Hi there, in this article, we will answer the most asked question: does castor oil help eyelashes grow? Well as we all know castor oil is a natural and efficient solution. Thanks to its unique composition, castor oil thoroughly takes care of your eyelashes, giving them the health and beauty they deserve. I can testify to castor oil’s efficiency, as I myself have been using it for several months now.

As I mentioned in my other article, castor oil for your hair {head hair, lashes, brows}, I used to get styes on my eyelids quite often.  After having one surgically removed, my eyelashes no longer grew normally in that area.  Rather, they came in ingrown, curly, short, and it was painful to wear mascara. Now, thanks to castor oil, my pain is gone, and my lashes are longer and healthier than they have ever been!

So what steps should you follow to grow your lashes using castor oil, you ask?

Step 1: Purify your lashes (& your face)

The first step for keeping eyelashes (or skin) healthy is to thoroughly wash and rinse off your makeup every night! My styles developed because my hair follicles on my eyelids were getting clogged (makeup).

Now, even if I am exhausted (and I mean like e-x-h-a-u-s-t-e-d) I always take the time and effort to thoroughly clean my face before bedtime.

What are the risks if you don’t wash your makeup off?

  • Increased eyelash loss
  • Allergy development (mascara, for example)
  • Dry skin, acne.
  • Accelerated aging of the skin (especially due to eye makeup)

While you sleep, your body and cells need to “breathe.”  Removing your makeup every day purifies your skin, allowing it to breathe properly and by thoroughly removing traces of mascara, eye shadow, or eyeliner from your eyes will prevent increased eyelash loss, sty development, or other impurities.

When you wake up the next morning with your face and eyes feeling fresh, I promise you won’t regret spending that extra two minutes to clean your face the night before.

What’s more is that your face will already be fresh and ready for another day of makeup (or better, embrace your natural beauty and skip a day of wearing makeup – your lashes will benefit tremendously from taking a break in supporting all that mascara).

A simple way to clean your lashes

  1. Use 1 cotton ball per eye
  2. Dip it in your eye makeup remover and let sit a few seconds on your lashes
  3. Gently wipe away starting with inside corner eye and working your way outwards

Of course, you can use any makeup remover that you normally use, but specifically getting a gentle-solution eye makeup remover will greatly help to remove makeup (heavy, waterproof, or light) without damaging your eyelashes with harsh soap, for example.  You can even use castor oil to thoroughly purify your face.  However, a makeup remover (and using it daily) is the basic solution in order to avoid any eye problems.  By following only this step, you will already see an improvement in the length and health of your lashes.

Step 2: Castor oil is the natural product for your eyelashes

Now let’s move on to the specifics of how castor oil acts on your eyelashes.  Castor oil is extremely rich in fatty and omega acids.  Once applied, the castor oil will work deeply to nourish your lashes from root to tip, allowing your lashes overtime to grow thicker, longer, and healthier.

How to apply castor oil to eyelashes?

To achieve the best results, you can castor oil for eyelashes in the following three ways:

1. with the help of a mascara brush/tube (that is clean/empty)

This is the ideal application method, as using a mascara brush will evenly spread the oil throughout your lashes from root to tip. It also prevents you from using too much (which can be the case with a q-tip or finger).

2. or a clean q-tip (avoids getting fingers messy) –make sure to use very small amounts!–

3. or lastly, you can get a bit sticky and apply castor oil to your lashes with your finger

This is what I do just because I don’t have to waste a q-tip and because I lost my castor oil mascara tube in Nepal. I personally apply a small amount and massage them with castor oil each night after cleaning my face and then remove the castor oil when I wake up the next morning.

If you’re just starting this routine, start with applying castor oil to your lashes at least 3 times a week.  If you would like quicker results, apply more often and pay special attention to targeting the roots of your eyelashes. Of course, please adjust according to your needs or preference.

Conclusion: does castor oil help eyelashes grow?

Within a month and a half of using castor oil on my lashes, I found them to look and feel longer and healthier. In the beginning, I did my first-week applying castor oil 3-4 times. In the next couple of weeks, I upped my application frequency to 7x a week. About 5-6 weeks later I was truly noticing longer, healthier lashes.

Castor oil eyelashes results:

Here are the following results using castor oil on eyelashes:

  • Results within a couple of days: Eyelashes that look and feel soft, supple, and darker.
  • Results after one month+: Noticeable growth in length, thickness, and overall health.

I wear less and less mascara daily, because thanks to castor oil, I no longer need to use makeup to lengthen or make my lashes appear bold. That’s why I highly recommend you try using castor oil for your eyelashes, too!

It is the best natural solution to grow out your lashes and to keep them looking and feeling strong and healthy! It’s natural, inexpensive, and worth the small time and effort.

    • Hey Steven! Thanks for dropping by 🙂 Great to hear you’re using castor oil. Castor oil is also great for reducing visible scar tissue, so continue to massage castor oil on the area at least 2X a day for several weeks. Not only will you see eyebrow thickness as a result, hopefully your scar will diminish over time too.
