If you want naturally long, lush eyelashes without reaching for your mascara each time, there exists a humble ingredient that will grant you this wish. Castor oil, the miracle hair growth ingredient, is found to be especially effective when it comes to achieving unbelievably thick and long lashes (and bolder brows!). It is also known to prevent breakage and stimulate faster and healthier eyelash growth. I decided to incorporate castor oil into my hair care routine about a year ago, and the results have made me stick with it for good. My lashes are now significantly longer, fuller, and oh-so-healthy.

In this article, we have discussed a few insanely simple methods to incorporate castor oil into your beauty regimen to achieve the lashes of your dreams. You won’t have to shell out your savings on exorbitantly priced lash growth serums once you start using these DIY methods.

But first, let’s begin with the fundamentals.

How Does Castor Oil Benefit Hair Growth?

Besides its antifungal and antibacterial properties, castor oil is packed with beneficial nutrients like proteins, minerals, and fatty acids, such as oleic, linoleic, stearic, and palmitic ricinoleic acids. It also contains natural compounds that promote hair growth.

  • Castor Oil Contains Vitamin E

Vitamin E works as a powerful antioxidant that conditions your lashes and keeps them from falling out. It also helps repair damage to hair follicles, which then promotes hair growth.

  • Castor Oil Is Rich In Ricinoleic Acid

Castor oil also contains naturally high levels of ricinoleic acid, an omega-9 essential fatty acid that thickens your lashes and stimulates lash growth.

Castor Oil For Eyelashes – Is It Safe?

As opposed to the wide range of eyelash growth products in the market, which may or may not have side effects, castor oil is a natural ingredient. Much like an all-natural conditioner and at a moderate dosage, it works fine without any side effects.

Even if a little bit gets into your eye, it does not cause any damage. It only blurs your vision if you apply an excess amount (in which case, you can wash it off). The trick to keeping it from getting in your eyes is simple – apply it with precision and in small amounts. If you want to know more about how to use it the correct way, keep scrolling.
