Does caster Oil Grow Lashes


Vegetable oil, known as castor oil is derived from the bean of the castor tree. The fatty acids in castor oil are regarded to be very good for the skin. Many people claim that regularly using castor oil has helped them develop longer, thicker eyelashes and brows. Is it really efficient?

What is castor oil?

Vegetable oil, called castor oil, is produced from the seeds of the castor oil plant. Based on the method of extraction, castor oil is divided into a number of kinds. One 2003 study found that castor oil enhanced hair’s “luster,” which would imply that eyelashes would benefit from the same treatment. The sections below address different types of castor oil and whether or not they work to make eyelashes look better. We also go through its application and the associated dangers.


Jamaican black castor oil is darker because the makers roast the castor seeds before extracting the oil. On the other hand, cold-pressed castor oil is light yellow in color and smells moderate. Both forms of castor oil have been used anecdotally on the eyelashes, despite the fact that neither form has been the subject of scientific research to determine which is best for eyelash maintenance.

There is also hydrogenated castor oil, which is produced by treating castor oil with hydrogen to render it solid at normal temperatures. Many cosmetics contain hydrogenated castor oil. It is advisable to use high-grade, pure castor oil on the body. These varieties may be safer and more effective.

Castor oil has similar qualities that may help improve the appearance of eyelashes. According to a study published in the International Journal of Science and Research, castor oil contains 90% ricinoleic acid. Ricinoleic acid includes a lot of triglycerides, which may help keep your eyelashes moisturized. Furthermore, the oil contains omega-6 fatty acids, which may help promote hair health.

According to 2015 research, ribinosine may be a prostaglandin D2 inhibitor, which suggests it may be useful in preventing hair loss.  According to other studies, balding scalps produce more prostaglandin D2 than people with thicker hair. Prostaglandin D2 rates were higher in the bald than in the hairy scalps of 17 males with male pattern baldness.

According to the study published in the International Journal of Science and Research, using castor oil on the eyelashes can enhance blood circulation to the hair root and induce new development.

How effective is castor oil for hair growth

  • Castor oil contains vital elements such as proteins, minerals, and fatty acids such as oleic, linoleic, stearic, and palmitic ricinoleic acids, in addition to its antifungal and antibacterial characteristics. It also has natural ingredients that encourage hair development.
  • Vitamin E is found in castor oil: Vitamin E is an antioxidant that nourishes your lashes and prevents them from falling out. It also aids in the repair of hair follicle damage, which encourages hair growth.
  • Ricinoleic acid is abundant in castor oil: Castor oil is also naturally high in ricinoleic acid, an omega-9 important fatty acid that thickens and accelerates lash growth.

How can I be sure castor oil is safe?

Castor oil is a natural substance, as opposed to the numerous eyelash growth products on the market, which may or may not have adverse effects. It works similarly to an all-natural conditioner, and at a moderate dosage, it has no adverse effects.

Even if a small amount gets into your eye, it does not cause any harm. It only blurs your vision if you use too much of it (in which case, you can wash it off). The key to preventing it from getting into your eyes is to apply it precisely and in small amounts. Continue reading if you want to learn more about how to utilize it correctly.


Castor oil is an ingredient in numerous cosmetic products, such as lipstick and skincare items. Scientists claim that castor oil has a low toxicity level and that 100% hydrogenated castor oil is suitable for use in cosmetics. But in other people, it might result in an allergic reaction, including skin irritation.

People should test castor oil on an area of skin far from their eyes and face before using it on their eyelashes. Castor oil users should wash it off and cease using it if it irritates them.

Does castor oil work?

Zeichner explains that “Castor oil is commonly used as a natural treatment for eyelash and brow development.” However, the majority of the evidence for castor oil’s ability to promote hair growth is merely observational.

Recent research suggests that some castor oil constituents may prevent hair loss rather than promote hair growth. Controlling lash loss, though, can make your lashes overall thicker because you won’t be losing as many hair follicles daily.

Specifically, castor oil has been shown to support the health of your lashes in three ways:

  • PGD2 diminution Castor oil’s main component, ricinoleic acid, may stop lash thinning by reducing prostaglandin D2 (PGD2), a lipid type connected to hair loss. A 2015 study found that castor oil significantly decreased PGD2 levels in computer models, although it is uncertain how castor oil affects people.
  • management of inflammation. If you apply cosmetics to your eyes or eyelashes, castor oil might be especially helpful because of the anti-inflammatory properties of ricinoleic acid. Cosmetics like mascara can cause inflammation along the lash line, which makes it easier for your lashes to fall out.
  • Keep the moisture in the lashes. Castor oil may be able to enhance the health of your current lashes by acting as a conditioner. Castor oil can be helpful because of its moisturizing effects.

How to Use castor oil

One of the best brands that makes eyelash products is Grande Cosmetics with their GrandeLASH serum. So now you are aware that castor oil won’t necessarily cause your eyelashes to grow like wildflowers. But why not give it a go if making them look glossier and plumper sounds appealing?

This is how

  • Hold off till bedtime. Yes, it is tedious to wait. But if you want lashes that look thicker, it’s worth the wait! Your lashes can absorb castor oil for several hours if you apply it before going to bed. Castor oil is sticky, so using it while you’re out and about could cause it to attract grit and dust.
  • Remove any eye makeup. You don’t wear mascara to sleep, do you? To get ready for your lashes, clean the skin around your eyes.
  • Rub some oil on a cotton swab. You’ll have a rough night if you get some more oil and castor oil in your eyes.
  • Apply the swab to your lash line. Again, be patient with this because your eyes are delicate. Trace the swab lightly along your lash line. If you get oil in your eyes, wash them out right away.
  • Wipe it away. Cleanse your lashes in the morning with water and a light soap or makeup remover. You’re done until the evening!

Last word

More research is required. Castor oil might improve eyelash health and lessen lash loss. Castor oil should always be used lightly and refined if you want to experiment with it. Castor oil can cause negative side effects, so stop using it pretty quickly and see a doctor.
