How Does Castor Oil Work for Eyelash Growth?

The Ricinus communis plant yields castor beans, which are used to make castor oil. Because of its many health, cosmetic, and skin-benefiting properties, castor oil has a lengthy skincare history that dates back to ancient Egypt and India. Because the Ricinus communis plant is high in fatty acids, protein, antioxidants, and nutrients, castor oil is perfect for hydrating the skin, scalp, and hair.

Castor oil’s possible benefits for eyelash development are due to ricinoleic acid, a component of it. According to dermatologist Hadley King, MD, of New York City, the ricinoleic acid in castor oil may activate a receptor, increasing the body’s natural synthesis of prostaglandin.

Castor oil is mild, natural, and free of adverse effects, unlike synthetic lash serums that can contain harsh chemicals. Even though chemical-based serums could show effects quickly, stopping them can weaken the lash, causing redness or discomfort. Conversely, castor oil protects, moisturizes, and conditions lashes without causing any unfavorable side effects.

How to Choose the Right Castor Oil for Eyelash Growth

Choosing the correct castor oil can significantly impact your eyelash growth process, as not all castor oils are created equal.

• Cold-Pressed: The best choice is cold-pressed castor oil since it is extracted without heat, maintaining its abundant nutrients. Refined castor oil undergoes processing, removing potentially healthy ingredients.
• Pure and Organic: Since it will be so close to your eyes, you should use a clean formula made entirely of pure castor oil, preferably one with USDA organic certification.
• Jamaican Black Castor Oil (JBCO): You might also encounter Jamaican Black Castor Oil (JBCO), which contrasts ordinary castor oil. Roasted and deeper in color, JBCO has a higher pH and is excellent for fortifying hair, although it could be too thick for fragile eyelashes.

The best option for lash growth is regular cold-pressed castor oil, which provides moderate nourishment without blocking hair strands.

How to Use Castor Oil for Eyelashes?

Using castor oil for eyelashes requires precision with the amount you are applying and how much you are applying. You must apply castor oil and additional natural ingredients properly for best results.

There are certain factors that you need to keep in mind:

• Apply castor oil to clean eyelashes without mascara or other similar products.
• Wash your face thoroughly and clean the area around the eyes before applying the oil.
• If there is any irritation, wash everything off as soon as possible.

1. Castor Oil by Itself

As mentioned above, castor oil contains Vitamin E, ricinoleic acid, and effective nourishing and moisturizing properties. When used multiple times over a period of time, it boosts the growth of the eyelashes and helps strengthen them further.

Directions:

• Dip a clean mascara wand into the castor oil
• Apply the castor oil much like how you would apply the mascara
• Coat the eyelashes completely
• Leave it on overnight and go to sleep
• Wash off the remnant the following day

2. Castor Oil And Vitamin E

People commonly recognize that vitamin E helps develop hair by providing a natural defense against damaging UV rays, pollution, and free radicals that can damage hair follicles. Castor oil prevents lash breakage and thinning by deeply hydrating, strengthening, and nourishing lashes. They work as a potent combination to produce inherently longer, thicker, and healthier lashes.

Directions:

• Put two drops of vitamin E and 8 ml of castor oil in a small jar.
• Mix everything for a paste-like texture.
• Use a clean mascara wand to apply the mixture to the eyelashes, coating every strand with it.
• Leave it on overnight or for six hours, and rinse it off with water.
• For optimal results, try this DIY twice a week.

3. Castor Oil And Coconut Oil

One of the most common causes of brittle and thin eyelashes is a lack of hydration and moisture. If you have been suffering from something similar, the best way to combat the problem is to apply coconut oil along with castor oil.

The combination of essential fatty acids in both oils—castor and coconut—actually helps boost the overall nourishment the eyelashes require for growing longer and healthier.

Directions:

• Put two drops of coconut oil and five to seven ml of castor oil in a little container.
• Gently stir it. Apply the mixture to your eyelashes using a cotton ball or a clean mascara wand.
• Four hours later, wash it off.
• Try this two times a week.

4. Castor Oil And Olive Oil

Olive oil is a rich source of antioxidants and vitamins A and E. Applying olive oil to your eyelashes is healthy. When you combine it with castor oil, the advantages are doubled, allowing your lashes to absorb the goodness of both these amazing oils.

Directions:

• Fill a bottle with two tablespoons each of castor oil and olive oil.
• Make sure the oils have been thoroughly mixed.
• Apply this combination to your upper and lower lash lines using an eyeliner brush or a clean mascara wand.
• After leaving it on all night, take it off with a makeup wipe the following day.

5. Rosemary Oil and Castor Oil

Rich in essential vitamins, minerals, and fatty acids, castor oil helps strengthen and nourish hair follicles by supplying them with needed nutrients. On the other hand, Rosemary oil improves blood flow, guaranteeing the best possible supply of nutrients and oxygen for lash development. Combined, they form a potent mixture that naturally increases eyelash thickness and health.

Directions:

• Stir thoroughly to combine three drops of rosemary oil with the five ml castor oil.
• Apply this solution to your lashes with a clean mascara wand.
• Leave it for at least six hours or overnight.
• Use running water to rinse it off.
• Use this recipe once a week.

6. Castor Oil And Almond Oil

Essential lipids, calcium, magnesium, and vitamin E are abundant in sweet almond oil. Over time, it gives your lashes more luster and sheen, which makes them longer, thicker, and more resilient. As it bridges the space between cuticle cells, it also aids in making the hair more elastic. Almond and castor oils work well together to improve the appearance of your lashes.

Directions:

• Fill a jar with two tablespoons each of sweet almond and castor oil.
• After mixing the oils, apply one coat of this combination to your lashes using an eyeliner brush or a clean mascara wand.
• For optimal effects, leave it on all night.

7. Egg White, Glycerin, and Castor Oil

Make your own natural eyelash serum with just two essential items from your kitchen! Because of its deep moisturizing qualities, glycerin is well known for keeping lashes moisturized and healthy. In the meantime, lashes are strengthened and nourished by the proteins and amino acids found in egg whites, which encourage thicker, longer, and healthier growth.

Directions:

• Fill a small bottle or jar with castor oil.
• To the oil, add two drops of glycerin.
• Add two drops of egg white and mix.
• Apply this homemade serum to your upper and lower lashes with a clean mascara wand.
• Keep it on for a few hours or overnight.

8. Castor Oil, Coconut Oil, and Vaseline

Petroleum jelly is an excellent moisturizing and conditioning product that helps moisturize and shield dry, brittle lashes from damage. Coconut oil, rich in vitamins, antioxidants, and vital fatty acids, deeply nourishes lashes, making them shinier, smoother, and darker. When combined, they make the ideal natural lash care product!

Directions:

• To make this serum, take a small, clean container or jar.
• Fill it with one part castor oil, one part coconut oil, and two parts vaseline.
• Mix the ingredients thoroughly.
• Apply one coat of this combination to your upper and lower lashes using a clean mascara wand or an eyeliner brush.
• Leaving it on all night.
• Use makeup removal wipes to remove it in the morning.

How Much Time Does Castor Oil Take to Grow Eyelashes?

Applying castor oil consistently each night is the only way to get noticeable and beneficial outcomes. Since eyelash growth is a gradual process, patience is essential. It typically takes three to six months for lashes to regrow and show appreciable length, thickness, and attractiveness gains.

Frequent application guarantees that you deeply nourish and strengthen hair follicles, minimizing breakage and encouraging longer, thicker lashes. For optimal results, make castor oil part of your daily nighttime routine!

Castor Oil for Eyelashes – Side effects

Castor oil is not known to have serious adverse effects when applied to eyelashes in moderate doses. Many people take castor oil regularly without any problems for their eye health. However, when too much oil gets into the eyes, it can cause moderate discomfort and blurred vision.

A study found that castor oil’s ricinoleic acid may be detrimental to eye cells. Lab testing showed that castor oil may cause oxidative stress and cell death in human eye cells.

So, use it in moderation and apply a thin layer to reduce the chances of the oil leaking into the eyes.
