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.

    My wife introduced me to castor oil over forty years ago. Have used it ever since for cuts. I put the castor oil on the cut after washing it and cover with a bandaid overnight. I have also used castor as a linament using a flannel wrap and sometimes a heating pad for sore areas of the body. It works really well. She got her information about castor oil and its uses from the Edgar Cayce Readings.

    Castor oil is amazing for hair! I always add some rosemary EO to mine.

    It might be a new formula for westerners,
    But in South India we use it regularly,
    * orally with coffee to cleanse the digestive system ( 2 tablespoons in a cup)
    * Removing tan
    * Any marks on the skin
    * As a Lubricant.
    * Massage oil
    * offcourse for all hair related problems
    Like: Greying,hairfall etc
    And healthy practice considered here is,
    The duration of drenching it on your hair for more than 1 hr leads to frequent cold and running nose as it is a very good coolant,
    And apart from eyes you can also apply it on umbilical hole overnight,
    To remove it quickly and efficiently we use shikakai (Google),
    We don’t add anything to it.

    Coconut oil must be warmed before using. Actually Ayurvedic texts don’t prescribe coconut oil on its own without herbs infused in it. The molecular size of the oil is such that it doesn’t penetrate scalp very well. But sadly in India it’s highlt popular to use brands which aren’t event 100 percent coconut and certainly not virgin!

    I was wondering if oils like these are OK to use if your hair is professionally colored ?

    Thanks a lot for this great article. I’m a fan 🙂 So nice to read comments from other users too. My brothers hair used to be thick and curly but not he’s loosing it. He talks about Minoxid tablets but I’m not a fan of synthetic medicin. I read on an information site that castor oil is good for this condition and I can read user comments that some are using it for the same purpose. Do anyone have experiences about castor oil and the effect on hair growth/hair thinning? I used castor oil on my skin years ago and I know it’s a nice oil but I would appreciate any experience on hair. Thanks

    Great article! I have been using it for a month now and I started noticing difference. Just a tip that I do: instead of applying the oil on my hair/scalp with hands, I put the oil in an empty glue bottle( you can buy theses bottles from any crafts store) and I apply the oil on the scalp directly so my hair doesn’t get messy or my pillow

    Is there any harm in not washing the Castor Oil off your head?

    My daughter has 6 years and suffers from hair loss. Can you help me?

    I developed a formula that uses the ingredients Katie suggests in her recipe along with others that are beneficial for hair growth and scalp health. The ingredients are:

    Castor oil
    Coconut oil
    Olive oil
    Grape Seed oil
    Shea Butter oil
    Jojoba oil
    Argan oil
    Emu oil
    Essential oils: Cedarwood, Rosemary, Lavender, orange peel, lemon peel, chamomile.

    Question: I made this but it seems so thick and hard to apply directly on the scalp. I got the Jamaican castor oil and the Argan oil you linked. Would heating the mixture help?

  14. Gloria Avatar

    Thanks for your tips… I mix equal amount of castor oil, olive, almond and coconut. Next after wash, hair feels Devine…

    P/s: Just want to comment that I also love your website and have learned so many new and natural ways to live! It is always “back to basics” for me too! 😀

    I just read a “recipe” for a hair growth serum that contains castor oil, honey and egg yolk. Any thoughts on this?

    Hi Katie,
    Since having my babies my hair has continuously fallen out. I’m about 6 months post nursing after 2 and 1/2 years. I was nursing when I got pregnant with my youngest. I’m actually wondering at this point if I have a something going on with hormones, tyroid, Adrenal fatigue (or all).
    I definitely notice I have more hair falling out when I am stressed.
    Did you do the test for thyroid at your OB or regular doctor?
    Do you have an suggestions for someone who is newly diagnosed (assuming that’s what’s going on).

    Can you put castor oil in your shampoo and just mix it up and use it everyday
