Does Castor Oil Help Your Hair Grow?

Does castor oil help your hair grow? Find out and learn how it can be an effective remedy for your hair, eyelashes, and eyebrows!

So does castor oil help your hair grow? Well, using castor oil for your hair is the ideal way to take care of your hair, eyelashes, & eyebrows! As surprising as it may seem, castor oil has properties that rapidly accelerate hair growth (naturally!)

The majority of users who apply castor oil to their hair see the results of using castor oil within the first couple of weeks.  Users will see that their hair significantly grows faster, longer, and thicker.

Moreover, not only does hair growth practically double in length after multiple applications, castor oil deeply nourishes both the hair and hair follicles, right down to the scalp! The hashtag #longhairdontcare just got a whole new meaning.

How does castor oil act on your hair, lashes, & brows?

Pinpointing out what exactly in castor oil creates such a positive effect on our hair {lashes, scalp, brows} is tricky. Whatever it may be, those who have tried castor oil for this purpose tell about observing a significant difference in the health of their hair within just 2-3 weeks of applying castor oil.

Though it’s not guaranteed, Marianne and my studies of castor oil show a consistent trend of how the vitamin E prevalent in castor oil is what contributes to such positive effects of castor oil on our hair. It makes sense because vitamin E favors the cutaneous microcirculation (blood circulation of the smallest blood vessels affecting the skin). Castor oil thus brings extra nutrients and nourishment to skin {scalp, hair follicles, nails, etc..}

castor oil for your hair

Therefore, in a localized area such as the hair bulb, castor oil directly helps to strengthen the hair from the root which enables faster hair growth and even influences the decrease in hair loss. And if you massage castor oil into your hair it can bring your hair an even deeper level of nourishment and replenishment.

More generally speaking, castor oil will deeply nourish your scalp.  In doing so, you will see that your scalp + hair will have a much healthier touch and texture.  If you are prone to dandruff, castor oil can provide the relief you are looking for. If your hair is dull or otherwise “lifeless” (we all have those days.) then castor oil would be the perfect solution to bringing your hair back to life.

Fun tip: Take photos of your hair before/after using castor oil for a couple of weeks and see the difference it made for you. If you do this, please do let me know the difference you see and feel with your hair! 🙂

Castor oil is routinely used in Africa and the Caribbean to smooth soften thick and frizzy hair.  In these regions, castor oil’s cousin, black Jamaican castor oil, is a favorite because it particularly acts on thick/frizzy hair. Learn more about black Jamaican castor oil here.

Castor Oil on Eyelashes & Brows

Before continuing, let’s not forget that castor oil is also used for your eyelashes & eyebrows.  Applying castor oil on these areas is safe and efficient.  Your eyelashes will thank you for it!

Before my castor oil days, I used to get many sites on my eyelids. Once, one got so infected that I had to go get it surgically removed. For months after I had a red scar. And my lashes became thin, curled, and were always falling out.

Now I use castor oil regularly, and no one can even tell I used to have problems.  I even wear less mascara (or not at all) now because my lashes are longer and thicker and it’s all thanks to castor oil.  I’m confident castor oil can positively help you, too!

Have a look at the best ways to put castor oil in your hair.

How to apply castor oil to your hair?

To simplify the application of castor oil (because applied alone it’s like thick honey), I would recommend to first dilute it with another oil.  In this case, my preference goes to either aloe vera or coconut oil.

Both are more fluid/liquid so they make the perfect combination with castor oil which is viscid. They also have complimentary effects and benefits (cell regeneration, synthesis of collagen and elastin) making these two substances the ideal allies to reinforce and strengthen your hair, lashes, and browse.

To create the right texture for my hair (which was long and brittle but now is short and thicker) I mix half and a half (half castor oil, half other).

You can either apply it directly on your scalp or on the body of your hair.  Personally, I start with my scalp and massage (working down). I then put it all up in a bun and cover with a hot towel.

Of course, you can adapt your application method depending on your personal preference.  I do recommend putting a hot/humid towel over your hair. I normally do (you can also heat the oil mix in the microwave).  Once warmed/heated, castor oil has even more nourishing properties. The oil works deeper to rejuvenate and replenish damaged hair, right down to the follicle!

How often should you use castor oil on your hair?

2 hours with the oil mixture on suffices greatly, however, don’t hesitate to let it soak in overnight.  In any case, just make sure to adequately shampoo or wash your hair and rinse thoroughly. With its viscous texture, castor oil can be difficult to remove.  It is totally normal to have to shampoo 2-3 times before all the oil residue is off.

The frequency of applying castor oil to your hair will depend on you. But nevertheless, I would suggest starting with a minimum of 3 times per week, especially if you are looking for faster results within the first few weeks of utilization.

In addition, I would not recommend using castor oil for more than it’s purpose.  Castor oil is meant to replenish/nourish/boost your hair naturally.

So there isn’t any need to insist by overusing it. Once you are satisfied with the results, decrease the frequency in which you apply castor oil to your hair. You can always adjust as need be.

Before you go must-knows

Before you head out, know that even before using castor oil, taking great care of your hair can be achieved simply by brushing. Crazy, right!? Brushing is often overlooked as a way to care for one’s hair, but don’t be the one to make that mistake!

Castor oil is definitely not gender-specific

Is your man/brother/partner a hipster? If he is strutting his stuff with that scruff, then engage him in conversation about the wonderful powers of castor oil. Men need to take care of their beard too, ladies, so share the love for castor oil.

Beards, mustaches, goatees, etc., also require daily maintenance and need rejuvenating and replenishing.  If you’re a lucky woman or man of a man with a beard, then you know just how important it is to make sure that beard is soft, supple, and lookin’ good.

So that’s all for our guide on: “does castor oil help your hair grow?” I hope our guide helps you in growing and nurturing your hair in the right way!

  1. Hi Brittany!
    Is there a “pre-mixed” castrol/coconut oil hair product. I am new to this and would like to obtain a premade product to get me started…then I can experiment with mixing my own lol…my hair is fine, thin and falling out. Thank you for your guidance!

    • Hey Kelley! Thanks for writing me 🙂 An interesting thought, indeed! But I don’t think of any quality brands that do that, though I can check again. The easiest would be to put some coconut oil in your palm, and dribble a few drops of castor oil on it, rub it between your hands to melt/mix and apply directly on your hair. No need to add any other fancy stuff – just castor oil and coconut oil together will be fine! Don’t worry about getting the amounts perfect, just experiment a little. I usually do this and now I know just about the amount I need to cover my hair. Best of luck girl!
