How Does Castor Oil Benefit Hair Growth?

Types of Castor Oil

Castor Oil is being extracted from the natural seeds of castor beans.
Pure organic Castor Oil will be clear with no odor, while blended oils may have an unpleasant smell, and some might not produce desired results.

Always before you purchase, read the label carefully and be sure it is 100% pure organic castor oil. Castor oil blended with other oils or ingredients may irritate the skin or may not deliver the desired result.

There are two types of Castile Oil: Cold Pressed Castile or “clear” (which is just light yellow) and Jamaican Black Caster (“dark brown”). Both work similarly.

The clear and dark versions of castor oil are both said to be used for beauty treatments. The Jamaican black type has developed a reputation as being the preferred choice in many cases. However, both types of castor oil have the same properties that may promote eyelash growth.

How to use castor oil on your eyelashes

Before you apply castor oil to your lashes, do a simple safety test.
First, apply castor oil on some other part of your body, like your arm, for 24 hours and see if you experience any irritation or discomfort, particularly if you have allergies or sensitivities to traditional treatments.

If no skin irritation occurs, the oil should be safe to use on your eyelashes. The ideal time to treat your eyelashes is just before bedtime. Gently run the cotton swab along the top of your lash line.

Just make sure not to put too much castor oil directly into your eyes since this could cause a burning sensation in those areas. Your vision could be highly irritating. If such a thing happens, you should wash your eyes immediately with water.

Revamin Lash effectively nourishes lashes and eyelid skin, creating optimum conditions for eyelash growth.

Is there any research to support using castor oil for eyelash growth?

Ricinoleic acid, which makes up almost 90% of castor oil, might help to reverse hair loss. Studies have shown that ricinoleic acid has antifungal properties, plus it can stimulate growth in skin cells where new hairs are formed.

More such research needs to be done to understand if ricinoleic acid can also treat other types of hair loss besides eyelash growth.

How Long Does It Take For Eyelashes To Grow Back With Castor Oil?

Castor oil is a natural remedy to grow your eyelashes. It only takes about 3-6 months to work, but it has been shown to boost the thickness and length of lashes over time successfully!

The power of castor oil can be seen immediately when you use it regularly for just one month. Lashes will become thicker, fuller, more defined within ten days. In 30 days, they’ll visibly grow without any mascara whatsoever.

After 60 nights (about 2 1/2 months), your natural lash line should look dramatically different from what you’re used to seeing at daybreak each morning —they’ll resemble false lashes.


Castor oil is one of the most affordable, natural, and safe ways to grow your eyelashes. With a bit of patience and consistency, you can enjoy longer, more beautiful lashes in no time at all!
