Castor Oil for Thicker and Longer Hair

I’ve been experimenting a lot with castor oil lately as a natural beauty remedy. I already use it in my oil cleansing blend each day, and I’m enjoying the results from using castor oil packs on my skin.

Years ago, a friend mentioned that she loved castor oil for hair and eyelashes. I was really skeptical because castor oil has a very thick and sticky consistency that I couldn’t imagine using in hair. I did some research and found out that I had been seriously missing out on a simple and really effective traditional beauty remedy…

Benefits of Castor Oil for Hair and Skin

Castor oil is an age-old beauty treatment that has been largely replaced over time by fancier beauty products with more ingredients and a bigger price tag.

Castor oil has natural antibacterial and antifungal properties and is high in vitamin E, minerals, proteins, and omega-6 and -9 beneficial fatty acids. Its unusually high ricinoleic acid ratio makes it beneficial to skin and hair.

In fact, castor oil has traditionally been used topically for acne and other skin conditions, as well as hair loss, rashes, and more. If you want to try it for skincare, I recommend this handcrafted castor oil cleansing blend.

What Does Castor Oil Do for the Hair?

Castor oil can be used on the scalp to help prevent and remedy hair loss and it is effective at this for several reasons. Its antibacterial and antifungal properties make it beneficial against follliculitus, dandruff, and scalp infections and its ricinoleic acid content helps increase circulation to the scalp and improve hair growth.

Ricinoleic acid is also said to help balance scalp pH which can also help replenish the scalp’s natural oils and undo some of the damage of harsh chemical hair products (and even damage from no-poo, due to over alkalinity). The antioxidants in castor oil also support the keratin in hair and help make hair stronger, smoother, and less frizzy.

“Three Times the Growth!”

How to do a castor oil treatment for natural hair and eyelash growth- simple natural remedyThere are hundreds of testimonials from people who used castor oil to increase their hair growth 3-5 times the normal rate. A friend of mine was struggling with postpartum hair loss and even once her hair loss slowed, regrowing her hair was difficult.

She measured her hair growth for a month and it grew almost half an inch. The next month, after using castor oil hair treatments twice a week, her hair had grown almost 2 inches. She tested this again the following month and noticed the same result and that her hair was dramatically thicker.

What Type of Castor Oil for Hair?

There are several options for castor oil hair treatments. I prefer to make my own, but there are some pre-made options (this is a good one that I’ve tried in the past).

To make my own, I mix castor oil with another hair-healthy oil (options listed below) and herbs to help support scalp health. Unrefined and cold-pressed hexane-free castor oil is preferred.

Castor oil is extremely thick and viscous so I prefer to mix with jojoba or argan oil in a glass dropper bottle for easy application.

Jamaican Black Castor Oil

There is a special type of castor oil called Jamaican black castor oil that has extremely good reviews. I tried it as well and it seemed to work about the same as regular castor oil on my hair, but it seems that it might provide additional benefit for those with thick or dry hair (my hair is fine/oily).

How to Use Castor Oil Treatments on Hair

Castor oil can be very beneficial for hair growth if used correctly. Small amounts of plain oil can be used for an all-over treatment. Like many things in life, more is not always better, and only a few drops are needed per treatment. The additional oils are completely optional.

How Often

I personally use this castor oil 1-2 times per week. It can be used more often, though I didn’t see any increased results with using it daily.

When to Use

I’ve found that this treatment works better on damp but not wet hair. I keep a spray bottle of water in the bathroom and just spritz my roots before applying.

For maximum benefit, I leave the treatment on for several hours or overnight. After applying, I use a shower cap or towel to avoid getting the oil on furniture or a pillow.

How to Remove the Oil

Removing the castor oil can be difficult, especially with natural shampoos. I’ve found that using a small amount and leaving it on overnight will result in most of the oil absorbing into the hair and scalp and make cleanup easier. In fact, I’ve been able to use dry shampoo and not wash on a few occasions. When I do shampoo, I use a natural shampoo or mud shampoo as normal.

An alternate way is to crack an egg and whisk until smooth and then massage the egg into the scalp. This helps break down the oil and adds additional nutrients to the hair. It is messy though, so I’d recommend doing this in the shower.

Another less-messy way is to condition your hair before getting in the shower, massaging conditioner into the scalp to help remove the castor oil. Then, shampoo as usual.

Important Notes:

With any new oil, herb, or product, test a tiny amount on your inner arm to make sure you don’t have a reaction. While reactions are rare, some people will notice irritation from castor oil.

I’ve also used this in combination with my hair growth serum with great results. (I use the serum first to dampen hair, then apply the castor oil.)

It is also important to support the body nutritionally and hormonally with hair loss, as this can often be a sign of an internal problem.

BONUS TIP: I rub a tiny amount of castor oil on my eyelids at night to help eyelash growth as well. It is also part of my eyelash growth serum recipe.

Castor Oil Hair Serum Recipe

A mix of castor oil and jojoba will make a hair serum to help your hair grow faster, stronger, and smoother.
Prep Time1 minute
Author: Katie Wells



  • Combine the ingredients in a dark-colored dropper bottle.
  • Shake to mix.
  • Use the dropper to apply to the scalp. I part my hair right above the ear on one side, add a few drops of castor oil, part again about ½ inch from that part, add more castor oil, and so on until I’ve coated my whole scalp.
  • Then, I massage for 5 minutes to make sure entire scalp is coated and to help increase circulation.


This will make enough for 5+ uses depending on the length of your hair.
If you’re not a fan of using castor oil, some people have found coconut oil for hair to be a better fit.
For best hair health, I recommed using the above with Wellnesse Shampoo and Conditioner (from yours truly!), which I formulated to meet all of my criteria for safe, non-toxic, and naturally nourishing hair care.

My Own Results with Castor Oil…

Last year, when I was under extreme stress for a short period of time (finishing my book *ahem*), I noticed increased hair loss. My Hashimoto’s makes me more susceptible to hair loss when I’m under stress, and I was stressed about my hair loss (vicious cycle).

To combat this, I experimented with natural castor oil treatments both alone and mixed with other oils. I too noticed that my hair seemed stronger and that there was definitely less hair in my brush each day after a few weeks of castor oil treatments. Additionally, I started seeing tiny new hairs all around my hair line.

Random observation:

I split my head open when I was younger, requiring 8 staples in my scalp. Where the scar is, I have a patch of super-curly hair that falls in a perfect ringlet, even though the rest of my hair is wavy/straight. The castor oil seemed to help make this hair patch smoother, though it grew at a faster rate than the rest of my hair.

Now, I’ve made these castor oil hair treatments a regular part of my weekly routine and often do them at night, while wearing my blue blocker glasses and reading or watching a movie with my hubby.

    I was skeptical, but I’ve been putting pure castor oil on a cotton swab and applying it to my lashes for three weeks now. My lashes are definitely fuller and longer. I’m going to try your recipe on my scalp now.

    THanks for all you’re wonderful and informative articles! I love your website. Wondering if I can use the same castor oil you recommend for hair loss for my castor oil pack as well? Thanks!

    I was wondering if there is a difference between ‘cold pressed’ and ‘cathartic’ castor oil?

    I’m worried that castor oil will clog my pipes! Has this been a problem for you? Do you have any special tips other than rinsing the pipes with hot water?

    Hello Wellness Mama! First, I ?? Castor oil for my skin. I work in furniture design and for all the saw dust/concrete dust my skin’s exposed to Castor oil has been my saving grace! Not just for keeping it moisturized but as an insect repellent as well.
    Never having tried it in my hair, I’m curious if it’d share the same benefits as the treatments if I put a few-several drops in my shampoo & or conditioner. I’m one who says they’ll do treatments and always seem to let em slip through the cracks. Curious if there’s any pros/cons to this approach. Any advise would be much appreciated!

    Would like to know if there is anything for sore feet, like for soaking? Bottom feet hurt, have corn on bottom of foot. And not sure what it is (likely a corn of some kind) on side right of foot behind my little toe which hurts. [I have heard some say to put duct tape on for few days, when take off suppose to take corn.] Any suggestions???

    You may try foods or supplements that is rich probiotic because it improves overall health and wellness of hair, scalp and follicle function and by using hair care products with probiotics, you can regulate the microflora of your scalp. A balanced bacteria microbiome means a healthy scalp and an optimal environment for flourishing hair growth.

    I was just wondering if anyone has any experience using it on your ends after showering? Like a post-shower final balm?

    you mention castor oil for eyelashes, please let me know how you do it… thankyou!
    I put a few drops on my fingers and rub on my eyelashes top & bottom, but perhaps you have a more efficient way.

    Could I use this on my eyelashes as well rather than making two separate serums?

    For external remedies castor oil is fantastic. I have also used a couple of high quality supplements with great success that is very noticeable (and these three supplements are cheaper than the shampoos and expensive hair loss products they sell out there). I have used Garden of Life Vitamin Code Raw Zinc, Pharma Nord SelenoPrecise and Lugols iodine for increased hair growth and thicker hair. It works because it addresses hormonal and thyroid issues naturally.

    How do you use the Castor oil to help with the growth of your eye lashes.Please let me know.

    If you mix the castor oil with coconut oil, it washes out very well. Coconut oil is also beneficial for hair and skin. You can still mix the other oils in (along with beneficial essential oils) if you prefer.

    Can black Jamaican castor oil be used in your shampoo bar recipe instead of the light colored one? Thanks.

    I’m encouraged by the results you’ve experienced… this is as a woman. I am looking to help my son with hair loss/thinning he’s experiencing. With the obvious differences in hormones, would these combinations of oils and herbs be effective for men? If not, can you suggest a source for natural treatments/diets to help men with hair loss situations. Thank you in advance…

    I use a lot less castor oil and just leave it in. I don’t use shampoo or conditioner except for straight coconut oil as a conditioner, and it seems a waste to put the oil into my hair and follow with a harsh washing. I have coarse wavy hair and rub a tiny bit of castor oil into my fingers, then only apply where needed — where the ends are dry, or where the hair growth is sparse.
