If you’ve ever been curious about natural remedies for lash growth, you probably came across castor oil as a popular option. Many people swear by using it not only for their hair but also for their eyebrows and lashes.

But does castor oil make lashes grow? Read on to get the explanation of what actually happens – plus some quality products and tips on how to use it safely and effectively!

What Is Castor Oil?

To understand what benefits castor oil for eyelashes might have, it’s important to understand how it interacts with the skin and hair.

Castor oil is a vegetable oil that comes from the castor bean plant. It has been used for centuries for its medicinal properties, but today it’s particularly known as a natural remedy for boosting hair and lash growth.

One of the key components of castor oil is ricinoleic acid, which is believed to have anti-inflammatory and antibacterial properties. But more importantly, this oil has both emollient and humectant properties.

This means that the oil’s fatty acids (natural humectants) moisturize and soften the hair by preventing water loss. This effect is what helps relieve dryness and support hair structure.

Castor oil also naturally increases blood flow and circulation which is thought to potentially support lash follicles and encourage the growth of healthier and stronger lashes. You can learn more about that here.

So How Does Castor Oil Grow Lashes?

Here’s an honest answer to this question: There is no scientific proof that castor oil can actually make your eyelashes grow, in terms of triggering actual new hair growth.

But due to some of its useful properties that we mentioned above, it can make your lashes feel stronger, which as a result makes them look thicker as well.

It hydrates your lashes, decreasing the risk of breakage, which (along with its antimicrobial and anti-inflammatory properties) greatly improves the health of your current lashes.

How to Use Castor Oil for Eyelashes Effectively

To get the most benefits out of castor oil for lashes, it’s important to use it properly and safely.

Castor oil should be applied nightly for best results. To avoid contamination, always use a clean applicator brush to apply castor oil to your lashes. Don’t use your fingers, as they might carry bacteria or other contaminants, plus it makes the application harder and less safe.

You can apply it to your upper and lower lash line, coating each lash thoroughly while doing your best to avoid entry into the eye area at the waterline.

Leave it on overnight. This will give the oil enough time to penetrate the hair follicles and then wash it off in the morning.

Most importantly, be patient. Lash growth is a gradual process that takes time, so it may take several weeks to see results.

Also, it’s highly advised to get a product that is 100% pure, cold-pressed, and free from additives or preservatives, so here are some recommendations:

Live Fraiche Organic Castor Oil Lash Boost Serum

The small packaging of this product makes it perfect for testing out castor oil for lashes for the first time, and with its double-sided brush you can easily and precisely apply it on both the lash roots and length.

Cliganic 100% Pure Castor Oil Lash Kit

If on the other hand you want to really commit to this experiment and get yourself a bigger bottle, then definitely go for this kit from Cliganic that’s only $12!

This kit contains everything you need for your lash growth routine as it provides an 8 oz bottle of 100% organic castor oil and two small refill bottles with a mascara and liner brush as well as a funnel.

Are There Any Side Effects of Castor Oil on Eyelashes?

While castor oil is generally considered safe on the skin, there are some potential side effects of castor oil on eyelashes to keep in mind.

Some people may experience irritation, redness, or itching after using castor oil, so if you experience any of these symptoms, discontinue use immediately and consult a healthcare professional if it doesn’t go away.

It’s also worth noting that castor oil is a thick, viscous oil that can be difficult to remove and also might be uncomfortable for some.

So be careful when applying it to make sure it doesn’t get in your eye, and use a gentle, oil-based cleanser to remove it from your lashes.

Other Options for Lash Growth

While castor oil is a popular choice for lash growth, there are other products and remedies that can also be effective and are worth exploring.

Rosemary oil is another popular option (read about that here). Oils like coconut or argan oil are also rich in nutrients that make them a good option for moisturizing, strengthening, and promoting the growth of your lashes.

You can find a comprehensive list of different oils that effectively enhance eyelash growth – plus their top-rated products here.

However, if you’ve already experimented with natural oils and are searching for a more significant change in your lash length, look into lash growth serums.

For a convenient two-in-one approach, there are even mascaras that help stimulate lash growth.

So Is Castor Oil the Secret to Long, Luscious Lashes?

While many people reported good results from this oil, some do find it to be either irritating or uncomfortable, which means it’s not the ultimate solution for everyone.

That being said, castor oil is a safe and natural option for promoting lash health, just be sure to choose a high-quality product, use it in moderation, and be patient. With time and consistency, you may see the results you’re looking for!

Also, if you are interested in growing your brows as well, castor oil might help with that too.
