If your lashes feel thin, brittle, or just plain stubborn, you’re not alone. Finding a reliable lash growth solution often means spending too much money on serums that overpromise and underdeliver.
But here’s the good news: one simple, all-natural trick has been quietly helping people get longer, fuller lashes—and it doesn’t require a trip to the beauty aisle. All you need are two humble ingredients you probably already have at home.
This isn’t a miracle serum or a flashy trend. It’s a nourishing, DIY blend that supports healthier lashes using time-tested, gentle ingredients. And the best part? Many start seeing results in just one week.
Here’s how this natural lash routine works—and how to start using it tonight.
Why Vaseline and Castor Oil Are a Dream Team for Lashes & Brows
1. Intense Moisture for Lash Follicles
Vaseline acts as a sealant, locking in moisture and keeping lashes soft. When paired with castor oil—rich in fatty acids—it hydrates deeply to encourage healthy, nourished hair growth.
2. Boosts Natural Growth
Castor oil is a natural source of ricinoleic acid, which may improve circulation to hair follicles. A study published in the Journal of Cosmetic Science in 2003 linked this compound to improved hair shaft health and growth speed.
3. Helps Prevent Lash Fallout
Weak lashes tend to break or fall out. The conditioning combo of Vaseline and castor oil strengthens hair strands, helping reduce breakage and keeping your lashes intact longer.
4. Gentle Enough for Daily Use
Unlike harsh commercial serums, this blend is safe for most people to use nightly. It nourishes without the chemicals, making it a safer alternative for sensitive skin.
5. Adds Natural Shine and Fullness
Consistent use makes lashes and brows appear fuller, shinier, and healthier overall. It’s like a deep-conditioning treatment—but for your eyes.
How to Make and Apply This DIY Lash Serum
Creating this lash-loving blend at home takes just minutes and costs next to nothing.
You’ll Need:
- ½ teaspoon Vaseline (unscented petroleum jelly is best)
- ½ teaspoon cold-pressed castor oil
- Optional: 1 drop of vitamin E oil for an extra boost
Instructions:
- Mix all ingredients in a clean, small container until smooth.
- Cleanse your face thoroughly, removing all eye makeup and oils.
- Dip a clean mascara wand or cotton swab into the mixture. Remove any excess to avoid drips.
- Gently apply along the upper and lower lash lines, as if applying eyeliner. You can also brush it onto sparse areas of your brows.
- Leave it on overnight and rinse off with warm water in the morning using a gentle cleanser.
- Repeat nightly for 7–10 days for best results.
Quick Tips for Best Results
- Always use a clean applicator to avoid introducing bacteria.
- Store your DIY serum in a tightly sealed container and use it within 2 weeks.
- Don’t expect overnight miracles—most people begin noticing fuller lashes after 5–7 days of consistent use.
- Avoid double-dipping your applicator into the serum to keep it sanitary.
A Few Precautions Before You Start
Although this blend is generally safe, it’s still important to be cautious:
- Avoid getting the mixture into your eyes, as it can cause irritation or blurred vision.
- If you have sensitive skin, patch-test the mixture on your wrist and wait 24 hours before using it on your face.
- Those with eye conditions or who wear contact lenses should talk to a doctor before using anything near their eyes.
- Stop use immediately if you experience redness, itching, or discomfort.

It doesn’t take a high-end serum or expensive lash extensions to get beautiful results. With just two pantry staples—Vaseline and castor oil—you can nourish and protect your lashes and brows naturally. Stick with it for a week, and you just might be surprised by what you see in the mirror.
