Tired of expensive eyelash serums? Castor oil, also known as castor oil, promises a natural solution for longer, thicker lashes—and for less than $5.

In a world where eyelashes compete with extensions The Kardashians and the prices of beauty serums are rising faster than the prices of petroleum products, it is TikTok and Pinterest have sparked a mini-revolution: castor oil. That humble, somewhat old-fashioned oil that we once associated with digestive problems or grandmotherly advice is now a beauty star. And for less than 5 euros! Cheaper than a coffee and croissant in a city cafe.

Longer lashes? What is castor oil and why all the drama?

Castor oil, extracted from the seeds of the Ricinus communis plant (don't worry, we won't be cooking anything with it), is rich in ricinoleic acid, vitamin E, and omega-9 fatty acids. These ingredients are said to help strengthen lashes, prevent breakage, and give them that "bossy" look that we usually get with expensive mascaras or serums that cost as much as a weekend at the beach.

Science or just an Instagram myth?

Let's admit it: There is no solid scientific evidence that castor oil promotes eyelash growth. However! Because it acts as a moisturizer and creates a protective layer around the hairs, it prevents breakage and dryness. So: healthier lashes = the appearance of longer lashes. Is it a placebo? Maybe. But if your look gets that dramatic flair, who cares what the lab says.

How to use this pantry wonder?

  1. Buy the right oil: Cold pressed, organic, no additives. Not every mini bottle in the drugstore is a good choice.
  2. Apply like a pro: With a cotton swab or a clean mascara brush. Just above the lashes, not in the eye – unless you want a red look ala Twilight.
  3. Night routine: Apply before bed, leave on overnight, rinse in the morning with a mild cleanser.

What do users say?

On Reddit, TikTok and even the Amazon reviews are full of praise. User @glowupqueen88 says that after a month of use, her lashes were literally “greeting the sun” because they were so long. Another notes that her lashes became so thick that she had to change mascara because her old one simply gave up.

Is this the new holy grail of eyelash care? Yes and no…

Castor Oil: The Natural Secret to Long Eyelashes and Thick Eyebrows

In a world where beauty trends come and go, one ingredient consistently tops the list of natural beauty solutions – castor oil. This miraculous liquid, extracted from the seeds of the Ricinus communis plant, has become an indispensable part of the beauty routine of many individuals looking to enhance their beauty naturally.

Why choose castor oil?

Castor oil is rich in ricinoleic acid, vitamin E, and omega-9 fatty acids. These ingredients help strengthen eyelashes and eyebrows, prevent breakage, and promote a healthy appearance. Regular use can help to grow thicker, longer hair, making it a great alternative to expensive serums or artificial extensions.

How to use it?

For best results, apply a small amount of oil to clean eyelashes and eyebrows before bed. Use a clean mascara brush or cotton swab to avoid contact with eyes. Leave on overnight and rinse with a mild cleanser in the morning.

When should you not use it?

If you have very sensitive skin or are prone to allergic reactions, be careful! Castor oil can cause irritation, redness or even rashes in some people. If the oil accidentally gets into your eyes, it can cause a burning sensation and tearing. So always do a sensitivity test on the inside of your wrist and do not use it if you notice any negative reactions. Pregnant and breastfeeding women should also consult a specialist before use – because we only want long eyelashes, not dramatic side effects.
