Castor Oil for Eyelashes: Can It Really Make Your Lashes Grow?
Castor oil has become a go-to home remedy for short, thin, or brittle lashes. Here's what it actually does, how to use it safely, and what dermatologists say about the science behind it.
Why People Reach for Castor Oil
One of castor oil's most notable qualities is how quickly it absorbs. If your lashes are breaking, shedding, or just looking a little sparse, it's one of the simplest things you can try at home. Many people with thin, brittle, or short lashes use it specifically to help lashes look thicker, stronger, and longer over time.
Applying this serum consistently is meant to strengthen lashes, encourage new growth, and help you notice a visible difference over time.
| Ingredient | Amount |
|---|---|
| Castor oil | 1 teaspoon |
| Coconut oil | 1 teaspoon |
| Vitamin E | 2 capsules |
How to Make and Apply It
- Mix the castor oil, coconut oil, and vitamin E together well in a small bowl.
- Apply the mixture to clean lashes using a clean mascara wand.
- Wipe off excess oil from the wand before applying, to reduce the risk of oil getting into your eyes.
- Apply at night before bed, and rinse it off with water in the morning.
Picking the right bottle makes a real difference. Look for castor oil that's:
- 100% natural and sourced from the seeds of the castor plant
- Cold-pressed — check the label, since this process preserves more of the oil's natural properties
- Paraben-free, to avoid unnecessary added chemicals near your eyes
Step-by-Step Application
- Wash and dry your face and eye area before you begin.
- Dip a clean mascara wand or cotton swab into the castor oil and let any excess drip off.
- Starting from the inner corner of the eye, apply along the lash line, making sure lashes are fully coated.
- Repeat on the other eye.
- Leave it on overnight, and rinse thoroughly with water in the morning before applying any makeup.
- Repeat nightly — most people who stick with it start noticing a difference within about 2 weeks.
If oil gets in your eye: Don't rub it. Rinse gently with clean, lukewarm water for a few minutes. Mild, temporary blurriness or irritation usually settles on its own — but if stinging, redness, or blurred vision continues, remove any contact lenses and see an eye doctor rather than trying to treat it at home.
Is It Safe? What Are the Side Effects?
Used carefully and in moderate amounts, castor oil hasn't been shown to cause serious side effects on lashes. The main risk is applying too much or too close to the eye itself, which can cause temporary blurred vision or irritation if oil seeps in. Applying it with care and precision — a thin coat along the lash line rather than a heavy application — is the best way to avoid this.
What Does the Science Actually Say?
It's worth being upfront about this: dermatologists Dr. Mona Gohara and Dr. Joshua Zeichner have both pointed out that there isn't solid scientific evidence proving castor oil directly stimulates new lash growth. Dr. Zeichner has noted that what looks like "growth" may actually be the oil conditioning and lightly plumping the existing hair shaft, rather than triggering genuinely new hair.
That doesn't mean it's not worth trying — many people are happy with the way it makes lashes look and feel — just that it's more of a conditioning treatment than a clinically proven growth stimulant.
What Users Say
- Some users notice temporary blurriness right after applying, which is why applying at night and rinsing off in the morning tends to work best.
- Most people report being satisfied with the results, often noticing visibly longer lashes within about 6 weeks of consistent use.
- Occasional mild eye contact has been reported, without lasting irritation — though it's still best to rinse promptly if this happens.
- Beyond length, many say their lashes also look noticeably thicker and fuller.
- Some people alternate between castor oil, calendula oil, and almond oil, reporting good results with all three.
