Tea Tree Oil For Head LiceHave the head lice been bothering you for a long time now? You are not alone. Millions of people especially 25% of school-going kids are affected by head lice every year.

Head to head contact, using things of an infected person are the main reasons of head lice spreading from one person to another.As head lice reproduce and mature very quickly it is impossible to get rid of them in a single sitting. They can survive in wet hair and don’t get washed out as they stick tightly to hair strands.

A great deal of money is spent on chemical treatments for head lice.  The worst part is – head lice have become resistant to most of the chemical treatments available in the market. Also the ingredients present in these treatments are neuro-toxic. If you want to know more about the dangers of chemical lice treatments click here.

Instead of resorting to such treatments, trust natural ingredients like tea tree oil, rubbing alcohol, neem oil and mayonnaise to treat the head lice without any side effects.

Here, let’s learn about – how tea tree oil or melaleuca oil helps to kill the head lice, how to use it and other precautions to take care off. Read on…


Does tea tree oil kill lice infestation?

For Head Lice: Tea tree oil contains two major elements – 1, 8-cineole and terpinen-4-ol. These two elements have insecticidal properties due to inhibition of acetylcholinesterase. (1) 1% of tea tree oil solution is found to combat head lice by 100% with the time of 30 minutes. (2)

For nits or lice eggs: The nits are strongly attached to the hair shaft by the mother head lice. The gummy texture that connects nits and hair shaft is very strong. This gummy texture will be dissolved by the application of tea tree oil which makes it easy to remove while combing.

As per a study published by Parasitology research states that Tea Tree Oil can kill head lice in both nymph and adult stages. And it also showed promising results in preventing the eggs from hatching. (3)

For Re-infestation: The strong smell of tea tree repels the head lice from transferring from one to another. This is very helpful in preventing the infestation when a person or child in your house or class is already affected by head lice.

As per the study presented by International Journal of Dermatology, tea tree oil has shown results in repelling lice. (4)

These are real time experiences from our readers which worked for them. Remedies explained in detail after these comments

Verity says
When my daughter was three she had caught lice and she had it for almost a year. I treated it three separate time with rid and nix and so forth. I had also tried coconut oil, olive oil, mayonaise. Nothing worked. I use a lot of tea tree. But, I poured like one third of a bottle into maybe half a cup of conditioner. Slathered it onto her head and then wet her hair in the morning and combed it out. The lice was gone in one day. She caught lice again when she was 8. Did the tea tree method, gone in one day. She is 9 and got it again last week. Did the tea tree method. Gone in one day. I want to let every frustrated and crying mother at their wits end to know about this. It should be more common knowledge.


Heather says
I poured some cheap “Suave” Conditioner into a bowl, did about 10-15 drops of tea tree oil into the mixture, lathered it onto wet hair and took the comb to it. It was very simple! After we were done combing I rinsed my hair out and repeated that process every other day until I saw nothing left in my hair. I also followed your spray advice and almost every day I have been spraying my house down, furniture, sheets, towels, etc.
I added tea tree oil into all of our shampoo & conditioners too!

  1. In method 2 for removing nits do i apply to dry or wet hair. And I’m using a tea tree oil conditioner along with the 5 drops, is that a problem?

      1. Not true. Dogs get lice just not the same as our lice. But they do look and act the exact same as ours.

  2. When my daughter was three she had caught lice and she had it for almost a year. I treated it three separate time with rid and nix and so forth. I had also tried coconut oil, olive oil, mayonaise. Nothing worked. I use a lot of tea tree. But, I poured like one third of a bottle into maybe half a cup of conditioner. Slathered it onto her head and then wet her hair in the morning and combed it out. The lice was gone in one day. She caught lice again when she was 8. Did the tea tree method, gone in one day. She is 9 and got it again last week. Did the tea tree method. Gone in one day. I want to let every frustrated and crying mother at their wits end to know about this. It should be more common knowledge.

    1. Verity I am dealing with my kids and the same situation you had. How many times did you treat their hair with the tea tree oil per day before it was gone?

    2. I have been going crazy between two 11 year old girl. My daughters have lice, and i have tried everything every type of lice treatment. Going to go get this Tea tree oil.

It seems I have read some where there is a mixture that be sprayed on clothing and bed to limit the chance of him getting th again can some one help? I love tea tree oil I use it for many different reasons. Please help my friend Thank you

          1. Yes, the diluted tea tree oil solution can be sprayed on the infested head to treat the infestation and prevent it as well. For a detailed step-by-step process, you can read 2nd method mentioned in the article.

        1. will the smell be noticeable?is it harmful to someone to sit on furunuiture or carpet after spraying tea tree oil please help im desparate tried everything including expensvie meds

  3. Where could I get it?? And does it matter what kind of tea tree oil there is so many I have no idea what to choose from HELP!!

    1. You can buy at any local store or online stores like Amazon or Walmart. You can buy 100% pure Australian essential tea tree oil. Some of the best brands you can buy in USA are doTERRA, Young Living, Plant Therapy and Eden’s Garden.

  4. Can I always leave Tea Tree in her daily shampoo and conditioner ? So every day she has it in her hair. Is ok. Can I use lavender to help keep them away.

    1. Yes, you can mix and store it. Make batches every week instead of storing a single batch for more than 2 weeks. Tea tree oil works better than lavender oil.

  5. I have an adult 28 year old daughter and a 16 year old daughter. The oldest brought headlice home from her job , never told us . Now we’ve got super bad add odor and can’t get rid of it. I’ve even used tea treeoulshampoo n conditioners and it is still not gone ,have also used olive oil and white vinegar ,& lice killing shampoo. Please somebody help me what else can Ido?

        1. There is no need to cut off the hair. Try any remedy mentioned above. If the head lice don’t go even after the several treatments and if there too many nits, then you can cut the hair.

    1. Tea tree oil is very harmful for dogs if it is not properly diluted. So dilute tea tree oil in large amounts of shampoo before you use it on dogs.

  6. can tea tree oil be used around cats (as in using the spray bottle with water and tea tree oil to spray on beds, couches, etc.) we have 2 grown cats

    1. Tea tree oil is safe for cats only if it diluted properly. Make sure tea tree oil is not ingested by cats as it can be very dangerous.

  7. I read this looking for a way to prevent getting lice in the first place. If tested to see about reaction can this be sprayed on and left on during the day?

      1. If I add to shampoo can I add it to conditioner as well? And does it have to sit on for so long before rinsing? And also should I have them wash their hair every day with that being added in the bottle of shampoo or is every other day still OK as we do. * Preventing not treating*

        1. As you want to prevent the head lice infestation, you can just rinse their hair once in 2 days. You can add tea tree oil in shampoo and conditioner but make sure to reduce the quantity you add into them. If they don’t have head lice then it is not required to sit for so long.

    1. Apply coconut oil or olive oil on the scalp and along the hair. Put on a shower cap and leave it overnight. Next morning, comb the hair. Make sure the comb has soft bristles. Give a head bath with baby shampoo and water.

      1. I wouldn’t recommend putting a plastic bag on a baby’s head as it can easily slip down and suffocate the baby overnight. Actually, there are cases where mothers have had that exact thing happen by mistake. Better to do it during the day while you can supervise 100% of the time.

  8. Thank you so much for this information .. My daughter caught head lice recently and I made the tea tree coconut oil shampoo for our whole family. It worked really well and all the bugs on her scalp were dead. I combed everyone’s hair with the not comb, although she was the only one with evidence of lice.
    Tonight I checked her hair again and I see new nits. We must’ve missed one egg and it hatched and we are starting again.
    I am thinking about making a tea tree spray to apply to her scalp nightly, or every other night to kill the nits (in case we have any stragglers this time). How do you recommend I create this? Should it just be straight tea tree oil? Or can I mix it with something? Thank you again for your knowledge and support.

    1. Dilute tea tree oil with enough amounts of water. Mix well and pour into a spray bottle. Spray on her hair before going to bed and rinse off next morning. Make sure to dilute it properly or in more amounts of water as sometimes improper dilution can lead to burning sensation on the scalp.

      1. I thought u couldn’t mix oil with water I’ve read many sites that say water and oil don’t mix…is that true?

        1. Water soluble tea tree oil mixes well with the water. You can purchase it in any local or online stores. If you don’t have water soluble tea tree oil, then you can mix the oil based on with any carrier oil like olive oil, almond oil or coconut oil.

  9. I just found out tonight I have lice I got it also from work I used tea tree oil with shampoo then while my hair was still wet I did a conditioner with tea tree oil in it an left it in my hair for 30 mins but I have a question is my scalp supposed to feel like its burning ? I did rinse out the stuff once the 30 mins was over but why is it still tingling an a burning sensation ??

    1. As per your description we are unaware of the quantity of tea tree oil you used. Improper dilution of tea tree oil can lead to burning or tingling sensation. So, next time whenever you use make sure to dilute it more with shampoo/conditioner. If you are not able to withstand the burning sensation, apply aloe vera to the scalp you will find relief.

  10. I made the spray (10 drops with 2 cups water) planning to spray furniture, carpet, bedding etc. we have 1 cat and a Guinea pig – are there any concerns with spraying this in the home with them?

    1. Diluted tea tree oil is considered safe and well tolerated by cats and guinea pigs. But dilute it in more amount of water. 10 drops in 4 cups of water should be safe for them. Avoid their presence while spraying the solution. After 30 minutes of spraying, allow them into the room.

  11. I have the Hollywood beauty tea tree oil….will it harm my 14 year old daughter if I don’t dilute it,and put it on straight out of bottle?

    1. It is better to patch test before trying out complete treatment. Undiluted tea tree oil can cause irritation, burning sensation and redness. If it is not causing any of them you can apply it directly. But we recommend diluting it properly to avoid any consequences in future.

  12. I want to put the tea tree oil in my daughter’s shampoo, how would you recommend I do this? How many drops per bottle? Conditioner also..

    1. Add 10 – 15 drops of tea tree oil into 2 cups of water and pour the mixture into a spray bottle. Shake well and spray it on your furniture and hairs.

  13. I want to spray our house and also use as prevention. We’ve dealt with lice 3 times this year, twice in the last 4 weeks! I’m 31 weeks pregnant and we have a small dog. For the dog, should I spray then let him come in after a half hour, after its dried? As for me, if I dilute it properly in our shampoo and conditioner, what are the risks?

    1. Yes, allow your dog inside after 30 min to an hour after spraying. It is safe to use tea tree oil dilute in shampoo and conditioner for pregnant ladies. So don’t worry but make sure you don’t ingest it by any means as it is highly toxic when consumed.

  14. Thank you SO much for the great advice. What an amazing oil!! I have two daughters who attend a school and head lice is going around like crazy. I am trying to prevent it. We followed your instructions for shampoo and conditioner, but can I use the diluted spray (10 drops to 4 cups water) to lightly spray their hair in the morning, after I put it in buns or braids? Or would you not recommend that? Again, thank you!

    1. Yes, you use diluted tea tree oil spray to lightly spray the hair. It helps to prevent and stop spreading of the head lice infestation.

    1. Yes, it is safe. But if it is causing any redness, irritation or other discomfort then reduce the amount of tea tree oil.

  15. I had head lice a week ago and treated with Mayonnaise and tea tree oil. It killed the lice and I removed with comb. Two day prior, I seen a Dermatologist with numerous itch bumps. She didn’t say anything about lice and I had went to ER 5 months prior so I had itch shampoo and Itch pills which didn’t help because I didn’t realize I had lice. It has been seven days since I treated with Mayo and tea tree oil. Last night my scalp started itching so I sprayed tea tree oil and left over night. I now have Mayo in hair with shower cap and tight bag. The first treatment I left on for 4 hours. Do I have to leave it on that long this time. I know mayo doesn’t kill egg but tea tree oil does. Mayo and Tea tree oil has worked wonderfully. I have treated my home and linens and bagged what I couldn’t wash or dry. What is my next step. Thank you for any advice.

    1. You can leave the application as per your convenience. If it is causing any discomfort then leave it for lesser time. Generally, we suggest leaving it for 4 – 8 hours (for adults). Repeat the process regularly for 2 times a week. Once don’t have any head lice, stop the process.

  16. I have gotten head lice from somewhere,somehow. My question is if I use the spray mixture. With 10- 15 drops of tea tree oil. How many times vs it be applied in 24 hours also would it have to be showered off between applications. Will it be strong enough to enough to kill both lice and nits? Thank-you and God Bless all.

    1. You can spray the mixture before going to bed and leave it overnight. Brush your hair thoroughly and wash normally with shampoo and water. You can also add few drops to your shampoo for extra results. Yes, the mixture is strong enough to eliminate lice. But don’t forget to repeat the process regularly.

  17. Is it normal for your head to hurt I put the tea tree oil, coconut oil and water in a water and spayed that in my head and my daughter and put a cap over it we slept the whole night like that’s and ever since my head has been hurting a lot I had to even miss work

    1. No, it is not normal. As per your description, we are not sure if the headache is caused due to tea tree oil. But you can avoid tea tree oil and see if the headache didn’t come back. If it is caused by tea tree oil then avoid it and try different remedies. You can find more remedies, in this article – http://wellness.guide/head-lice/

  18. My 16 yr old step daughter brought home lice about 2 months ago and I treated her with the normal over the counter lice treatment but she never followed up as directed and she still has it and now I have it too. In fact I keep finding adult lice fall off my head, dead. Does that mean anything?? Can you email me exact directions with using tea tree oil vs the over counter stuff. Sounds like it has been more successful than the over the counter stuff! Including the spray mixture to spray everywhere we sit and sleep, etc. Thanks!!

    1. We have provided step by step process of every method in the above article. Choose any remedy as per your convenience and try it regularly. The 8th method in the article has the process of making a spray with tea tree oil. You can spray this solution on furniture, carpets, stuffed toys and mattress.

      1. Step 1. Tea Tree Oil- What would you suggest after waking up in the morning for combing? I would think trying to comb you hair after waking up would be a mess. Hair tangled up from tossing and turning!

        Let me know what your thoughts are on how I approached this. I poured some cheap “Suave” Conditioner into a bowl, did about 10-15 drops of tea tree oil into the mixture, lathered it onto wet hair and took the comb to it. It was very simple! After we were done combing I rinsed my hair out and repeated that process every other day until I saw nothing left in my hair. I also followed your spray advice and almost every day I have been spraying my house down, furniture, sheets, towels, etc.

        I added tea tree oil into all of our shampoo & conditioners too!

  19. Hi, my 5 yr old daughter came home from kindergarten with a letter stating that someone in her class has lice, and we should watch out for them. Can I mix 10-15 drops of tea tree oil in her leave in detangler? She has curly hair, and I usually spray it in the morning before brushing. Just wondering if I can prevent it that way? the bottle is about 250ml, do you think 15 drops is too much? Thanks!

    1. Yes, the spray will help to prevent the head lice. If the solution is not causing any discomfort to her then you can continue. If it is causing any discomfort then reduce the quantity of tea tree oil.

  20. If I don’t have a dropper for my tea tree oil about how many teaspoons would I need for a spray solution and how much to add to shampoos??

    1. You can add 1/2 teaspoon of tea tree oil into your shampoo and about 1/2 – 1 teaspoon of tea tree oil for a spray solution.

    1. Leaving it overnight provides more effective results. If you cannot leave it overnight, then you can leave it for 2 hours but the results would be less.

  21. I’ve done the spray treatment for about a week. Every other day for my 2 daughter’s who caught lice from school. We have been dealing with it for a while using different methods. This is my first time to use tea tree oil. When I use a nit comb on their hair I don’t see anything on the brush or towel as I wipe off between brushes. But when I’m donexcited other he combing I still see eggs. What am I doing wrong? Or what else can I do? I’m desperate.

    1. Increase the tea tree oil quantity and apply it along the hair strands. Patch test before applying to make sure it isn’t causing any irritation. See if it works out.

  22. Hello,
    I found 2 full size lice and about 5 babies on my 3.5 year old. I found them while combing her hair after a bath. I then sent hubby to store and bought an over the counter kit to treat them. I did the process on her and her twin sister, after washing, you apply a gel and comb out a 2 in section of hair doing the whole head. During that time, I did not remove any Nits or see any more lice. It says to re-wash in 1 week.

    In the meantime, I was going to treat with tea tree oil spray and/or the shampoo solution on both the girls and myself. In your experience, is this too much?

    1. It is better to use either the commercial one or natural method. As your kid is still very young their scalp cannot handle of all them. Sometimes, it can lead to skin irritation.

  23. My daughter is two years old. Today I found one live lice and 7 egss. We have been using the lice comb on her hair all day. I would like to use the tea tree oil on her head to kill eggs and or any live lice that we have missed with the lice comb. How do I use the tea tree oil treatment on her head? Also how do I make the spray to use on her head for every day use. Thank you

    1. combine 2 – 3 drops of tea tree oil and 2 – 3 tablespoons of olive oil. Apply this mixture on the scalp and along the hair. Leave the application for 30 minutes and rinse with water. Comb the hair to remove the dead lice. For a tea tree oil spray – add 1/2 cup of water and 3 drops of tea tree oil to an empty spray bottle. Close the lid and shake the bottle well. Spray the solution on the hair.

  24. If I had a 2 oz bottle of tea tree oil would it be safe to split it three ways for 2 shampoo bottles and for the home spray?

  25. You mentioned that one could apply tea tree oil to a regular shampoo, but is it as effective to buy a shampoo that already contains tea tree oil? If so, which would you recommend?

    1. You can buy a shampoo that contains tea tree oil like Tru Moroccan Repair Shampoo, Keva or Tea tree mint shampoo.

  26. I use only use tree tea shampoo and conditioner I wish more people could understand how good it is not only for lice but so much more my friends kids were just told they had lice and Im now showing her tree tea knock on wood that I can say that because we only use tree tea my family has not had any in 14 years from the first day we started using tree tea

  27. I got head lice at the beginning of this week, and i use Melaluca shampoo that contain a small amount of tea tree oil. I found lice in my hair and told my dad. My two sister have it now and we all washed our hair with a shampoo called “tea tree mint shampoo” and i washed my hair with Melaluca and let it sit, then i washed it with the new shampoo. I blow dried my hair and found lice and i still have nits. If i do this process every two days about how long do you think it will take to get rid of lice and nits completely?

    1. As per the method and treatment time, we have mentioned various above in the article with a detailed description. You can try any one of them as per your feasibility.

      1. My daughter had an infestation of lice and a very bad one, she lives in another province with her father and came down for a visit when I noticed the insane amount of nits and lice in her hair, we used Teatree oil and Teatree shampoo and mixed them together, left it for the 15 minutes used the nit comb and basically filled the sink with the pesky little critters, however they were all dead from the solution. I did the treatment a day later as well just to be sure, today I noticed a couple more nets in her hair and redid the treatment. We treated the whole family just in case, I had three lice in my hair and few nits, my question is is there a difference between a lice infestation and only having a couple? Now that I have done two treatments to my hair should my hair be OK? Or should I have to keep applying the Teatree oil as if I had a whole infestation? I’m still going to make my daughter use the Teatree shampoo without mixing it with the Teatree oil pretty much from now on LOL should the Teatree shampoo prevent her from being infested again or should I keep applying the Teatree oil into the Teatree shampoo as well?

        1. If you have just few lice then it is better to use tea tree oil shampoo for few washes just to make sure they are dead and don’t produce more leading an infestation. For your daughter as well, we recommend using tea tree oil shampoo regularly to make sure she doesn’t get head lice again.

  30. My son, who lives with a bunch of other people came to visit me for my Birthday, haven’t seen him in 2 years. While he was here, he barrowed our car to visit some people he knew in this area. I tell you that, to tell you this. He had spent some time in my bedroom watching my TV, laying on my bed. Well after he left I started to itch, feels like something crawling over my fine body hairs. Asked him about these friends and if they were clean, he said no they weren’t doing so well and were rather dirty. So I am wondering what he brought into my home. I have some bites, but not bed bug type bites, just bites here and there, my head it itchy. Asked my husband if he is okay, he says yes. But I have seen him scratching a bit as well, but you know how men can get. Asked him to look in my hair, says he saw nothing. Next thing my ear plugged up so bad with something, I went to Urgent care, they found a wad of something in my ear (white and creepy) they didn’t know what it was. So I have been all over online and the only things that seem to match what I feel is going on is body lice or scabies? Guess I won’t know unless I go to a dermotologist. But in the mean time, willing to try the lice thing to rule it out maybe? So bottom line is can I use tea tree oil on my body? And if so, what would be the best way and soak time etc? Thanks in advance.

    1. : It is better to know the reason for the discomfort before you try any method. For relief, you may soak in lukewarm water for 15 – 20 minutes.

      1. Thanks for the reply.

        I did the tea tree suggestions all over my body, been doing bedding, towels in hot water and drying for ever, hosing down couch and chairs with solution of tea tree. Feeling a bit better, think i will continue for a bit and see how that works out for me. Sure is tough when you feel you can’t invite family for a visit 🙁 Wish me luck!

  32. After you kill or subdue the lice with tea tree products….
    – you MUST carefully comb out all the nits (eggs) with a good nit comb or they will continue to hatch every few days. This takes about 1-2 hours per head since you can only do 1-2 square inch at a time gently scooping up and away from the scalp. (Wet hair strands with a tea tree water+conditioner works best)
    – Any items that can’t be laundered in hot water, need to be put in a corner or closet and not used for 10 days (backpacks, hats, throw pillows, etc)
    – Also vacuum carpets and sofa.
    – Combs and hair accessories can be strilized by leaving them in your freezer overnight.

  33. i bought a bottle of hydrating tea tree mint shampoo …..will this kill lice……or do I have to buy the oil to mix into, my shampoo……and if the purchased shampoo will work……then how do I apply this to my 15 year old daughters head
