Castor oil is great for thickening and regrowing hair, eyelashes and eyebrows

  • Pin It

Castor oil is often overlooked for its benefits for the skin and hair because of its extremely thick and sticky consistency.  However, if you’re looking for a cheap, natural remedy for several common skin and hair complaints, then castor oil is definitely worth your time.

Castor oil for regrowing and thickening hair, eyelashes and eyebrows

I first stumbled on castor oil as a remedy for regrowing thin eyebrows. I had over-plucked my brows back in the nineties when it was the hip thing to have pencil thin brows, and they never did quite recover.  It became necessary for me to pencil in the “bald” spots and I missed the natural look of real hair where these spots were missing.

I read about castor oil as a remedy for thinning brows and hair, and thought I’d try it. I bought a hexane free, organic and cold pressed castor oil and started applying it to my eyebrows every night after washing my face.  After about three months, I noticed my brows were noticeably thicker (and they seemed to be growing in darker as well), and attributed it to the nightly application of castor oil.

I’m not the only one that this has worked for.  So, why would castor oil help you regrow hair – both on your head and the other two important places, the eyebrows and the eyelashes.

Castor oil is high in ricinoleic acid.  This acid is a very effective natural anti-bacterial and anti-fungal agent.  This can help keep any fungus or bacteria from inhibiting hair growth.  Since the oil is also very thick, it may help to prevent hair loss simply by helping to coat the hair and protect it from falling out.

Castor oil is also high in omega 9 fatty acids, which are nourishing to both the hair and the follicle, as well as the surrounding skin.  Castor oil has a unique ability to be deeply penetrating, and this helps it to deliver its nourishment deeply into the pores and the follicles that produce hair.

It also has a high gloss, so it lends a lush glossiness and shine to the hair. A little goes a long way, and it is best to only add a tiny bit to the very ends of your hair instead of putting it up near the scalp if you’re just looking for a natural hair smoother.

Simply put about two drops on your hands and rub, then smooth through the ends.  If you use too much, there is a fine line between subtle shine and a heavy greasiness so go very light until you figure out the amount that works right for your hair type.

If you’re looking to regrow the hair on your head, you can use castor oil as a scalp treatment. However it can be tricky to get on the scalp without thinning it out with a lighter oil. You can add some melted coconut oil, apricot kernel oil or another lighter oil to help get it spreadable enough.

If you’re simply looking to help thicken hair that is thinning at the edges of your hairline, you can use pure castor oil, with a light hand of course.  Another use is to apply the oil to eyelashes to help thicken and strengthen them, as well as to help prevent thinning and shedding.

Castor oil for scar tissue reduction and shiny, smooth lips

Many attest to the wonders castor oil offers for keloid types of scars and other scars that involve a lot of hardened scar tissue.  This is presumably due to its ability for deep penetration through multiple skin layers.

Because castor oil softens the skin so much, the thought is that this softening helps to break down deep scar tissue so it may be smoothed out.  In addition, castor oil has shown promise as a white blood cell stimulating agent.  Studies have also shown that castor bean oil helps reduce the inflammatory response in subcutaneous tissue.  This may be why it seems to speed wound healing, and may also contribute to its ability to reduce scarring more quickly.

Castor oil is also excellent for the lips.  Our lips needs constant protection against the elements. Although our lips regenerate and recover quickly, they also dry out and begin to peel when they are dehydrated.

Castor oil not only smooths the lips with fatty acids, but it also helps protect them due to its naturally thick and immovable nature. In other words, it doesn’t budge without being wiped off. It also imparts a natural shine to the lips, which makes it ideal for both improving the appearance and health of the lips.

Danna Norek is the founder of, which offers a line of natural body, skin and hair care products. The Herb Mint Citrus lip balm uses castor oil as one of the primary ingredients to add shine, moisture and protection to the lips (all naturally flavored).  Line also includes a Natural Shine Enhancing Shampoo (sulfate free), Deep Hydration Conditioner, natural deodorant and a popular MSM and Vitamin C Face Cream.

      My hair was so damaged that i actually had to take clippers to it and ended up with a burr and my hair used to grow fast but it's barely growing now so i can't wait to try this and hope it works!!!

      my daughter had severe thinning hair.. (she is 19).. she was born with lush thick hair.. I read somewhere about this castor oil.. so for 6 months, she has been using it and her hair thickened up again.. and the semi bald spot in the crown of her head has disappeared.. due to the thickness of the oil, she puts a tablespoon in a little bowl and then adds a tablespoon of olive oil (any good oil can do) to thin it down.. then rubs into her scalp twice a week and leaves on 1 hour, then goes and shampoos as usual. I thought this was just another crock remedy, but it has worked for her..

      1. Carla

        that kinda sounds like me. Ive been dealing with hair loss since I was 15. I'm 21 now and its gotten worse. I've tried a lot of things. I guess, since it worked for your daughter, I might as well try it out! Thanks!

  1. Ju

    Thank you for this great info. You didn't tell us how to use it in your hair, as in, how long do you leave it on and before or after wash? Can it be left on all on & so on? Thanks

      Do a google search like 'castor oil for hair' or 'application of castor oil on hair' or even 'uses for castor oil'. It is quite messy, sticky so trying to wear it to bed would be difficult. More like apply, sit down and watch a good movie and hit the shower.
      You can also use coconut oil on your hair to soften and stimulate hair growth. good luck.

      1. Mintee

        dilute the oil down with another essential oil.. use a tablespoon of castor and a tablespoon of other.. I use olive oil.. massage into scalp. leave on an hour, then shampoo.. do this twice or 3 times a week

      Put on only at night. Does not hurt the eyes. I have tried it. Whether it worked for me or not is beside the point. What works for one may not work for another and vice versa. Won't hurt to try as long as you make sure you get the good castor oil and not junk.

    2. jfelfin

      You put it on overnite and I put one half of a panty hose leg over my head and face to keep it off my pillow. Then you wash it out and wash your hair the next day.

      You couldn't possibly put it on and then try to put mascara or eyebrow pencil over it.

      My elderly mother's eyes are very dry, and her ophthalmologist (eye doctor) gave her some drops to put in her eyes at night. Turns out, the drops were 100% pure castor oil. Not only does castor oil NOT hurt the eyes, it actually helps them!

    4. Patti

      castor is fabulous for eye health. When my son was little, he got a lot of pink eye…that is until I learned about castor oil. Then every time there was any hint of eye trouble, I'd have him lay down, put a dollop of castor oil on his closed eye and cover it with a hot/warm damp washcloth for about 10 minutes or so and never had a problem again. It's wonderful stuff!

    5. toni

      To answer Myrna or anyone about how to put it on, I would use a clean mascara wand (I always completely clean & save the good ones for things like this). How is everyone else doing it?

  2. Chris

    I made an oil face wash of grape seed oil and castor oil. The castor dries out oily spots while the other oil nourishes the rest of your skin. It was working like a charm for me, time to start using it again! By the way, you could also use coconut oil, olive oil, or any other natural oil that suits your fancy. Just need to adjust the castor according to your face's oiliness. If it dries it out, less castor, if it seems too oily still, add more. My ratio is about 3:1.

    My husband had a growth about the size of a dime high on his cheek and in front of his ear and it was growing. I told him to rub castor oil on it every morning and at night before he went to bed and in about 6 months it totally disappeared…you could not tell a growth had ever been there. Needless to say I'm a firm believer in the benefits of castor oil. If you want to learn more about all the benefits of castor read: The Miracle Oil: Secrets of Edgar Cayce's Palma Christi Revealed.

      I had a small patch of skin on my forehead about the size of an eraser on the end of a pencil where it was a harder texture, a little darker, and slightly raised. Over the years it became more prominent, so each night I applied a dab of a paste made from castor oil and baking soda, and sealed it with a small piece of saran wrap. The spot would become red, softer, dry, and a layer would flake off or could be rubbed off. After a couple of months the spot was totally normal; I could not tell where the patch had been. This works on moles as well.

    External and home made remedies are good for your hair. Unless you experience some problems which require medical treatment. Your hair often indicates the state of your whole body. That is why hair problems should be first of all treated from inside out. I have strongly suffered from hairloss over years. No external solutions could help. The thought that crossed my mind is that the issue cannot be tackled externally. So I started googling up pills and dietary supplements for hair loss conditions. There are at least 30 products sold on the Internet that are designated as hair loss products. Their price range is also very diverse: from very cheap to very expensive. The product that caught my attention was called Hairgain formula (90 capsules) by Military Grade Nutritionals. This product is the only nutraceutical which possesses prostaglandin D2 blocking properties.In about three weeks of using it, I noticed that my hair got back its natural shine and hair strands got thicker. My skin condition improved significantly. I also became more relaxed. Highly recommended product, guys.

    I live in chennai,i had a heavy i heared about castor oil half ratio with coconut oil promotes hair growth,yeah it does work but adding few herbs made it more effective.massaging is important.And diet like almond,walnut,black dates,indian gooseberry makes a man's life even more healthy and energetic.

    Ricinus communis…is a poisonous plant. It's seeds especially. Ricin gas (nerve gas) is made from it, too. Wouldn't touch the stuff with a ten foot pole. Coconut oil is better. growths which respond to it's application may not be cancer but fungal in origin. Check this out in more than one place people. Be informed …be careful.

    1. Vidya

      No, i don't agree with you. Main source of castor oil is India. I grew up in India and we plant it in our home and the seeds which are dry and fall from the plant is not poisonous. we use one are two seeds in our cooking also.

      Since eye doctors give castor oil for use INSIDE the eye (applied on the front of the eye, not injected or anything like that), perhaps the swelling was from contamination which got into your eye while applying the castor oil. Same as the risk of eye irritation and swelling from contamination when inserting or removing contact lenses. If you're very clean and know how to avoid contamination and are sure that wasn't the problem, perhaps it was the type of castor oil you used. Purity is VErY important, especially when using it in or around the eyes.

    While hair sparseness is a harming physical trouble, those encountering it are seen to endure pulverizing mental impacts too. These unfriendly impacts are regularly because of the troubling, disgracing and baffling nature of the great male pattern baldness. This uneasiness for the most part assumes an extraordinary part in the choice to search out hair sparseness cures. It is a urgent endeavor to restore some feeling of self-esteem around the individuals who have lost all fulfillment in their self-perception.

    i have been using since two month this castor oil to stop hair fall and regrow the hair again . but did not see any benefit from this oil tell me why pls

  9. Jacob

    Really a nice one..When I read this one I started searching in about this oil. And I found like the Castor oil is nothing but a vegetable oil which is obtained from the seeds of the castor plants like Ricinus. And it is mainly used as a food additive and reports says like it is started using for hair loss prevention. Really want to try this oil. But I don’t know where I get this one.

  10. muskan

    from where i will get this product. i am using neuzen herbal oil but my hairfall is like before not a single change. is it really working? do i need to switch?? please reply .so much hairfall.

      A large percentage of people have a zinc (mineral) deficiency, which can cause excessive hair fall and scalp problems like dandruff due to overgrowth of yeast. I started taking zinc picolinate 44 mg. (body ready form) recently and my hair loss went from profuse to what I would say is normal.

    ciao everyone Not all oils are the same meaning that you have to make sure you are getting a castor or any other for that fact oil that is from a good natural organic state one that is not old and rancid. This is true whether using on or inside the body. So this may be reason some are using the castor oil & not seeing results. I am very clear that working from the INSIDE out IS the Key. So put IN your body HIGH dense nutrition and if you want to put those same things outside on areas needing help then this is GOOD* Remember EVERYTHING you put on the body goes into the body. Our skin is our largest organ of the body. Take a look at the crazy ingredients that are in most of the products on the market & you will see why people are having so many issues health wise*
    hope this helps

    Also try getting argan oil, the one from the Pro Naturals brand is awesome to grow your hair strong and healthy. They have shampoo and conditioner too. You can get them online. Best stuff I've used. :)

    hey my mom told that castor oil applying at night time and washing like coconut oil in morning is not good it would make headache is it true help me please

    1. Jessica

      Hormone changes due to low estrogen levels will cause hair to grow slowly
      Answer your question: I have used organic, pure coconut oil sold at Walgreens for $10.00.
      in the vitamin section. It's made by Spectrum a popular brand sold in grocery store chains.
      I'm in my late forties and Caucasian. I have thin,curly hair; I dry it straight and color it every 6 weeks.
      I apply it all over my scalp, and massage for 5 minutes.and place it all over my hair. Wash it first!!! Let it Dry naturally, I seep w it and keep it on for 12 hours. I sleep on my stomach. Once or twice a week is enough.
      You can put a shower cap on if needed.
      The next day rinse w water first and than a conditioner, some people may need to shampoo first.
      Other option: sit under a commercial dryer, used in salons, at home.The cuticle will not ABSORBE anything after 10 minutes. <<<use a shower cap
      My hair is so silky and soft. I used a dab on heels and hands works like a miracle.
      I will never buy any commercial lotions again. Never buy anything w petroleum, sulfate, or para-bens
      Added a zinc and copper supplement sold at the vitamin shoppe, absolutely LOVE THIS STORE!!!
      Inside is just as important, if not more important, than the outside

    2. Jessica

      Also, coconut oil has a very light, scent, but you can't smell it..
      I have never used castor oil, but I am going to try it on my eye lashes w an applicator, disposable brushes.
      I'm excited about using the castor oil on my eye lashes, because of hormone changes, my eye lashes have thinned out a bit.

    Thank you for an interesting article. l would love to try this hoping to restore eyebrow hair loss, but have been told that loss of eyebrow hair, especially in the last part of the eyebrows, if often due to incorrect hormone levels in the Thyroid Gland – either too little or too much! Can you comment on this please?

  15. Lucy

    Fascinating. Thanks so much for this article. I've had alopecia for 24 years. My eyebrows have gotten thin which really bums me out. And I've had to wear a scarf on my head for a great amount of the last 24 years. I just found a diet that is helping a lot, so this is very complimentary to that. Can't wait to try–and hopefully renew.

    I have very long colored hair that gets dry at the ends. I rub the Shielo Restoration Oil into wet or dry hair and the ends of the hair are just as supple as the hair at the roots. Plus, I am very, very tender headed and this Shielo Oil makes comb out easy-peasy.

    U can get good castor oil almost anywhere online if u can't find it in a store near u. Just make sure that it it of great quality! Make sure its therapeutic grade. My mom used to make me take a tablespoon full when I was constipated as a child….it didn't kill me! But tasted so bad that I prayed it would kill me!!!! Lmao. I have not tried castor oil for hair but I will get some tomorrow at our health food store….if they are very good quality!!!! They don't cary therapeutic grade essential oils so I'm not expecting them to have it here in my town….but in the next I know there is a cvs….Or I can order something online. Does anyone know if it helps for hair fall that's caused from meds??? I hope u ALL have great results from this….I'm starting asap.

    Castor oil has been in use for in India for many many years. Yes it indeed, helps in hair growth and is also used as a purgative. But all ladies out there, be careful, youwill end up with your beautiful face full of unwanted hair growth.
