedy does work for repelling lice.

Now, let’s see how you can use lavender oil to help get rid of adult lice. The best way to use it is in combination with some carrier oil . This treatment method is called a physical pesticide.

Here is what you can do. You take a sufficient quantity of the carrier oil; you can use coconut oil, corn oil, olive oil, sunflower oil or any other kind of natural plant oil as your carrier oil.

Then, you add a teaspoon or just a few drops of lavender oil to the carrier oil. Now you are ready to apply it to your hair. Apply the mixture to dry and clean hair, and cover the head with a shower cap.

Leave the oils on your hair and scalp for several hours.

Does lavender deter head lice? Yes, lavender oil can help to suffocate and repel these parasites (but not their eggs).

The mixture of oils gets stuffed into the adult lice breathing tubes, preventing them from breathing, and they die.

Keep in mind that this is not 100% effective, of course, just like many other treatments and remedies.

One of your best bets is to use a proven, safe shampoo like this one:

You should also keep in mind that lavender oil does not kill nits. This is why a repeated treatment is needed 7 to 10 days later.

You can also use lavender oil for combing out lice. You put it on a special lice comb and comb out your hair lock by lock.

Lavender oil remains on the hair and repels head lice. They find it hard to return to the combed and clean locks.

You can also use lavender shampoo. You can make it yourself by adding a few drops of the essential oil to the shampoo.

Using such shampoo can help you to repel head lice and keep them away once you have gotten rid of them. However, it may not provide a real treatment on its own.

As you can see, lavender oil can offer you safe solutions for treating lice at home. Make sure you are not allergic to this essential oil before applying it.


I have had lice multiple times more as a child, and I had used those harsh chemicals to get rid of them too. When I was little some of that product has slipped into my left eye, and I have had damaged sight ever since! I have not tryed this yet but am sure to after I start with tea tree oil. I will combine them and get back to you on how well it works! My friend uses it for her kids and she hasn’t had a problem since!

Thanks for the article! I read a number of research studies on essential oils for getting rid of head lice and found your site.

The best way to repel head lice is to mix lavender oil, tea tree oil, and carrier oil (my favorite is olive oil for deep nourishment) with 3%

5% ratio. Also, do not use essential oil alone (always mix with carrier oil), it can increase the sensitivity of your skin.

I didn’t know my son had headlice, I had given him a head scalp massage with olive oil and lavender oil 2 nights before, he told me he had an itchy head and i looked and he had lice but they were dead!!
Must have been the lavender oil so I googled and found this! I’ll use the same treatment again with a lice comb!

19 Essential Oils Proven to Repel Head Lice

12 million kids will get head lice this year. How can you be sure that your child isn’t one of them? Repel lice with essential oils.

12 million is a staggering number; it’s almost 4% of the total population of the United States! With so many ways lice can get into your home, though, it’s a wonder this estimate isn’t much higher. Fortunately, there are many useful prevention strategies that can help your kid avoid becoming one of these 12 million, including a science-backed approach featuring your favorite essential oils.

Head lice are like sharks…

Lice have a keen sense of smell and they are attracted to human blood, just like sharks and mosquitoes. They can also smell when blood is near.

When lice smell a new yummy head, they instinctively want to get there and begin their feast. This is why lice spreads to so many unsuspecting individuals.

However, the good news is.

As it turns out, you can use lice’s keen sense of smell against them. Because lice are so sensitive to smell, they will instinctively run away from any scent they don’t like. Believe it or not, your secret weapon lies in essential oils—the same essential oils that smell amazing to you. If you have these scents in your hair or on your head, quick as lightning, lice will run the opposite direction to get away from you.

Even though lice hate these scents, these essential oils smell wonderful to us humans. Essential oils like this are called lice repellents or lice deterrents .

What Are Essential Oils?

Essential oils are highly concentrated plant extracts that may be used for a variety of reasons. Over time, essential oils have been used for dozens of different purposes, ranging from healing to repelling bugs, including lice.

Are They Safe?

Just because essential oils are natural and made from plants does not necessarily make them safe to use on children. Misusing essential oils can cause burns, skin irritation, or even poisoning.

Some essential oils on this list, like cinnamon and peppermint, can irritate the skin, and others like Eucalyptus oil can cause respiratory or CNS problems on young children. You should also know which of these oils your child may be allergic to and avoid using them.

I have attempted to indicate which oils should not be used on young children, but when you create your own essential oil blends, you use them at your own risk. Every person reacts differently to essential oils, and children are especially susceptible to adverse reactions.

DIY vs Tested Lice Prevention Product

For those that do not own essential oils, jumping in may seem daunting, but it doesn’t have to be. For the DIYer I recommend Barefut’s Essential Oils. Barefut’s essential oils are 100% pure, affordable, and GC/MS tested (quality and purity). As an added bonus Plant Therapy is not a MLM company!

If you are not a DIYer, there are many lice prevention sprays and shampoos made from essential oils that are already on the market and have been tested for both safety for use on children and effectiveness against lice. You can learn the ones I recommend here.

Essential Oils for Lice Prevention

Single Essential Oils vs Blending Oils

Any single essential oil from the list can be used as a lice deterrent by putting 20 drops of essential oils in 6 oz of water with 1 oz (or 2 Tbls) of carrier oil. However, your BEST lice prevention technique comes from blending multiple lice prevention essential oils together. Here are 19 unique lice prevention blends (bonus: these scent combinations are absolutely heavenly):

**Essential oil that is not a lice repellent.

Carrier oil : To decrease irritation to the skin and scalp, I recommend using a carrier oil with any mixture you plan to put in a spray. Carrier oils that are great for hair are fractionated coconut oil, sweet almond oil, argan oil, and jojoba oil. (In a pinch, you can also use olive oil.)

Neem oil : Neem is a vegetable oil that has serious lice fighting properties. Adding one teaspoon of neem oil to any blend will pack a major punch against lice. The trouble with neem oil is that is smells awful (yes, even to humans), but you can mask the scent by combining it with essential oils.

Fractionated Coconut Oil : There is one study that shows that coconut oil has some lice preventing qualities. Fractionated coconut oil has the same lice fighting properties as standard coconut oil; the difference is that it remains in a liquid state, even in cold temperatures. However, regular coconut oil is not ideal for putting in lice prevention products because it becomes solid at room temperature. If you want to put ordinary coconut oil in your lice spray, you’d need to warm it up every time you use it so the oil melts… No thanks.

How to Make Your Own Lice Spray for Hair

For a full tutorial on how to make your own lice spray, lice shampoo, hair spray, detangler, or lice prevention house spray, check out my article 11 DIY Lice Prevention Sprays & Shampoos that Repel Lice Naturally. Below, you will find a quick guide on making a basic lice prevention spray.

Simple Lice Prevention Spray from Essential Oils


8 oz spray bottle

6 oz of distilled or purified water (Or 5 oz of water/1 oz of Vodka if you’d like it to last longer)

2 Tablespoons of carrier oil such as fractionated coconut oil

Your favorite Lice Prevention Essential Oil Blend (list above) or 20 drops of a single essential oil

1 tsp of neem oil (optional, for added protection)

  1. Combine ingredients in an 8 oz spray bottle.
  2. Shake vigorously.
  3. Spray every day in hair for lice prevention, shaking vigorously before each use.
  4. Replace every 1-2 months (this is for bacterial reasons; you can replace less often if combining with vodka)
  5. Have fun trying different lice prevention essential oil blends!

Tea Tree Oil for Lice Prevention

Tea tree oil (Melaluca) does repel head lice. However, using tea tree oil alone as lice prevention is a mistake. I see hundreds of people in my salon who have been using tea tree shampoo for years, yet still wind up with head lice. Tea tree oil alone is better than not using any lice deterring scents, but it is not adequate for preventing lice on its own for most people. You are much better off using a variety of essential oils proven to ward off head lice.

Keep scrolling for the full low-down on each of the essential oils in this article. Below, you’ll find information about each essential oil and the studies it has had with lice.

Lice Repellent Essential Oil Studies, Scents, and Products

Neem oil isn’t actually an essential oil; it’s a vegetable oil from Asia, but since it is an excellent lice repellent, I’ve added it to the top of the list. Neem oil has proved extremely effective against lice.

The major downside of neem oil is that it smells awful.

I recommend adding neem oil as a lice repellent in small doses. Adding a teaspoon of neem oil to an 8 oz lice repellent spray with lots of other scents will add a lot of lice protection, and the unpleasant scent will be covered up by the other fragrances.

Scent: Unpleasant, garlic/nutty

Studies: A 2012 study showed Neem oil and Eucalyptus oil together was far more effective against lice than pesticide products.


Scent: Think candy canes

Studies: In three separate studies, peppermint oil has proven to be among the top lice repellents, which is why many lice prevention lines use it as their main lice deterring ingredient.

Blends well with: Eucalyptus, Geranium, Lavender, Rosemary, Tea Tree oil.

Caution: Peppermint oil should be used with caution with kids under 6 years old as it can in very rare occasions cause trouble breathing. Additionally, peppermint oil can irritate skin.

Tea Tree aka Melaleuca

Citronella or Geraniol

Part of the mint family, a study comparing 54 essential oils showed effective against lice, but I have not included them in this list due to toxicity.

Was shown effective against lice in a comparative study of 54 essential oils, but not included in this list because it is carcinogenic (linked to cancer).

Was shown effective against lice in an alcohol solution, but not included in this list because of skin irritation and irritation to mucous membranes.
