Let’s admit it. Long, thick eyelashes are one of those things we all secretly wish we had naturally. They make your eyes pop even without makeup. But not all of us are born with lashes that could compete with a mascara ad, right?
So, the question on everyone's mind is this, does castor oil actually help your lashes grow? Or is it just another one of those age-old beauty hacks that sound good on Instagram but don’t really work?
If you’ve been tempted to try castor oil for eyelash growth, this one’s for you. From science-backed facts to real application tips, and even a breakdown of the safest way to apply it, we’re going all in..
What’s So Special About Castor Oil?
Let’s start with the basics. Castor oil, also known as arandi ka tel in India, is not new. It’s been around in Ayurveda and desi skincare routines for centuries.
But here’s what makes it worth paying attention to now, especially for lashes:
- Rich in ricinoleic acid, a powerful fatty acid that promotes hair health
- High in Vitamin E, which helps reduce hair breakage and supports regrowth
- Naturally anti-inflammatory, making it safe for use even around your eyes
- Deeply hydrating, so it prevents your lashes from becoming brittle and falling out
Basically, this oil creates the ideal condition for your lashes to grow longer and stay stronger.

What's Science Saying?
Here’s where it gets interesting.
While no oil can create new hair follicles, what castor oil can do is nourish your existing ones. According to research and thousands of beauty reviews globally, the fatty acids in castor oil improve blood flow around hair roots. That’s what helps lashes grow thicker and fall out less.
In fact, when paired with rosemary oil, it’s clinically shown to promote up to 42,000 new strands in 90 days. That’s huge, especially if you’re struggling with thinning lashes.

Why Are Indian Women Obsessed with Castor Oil for Lashes?
Scroll through Indian beauty pages or ask your mom’s generation, and you’ll hear the same thing, castor oil works.
Here’s why women are switching to it over lash serums:
- It’s natural and chemical-free
- Works beautifully even for sensitive eyes
- Easy to apply and cost-effective
- Shows results in 2 to 4 weeks with regular use
And most importantly, it doesn’t require a prescription or come with scary side effects.
Top Benefits of Castor Oil for Eyelashes
Let’s break it down. What will you actually get from using castor oil on your lashes?
1. Fuller-looking lashes
Your lashes will look denser because the oil helps reduce fall and breakage. The result? A visibly thicker lash line.
2. Better lash strength
It strengthens each lash from the root to the tip, so you’re not losing hair every time you wipe off your kajal.
3. Hydration for dry, brittle lashes
If your lashes feel stiff or fragile, castor oil will bring back the softness and flexibility they need to grow properly.
4. Safe nourishment around the eye
Since it’s natural and chemical-free, it’s perfect even if you have sensitive skin around your eyes.
Things to Know Before You Apply Castor Oil on Lashes
Now before you dive in, let’s talk about a few must-knows. Because this isn’t like slapping oil on your scalp and calling it a day.
1. Always go for cold-pressed castor oil
Cheap oils often have additives or are heat-processed, which kills off all the nutrients. Choose a pure, cold-pressed version like Soulflower Castor Oil that’s made without any artificial ingredients.
2. Use a clean applicator
Never dip your fingers into the oil bottle. Use a clean eyeliner brush or a mascara wand to apply the oil. Better hygiene means better results.
3. Patch test first
Even though it’s safe for most skin types, it’s always smart to do a patch test before using it near your eyes. Just dab a little on your wrist and wait 24 hours.
How to Apply Castor Oil Safely on Eyelashes

Can Men Use It Too?
Of course! Lashes don’t discriminate. Whether you're a man looking to fill out sparse lashes or just want better definition, castor oil works for everyone. Just follow the same routine and stick with it.
Potential Risks and Precautions
Now here’s the honest truth. While castor oil is generally safe, you need to use it right.
Things to watch out for:
- Don’t use it inside your eyes. If it gets in, rinse thoroughly with cold water.
- Don’t apply too much. A thin layer is more than enough. Overloading may cause puffiness.
- Stop using it if you get irritated. Though rare, discontinue use if you experience redness, itching or blurred vision.
And yes, only go for pure oils, preferably USDA-certified organic like the one from Soulflower.
What Kind of Results Can You Expect?
Okay, now for the question you really care about.
Realistically, here’s what happens:
- Week 1 to 2 – Your lashes feel more hydrated and flexible.
- Week 3 to 4 – You’ll notice lesser lash fall and some volume.
- Week 5 to 6 – Sparse areas will start filling out. Curling and defining your lashes will feel easier.
- Week 7 to 8 – Your lashes look naturally longer, fuller, and more fluttery.
No gimmicks. Just consistent care with a product that actually nourishes your lashes from the root.
Lifestyle Bonus - Use It on Eyebrows Too
Yup, it’s not just for lashes. Dab a little on your eyebrows every night and watch them fill out in a few weeks. One product, double the magic.
