Is Castor Oil Good for Your Eyelashes?


Castor oil, a vegetable oil derived from the bean of the castor tree, is known for its various health benefits. It’s been used worldwide for many purposes, including treating acne and inflammation, reducing wrinkles and age spots. But one question that often comes up is: “Is castor oil good for your eyelashes?” Let’s delve into this topic.

Nutritional Composition of Castor Oil

Castor oil contains different kinds of nutrients and compounds that benefit our bodies. It’s rich in fatty acids, which can improve the shine of eyelash hairs and give them the appearance of being thicker. Castor oil also contains 90% ricinoleic acid, which has high levels of triglycerides that may help moisturize eyelashes. Additionally, the oil contains omega-6 fatty acids, which may help improve the health of hair.

Benefits of Castor Oil for Eyelashes

Eyelash Growth

While there’s no scientific evidence that castor oil helps eyelash hair grow, many people report that with regular application, castor oil has helped them grow thicker, longer eyelashes and eyebrows. A study found that ricinoleic acid, a chemical compound that makes up almost 90 percent of castor oil, might help reverse hair loss.

Appearance of Eyelashes

Castor oil may help make the eyelashes appear thicker or glossier. One study from 2003 showed that castor oil increased the “luster” of hair, which might suggest that the same is true for eyelashes.

How to Use Castor Oil for Eyelashes

Before you start using castor oil on your eyelashes, it’s important to do a patch test by applying a small amount to a small area of skin, such as the arm, to test for any allergic reaction. If you don’t develop any skin irritation, the oil should be safe for use on your eyelashes.

Here’s a step-by-step guide on how to use castor oil on your eyelashes:

  1. Make sure your eyelashes are clean and completely free of makeup.
  2. Pick up a small amount of castor oil by dipping a cotton swab gently into the oil.
  3. Delicately run the cotton swab along the top of your lash line, taking great care not to allow any of the oil into your eye.
  4. Wash off the castor oil in the morning with water or makeup remover.


Q: Can castor oil irritate my eyes? A: Yes, care must be taken not to let the oil come into contact with the eyes, as it can be highly irritating.

Q: How long does it take to see results from using castor oil on eyelashes? A: With regular use, lashes should have less breakage and have more luster in two to three weeks.

Q: Can I use any type of castor oil for my eyelashes? A: It’s recommended to use pure castor oil. Castor oil that has been blended with other oils or ingredients may cause irritation, or not produce the result you’re seeking.


While there’s no scientific evidence that castor oil can make your eyelashes grow, it can make them appear glossier and thicker. It’s always important to do a patch test before using it on your eyelashes to avoid any potential allergic reactions. Remember, every individual is unique, and results may vary.
