How to Use Jamaican Black Castor Oil to Regrow Your Hair

Can Jamaican black castor oil actually help regrow hair and stop hair loss?

My research led me to hundreds of testimonials from people who have used castor oil or Jamaican black castor for hair growth – 3-5 times faster than the normal rate.

I also found studies that back these amazing stories.

In this post, you’ll find how castor oil helps regrow hair, the key component responsible for this, and exactly how to use black castor oil to stop hair loss and promote new hair growth.

How Does Castor Oil Help with Hair Growth?

Castor oil has strong antibacterial and antifungal properties and is high in minerals, proteins, Vitamin E, and Omega 6 fatty acids.

The extremely high ricinoleic acid ratio is the key to hair growth and hair loss prevention, by keeping any fungus or bacteria from inhibiting hair growth.

Centuries ago, the plant was referred to as “Palma Christe” (hand of Christ) because the leaves were said to resemble the hand of Christ.

Traditionally, Castor oil has been used as a laxative and topically for acne, rashes, and any skin condition.

How to Use Jamaican Black Castor Oil for Hair Growth

To make your own castor oil hair growth treatment, mix castor Oil with another hair-healthy oil (such as Coconut Oil or Argan Oil) and one or more essential oils for hair growth (such as the amazing Rosemary Oil).

With castor oil, less is more, and you’ll only need a small amount of it on your scalp to reap the benefits (especially if you have a dry scalp!)

Here’s how I make my mix, which lasts for about 5 uses:


  1. Mix the ingredients in a dark dropper bottle for easy application.
  2. Apply a few drops of the mix on different parts of your scalp until you’ve coated everywhere (use a shower cap if you have one).
  3. Massage your scalp for about 2 minutes.
  4. Repeat the treatment 1-2 times a week.

For me, the treatment works better on damp hair – not entirely wet.

Leave it on for 1-2 hours, preferably overnight (it absorbs better and less to wash off later).

To wash the oils off your scalp you’ll need to shampoo twice, preferably with a natural shampoo.

Bonus tip: To detox your hair, add some activated charcoal to your shampoo. It’ll clear all toxins and chemicals off your scalp.

( See 22 amazing health and beauty benefits of activated charcoal)

You can rub this mix on your eyelids and eyebrows if you’d like them to grow thicker and healthier (but not the Jamaican one, only the pure, cold-pressed, and hexane-free castor oil can go be used around your eyes!)

If you prefer not to make this hair treatment on your own, here’s a good product.


The Castor oil plant can be a skin irritant for some people, so test a tiny amount on your inner arm first.

What’s the Best Castor Oil for Hair Growth?

If you’ve chosen Jamaican Black Castor oil, the one above has high ratings and is very popular

If you’re using pure Castor Oil, make sure it’s cold-pressed and hexane-free.

My favorite is Sky Organics Organic Castor Oil.

Castor Oil VS Jamaican Black Castor Oil 

Cold-pressed Castor Oil is a natural oil with a pale yellow color and no smell.

The clear castor oil you’ll find in stores is the result of filtering this natural yellow oil to further lower the iodine content which makes it yellow.

The higher the purity of the castor oil the lighter color it will be.

(Read: 10 reasons to use Castor Oil on the face overnight)

Jamaican black castor oil’s black color comes from adding ash from roasted castor beans into the oil (and it does smell like someone’s been smoking nearby when you apply it on your scalp…)

This ash is an addition to the oil and not just the pure thing. Is the ash beneficial?

No science behind it, but Jamaican black castor oil is less sticky and easier to apply to your hair.

Bottom line, it’s a matter of personal preference. Some people say that the Jamaican works better, and some disagree. Everybody is different.

Pro Tip: Combine with Red Light Therapy

Did you know?

Red light therapy (Low-Level Laser) is scientifically proven to promote hair regrowth and reduce hair loss.

Combining Castor oil with a red light therapy home device (I recommend a laser cap or the laser comb) and a daily scalp massage – can make your hair loss treatment much more effective and powerful.

More Benefits of Castor Oil for Hair & Scalp

Castor oil is more than a hair growth remedy. Here are more ways Castor Oil benefits your hair and scalp:

1. Dandruff – castor oil’s anti-bacterial, antiviral, and anti-fungal properties make it a great remedy for scalp infections and issues such as dandruff from a dry and itchy scalp.

See the 6 most effective home remedies for dry scalp

– Mix 1 tbsp of pure Castor Oil with some olive oil and juice from half a lemon and apply on your scalp. Leave on for 30 minutes and wash off.

2. Natural conditioner – castor oil is moisture-rich and penetrates deep into the scalp to condition your hair.

The result is a great shine and soft hair – for all hair types.

Always mix it with another hair-healthy oil, such as coconut oil or Argan oil, and shampoo twice when you’re done.

Try this mix:

Apply to your roots and leave on for 30 minutes before a thorough wash.

How Often Should You Use Castor Oil for Faster Hair Growth?

You can safely use CO 2-3 times a week, as long as you wash it out at the end of the day.

However, you can get the same results by using it only twice a week, or even once per week, since it’s a very effective hair growth treatment.

In some severe cases, you can use castor oil daily but mix it with 50% coconut oil, since the oil can create a sticky buildup.

Can You Leave Jamaican Black Castor Oil in Your Hair Overnight?

You can black castor oil on your hair for at least 30 minutes, or overnight.

Since it’s very heavy oil, make sure to shampoo twice to ensure you remove any oil residues that may clog your hair follicles.

While you can technically leave castor oil in your hair overnight, leaving any oil on overnight or for longer than four hours should only be done intermittently, as it can lead to possible inflammation.

It is up to you to decide how long you want to leave the oil in your hair, but I recommend washing it out after treatment to prevent the heaviness of the oil weighing down the hair.

Castor Oil vs. Argan Oil 

Castor oil and Argan oil are both known to benefit the hair. When comparing argan oil vs. castor oil for hair growth, there is no clear overall winner.

While castor oil is known for helping damaged hair grow better, Argan oil is usually used as a deep conditioner or as a pre-styling product. It helps restore shine to your hair and mend split ends.

People with fine hair may have a tougher time with castor oil because it’s so thick.

If this is you, castor oil isn’t off the table. You just need to mix it with another oil to thin it before you get the results you want.

On the other hand, Argan oil is light and can be an easy and hassle-free way to improve your hair over time.


In my experience, Jamaican Black Castor Oil is an effective hair growth oil and a natural and cheap remedy for hair loss. Hundreds of people report great success with it.

Castor Oil can also be used to strengthen and thicken your eyelashes and brows and heal dry and itchy scalp symptoms.

Try to buy a high-quality Castor Oil and always mix it with another oil to reduce its thickness.

  1. African Americans don’t wash their hair daily can you apply the castor oil, say twice a week, and wash hair weekly?

  2. Meital:
    The Castor Oil Treatment, can be mixed with some aromatic herbs (for example, Rosemary) or some petals for adding a nice smell to the mix? Or if is mixed with a natural fragance could ruined it?

  3. You can use it every day as long as you wash it out well, otherwise, it may clog your scalp skin. Water is not enough to wash it off, but you can use water with baking soda to remove the JBCO without soap. If you are trying to promote hair growth for your baby – I recommend that you stop worrying, your baby will grow healthy hair exactly when it’s supposed to happen. Both my boys were almost bald until they were 1.5 years old, and now they have healthy hair.

  4. Can you use JBCO as baby’s everyday hair oil and can it be washed off with only water daily as I shampoo my baby’s hair once in a week

  5. Yes, JBCO is safe to apply on your scalp, just remember to wash it off after an hour or after leaving in it for the night. As for food grade rosemary oil, here’s one I found on Amazon: – and yes, it’s just as effective. Good luck!

  6. Hi Meital thanks for the quick reply I thought all essential oils were the same how would you acquire food-grade rosemary oil for instance and would it be as effective? also, would it be OK to just using the JBCO with the derma roller for now till I find out about the essential oils because I’m assuming that JBCO is OK for ingesting if not please advise me otherwise?

    I have through a lot of things at my hair loss over the years as I’m sure a lot of people that have responded on here have done also even tried the onion juice it stank and so did I lol not sure if it did anything but it has been reported to help with alopecia conditions caused due to stress my hair loss is male pattern baldness though I first noticed when someone brought it to my attention back when I was 27years old never really paid attention though probably in denial back then lol I’m now 47 and it has been a gradual loss over the years.

    My only regret is not looking into natural remedies more sooner than I did especially the essential oil side of things instead of using regain minoxidil because I do think it worked to an extent but if you stop taking it just goes back to what it was like before sometimes even worse that’s why I wish I new about rosemary sooner because in latest tests it has shown to be nearly as effective as regain minoxidil but now I think it is going to be a fight to keep what I have but I will certainly look into the red light treatment you suggested also thanks.

  7. It seems like a good idea, though I would use food-grade essential oils, since they will enter your blood stream. I also highly recommend, as said in the post, to combine this with red light therapy – a proven way to stop hair loss and regrow hair – in a natural and non-invasive way. Good luck!

  8. Hi just lately I have been reading about the benefits of JBCO peppermint, rosemary, sage essential oils as well all can be used in the hopes of stopping and maybe even encouraging hair growth the essential oils I mentioned have shown promise in studies to block DHT.

    So I made a mixture of coconut oil rosemary, sage, and peppermint and put it in my hair overnight, next time I will add JBCO into the mix.

    So after doing this I thought of maybe adding something else to this regimen I was thinking of maybe trying some derma rolling on my scalp then adding some JBCO and maybe a little rosemary and peppermint essential oils afterward and leave on overnight I used to use minoxidil but never really seen any great change but I know some guys on youtube were derma rolling then adding minoxidil I gave it a thought but then decided against it as it was a drug.

    So what do you think about the derma rolling idea do you think it is worth a shot obviously with the rolling it would open up the pores in the scalp with the small wounds and may allow the castor oil and essential oils to go deeper into the scalp and derma rolling is also supposed to encourage better circulation thanks.

  9. Hi, I’ve recently bought the JBCO and in just a week I have seen results, I use it as a hot oil treatment along with my hair conditioner and it’s really working fast.
    I suffer from hair loss and am amazed that after 2 days of applying the JBCO I haven’t seen my hair dropping out as much.

    Excited to see more results a few months from now.

  10. Hi Meital. Can the Jamaica castor oil cure baldness in men? What is your experience on that?

  11. Is washing out the black Jamaican castor oil a must for the process of growing my hair to work

  12. Hi,

    It is possible to mix all of them
    Castor oil + argan oil+ olive oil+ coconut oil oil + Rosemary EO.
    for not only to grow my hair and also to keep their shine and soft too?
    thank you,

  13. Karen,

    My recommended JBCO is linked to in the post. As for washing it off – yes, wash it off after at least half an hour, or after leaving it on for the night. And yes, you can use it when your hair is straightened.
    See more of the best remedies for a dry scalp. here’s my post:
    Good luck!

  14. Thank you so much for this article. I have shared it with many friends.
    I just have a few questions. I am actually of Jamaican heritage but I was born and still live in London (UK). I am 19 years old, and my hair is flat ironed about 6 times a year. I’ve been doing this for about 5 years now. But I’ve noticed that my hair is not as thick as it used to be and I do suffer from a very dry and flaky scalp.
    So because the castor oil promotes growth, thickness, and a healthy scalp I am considering giving it a try.
    However, I do not know where to start. I believe I do have quite low porosity hair.
    Which type of castor oil do you recommend I use?
    And every time I apply the oil to my scalp do I have to wash it off?
    Can I use the oil on my scalp even when my hair is straightened?

  15. You can definitely try. I would also recommend considering red light therapy, which is proven to promote hair growth via increased local blood circulation.

  16. Thank you so much for your post. I have scarring Alopecia. Do you think this JBCO can work for me? I get relief from symptoms by using coconut oil and aloe Vera juice. I wonder if I can mix all three to get my hair back.

  17. Would you say it’s better to whip up enough of the mix you make to fill the entire dropper bottle or only make it as we go? I wonder if making a big batch would cause over-exposure. Specifically, I made a batch already but I have to order a new dropper bottle like the one I have is not as good as it could be. The mix in it is good but once the new bottle gets here I want to pour the existing mix into the new bottle as well as put a new batch in the new bottle as well.

    I may just be paranoid but is this okay?

  18. I just bought two bottles of the black one today. I put it on wet hair after I got out of the shower and massaged it for a while. The front of my hair is thinning and everywhere else is thick cause I have naturally thick long hair. Stress thinned my hair. I’m hoping to see it thicken I’m only doing in on the front of my hair. My boyfriend uses the yellow one and told me about castor oil. His hair is very thick but does shed a lot. Also, he is the only one out of his brothers and father that has not gone bald as yet and he’s the oldest brother. He also told me eating meat will make you go bald. I don’t color or put chemicals in my hair. Did it a few times in the past never again. Let’s see what happens. I will use this as much as I can 3-4 times per week. I will update. I used the yellow organic one b for 6 weeks saw nothing. I’m hoping this will show me something

  19. I’ve just heard of Jamaica castor oil…. how can I apply it on my scalp? and after applying,when should I wash it away?

  20. Will the Jamaican castor oil, argan oil and rosemary mix work for black males hair?

  21. So basically Jamaican black castor oil (without mixing any other oil) to apply on your scalp before going to bed can be effective?

  22. Thank you! so basically i need to only put it on my hair and eyelashes before bed and let it sit & shower in the morning. How many times a week should i apply to my hair and eyelashes?

  23. Amanda,

    No, it won’t affect your hair color but yes, it is greasy. It’s thicker and greasier than coconut oil. However, you don’t need to use a lot to get results. With CO, more is less.
    I hope this helps and good luck!

  24. I color my hair..will the oils affect it? And how greasy does it make your hair? I’ve noticed my hair is thinning so im wanting something for the thickness and for my eyelashes to grow. I’ve tried biotin, eyelash serum, vaseline, coconut oil… I stopped using coconut oil just bc how greasy it left everything

  25. I am doing this hair challenge and it said to use the Jamaica Black castor oil 3 times a day on your scalp but wash your hair every 7th day is that a good thing or should I wash it out in hours ?

  26. I used regular castor oil for up to 6 months and saw results. Not the results I expected to see after 6 months but it did thicken it.
    Then I switched to Jamaican castor oil and found that I saw better results within 2 months than I did with the 6 months of regular castor oil. I stopped using oils on my eyebrows for about 4 months but now I’m back at it but this time I used organic argan oil.
    I see results from the argon oil and I have been using it for about a month now. From the argon oil, I have grown more hair around my arch and ends of my eyebrows but I noticed that the hair on my eyebrows is getting thinner.
    I don’t know why but I’m growing hair outside my eyebrows but losing hair inside my eyebrows and maybe it’s because of the argan oil. I am now switching back to Jamaican castor oil as I had the best experience from it. Regular castor oil did take the longest so that will be my 2nd choice after I try Jamaican castor oil.
    I will upload updates on which one I’m doing and how it helped.

  27. Hi Meital I live in Dubai.
    Been reading a lot on both C Oils.. it said the Jamaican oil is the best!! Made my sister send me 5 bottles from the UK. Have seen some results on the front hairline & eyebrows, not much on eyelashes.
    Used 3 bottles on my son’s hair, not very promising results. Also, it’s an easier oil to apply being thinner.
    I used the regular C Oil…before the Jamaican. It’s a heavy/viscousy oil… didn’t get to use it long enough to see results because half way I read about the Jamaican oil being better so switched to Jamaican Oil.

    Now after reading yr readers’ comments & yr replies I’m gonna switch back to the regular c oil for my eyebrows and lids.

    Will it be ok to mix the reg c oil with coconut or olive oil?
    Can I use this mix esp on my lashes??
    Thank you

  28. Sus,

    Jamaican black castor oil is not as pure and can’t be found pure and clean like Castor oil. I wouldn’t risk my eyes getting infected from something that is n’t absolutely pure.

    That’s what I would recommend anyway…

    Hope this helps!

  29. Hi. Great post. I was just wondering, why can’t I use the jamaican castor oil on the eyelids and brows?

  30. I’ve been using Tropic Isle Living Jamaican Black Castor Oil for a while now and I know a lot of women who are using this product to enhance hair health and appearance and to stimulate hair growth.Thank you so much for sharing How to Use Jamaican Black Castor Oil for Hair Growth at the Healthy Happy Green and Natural Party Blog Hop. I’m pinning and sharing.

  31. Wow, I didn’t know the difference between the two castor oils although i’ve been using regular castor oil for detoxification for a while. Thanks for the post

  32. I will say that using this oil really worked for me. I have chronic pain due to spinal disc degeneration which causes lots of stress. Both of my eyebrows became sparse and one nearly disappeared to half its size. I only had to apply the oil a few times before I noticed my brows growing back in. I really hated trying to paint them on as it rarely looked natural and I didn’t want to use standard make up loaded with unhealthy chemicals. I was so pleased.

    I found a small bottle of pure, organic, cold pressed oil on Amazon. I just applied a little with a q-tip and left it on before bed. No mess.
