Benefits of Using Castor Oil for Eyelashes

Castor oil is so affordable that you can buy a lot of it without breaking the bank. Other than its budget-friendly price, the various benefits of using it for eyelashes make it a great alternative to mascaras. You can actually replace your mascara with castor oil. It will give you naturally lustrous lashes.

Every hair in your body has a natural growth cycle – they grow and fall out. However, there are factors that can make them thin or fall out. This happens when there is not enough nourishment to hair. The follicles get thinner until they are completely cut off from the receptors that receive and deliver nutrients to the strands. This leads to thinner and weaker hair that may break or fall. Other factors that make your eyelashes thinner are: rubbing your eyes, using damaging mascaras, and plucking eyelashes (yes, some people do this). In order to maintain the ideal thickness and length, use castor oil for eyelashes. You can strengthen your eyelashes by applying castor oil daily. Since the oil is versatile, you can apply it in various ways.

Castor oil is the perfect product to apply to your eyelashes if you want to make them longer and thicker. It helps fortify individual strands so they don’t break easily. Using castor oil for eyelashes stimulate the follicles to grow longer and stronger strands as well.

How to Use Castor Oil for Eyelashes

Take advantage of how versatile castor oil is. There are many ways that you can use it for eyelash care. Here are three different ways to apply castor oil for hair growth. Repair, strengthen, and protect your eyelashes from thinning with these castor oil uses.

Eyelash Growth Serum

You can get longer and thicker eyelashes even without mascara. Naturally voluminous lashes is possible with castor oil serum. You can apply pure castor oil or try the serum recipe we have below. The serum absorbs deep into the follicles to promote hair growth. In order to get the best results, make sure to follow these directions.


  • 2 tablespoons of pure castor oil
  • 1 tablespoon olive oil or almond oil
  • 1 tablespoon aloe vera gel
  • Clean mascara bottle
  • Eyelash applicator or Q-tip

Pour all these ingredients into a small mascara bottle and mix.

How to Apply

  1. Take the applicator or Q-tip and dip it in the bottle. Make sure not to soak for too long to avoid saturating the applicator in oil. Remove excess oil.
  2. Apply to the roots of eyelashes starting from the inner eyelid and brushing outwards. Do the same for the bottom eyelashes. Next, coat your eyelashes evenly in the oil in the same way that you apply mascara.
  3. Leave them on eyelashes overnight for best results.

It is important that you apply the serum to the roots of eyelashes because that is where the follicles are. Simply applying them to eyelashes does not promote hair growth.

How it Works

Castor oil is chock full of vitamins and minerals that stimulate the growth of healthy eyelashes. It contains around 85-95% ricinoleic acid. This substance gives castor oil therapeutic effects. The anti-inflammatory properties of castor oil prevent the follicles from contracting. As follicles get thinner, the hair receives less nourishment. This can lead to the deterioration of hair follicles until it gets completely cut off from the source of nourishment. This makes hair fall out. The same thing happens to your eyebrows, especially for women who are in their 40s. This is often an effect caused by high levels of dihydrotestosterone (DHT). Since castor oil is a DHT-blocker, it prevents DHT from binding into hair follicles and stopping hair growth.

Eyelash Primer

Applying mascara to already dry lashes increases the risks of making them brittle and prone to breakage. By applying castor oil serum, you can seal the moisture to hair and improve its thickness. This increases the resilience of eyelashes too. Here’s how to use castor oil as a primer.


  • ½ tablespoon pure castor oil
  • ½ tablespoon vitamin E oil
  • Clean mascara bottle
  • Mascara wand

Mix castor oil with vitamin E oil in the mascara bottle and store away from direct sunlight.

How to Apply

  1. Take the mascara wand and dip into the mixture of oils. Remove excess oil by running the wand against the rim of the bottle as you take it out.
  2. Apply to eyelashes starting from the roots and in an upwards motion. Make sure not to apply too much to avoid seepage. Repeat on the bottom lashes.
  3. Let the oil absorb through eyelashes for a minute before you apply the mascara.

How it Works

Mascaras can damage and cause breakage to your eyelashes. Cleansing your face and applying makeup every day can dry your eyelashes. When you coat it in mascara, the product can worsen the dryness of the strands. This increases the risk of eyelash breakage. But castor oil can prevent it by sealing the moisture to hair. The oil is found to have high levels of essential fatty acids that absorb well into hair. It coats it in thick moisture as well to fortify the strands. The vitamin E and protein in castor oil will protect and repair eyelashes so it doesn’t break easily.

Reduce damage to your eyelashes by cutting back on the number of makeup products that you apply to eyes. Don’t worry, you can still make your eyelashes look full and voluminous by using castor oil. Here’s how you can apply it as natural mascara.


  • Castor oil
  • Mascara wand
  • Tissue or soft cloth

How to Apply

  1. Take the mascara wand and dip it in castor oil. Remove excess oil to avoid making a mess.
  2. Apply to eyelashes starting from the roots to the tips. Do this until eyelashes are fully covered and repeat the process on lower lashes.
  3. Let the oil dry for a minute and gently pat with tissue. Apply a second coat to get thicker and shinier eyelashes. You can apply just one coating, but if you want greater volume, this does the trick.

How it Works

Castor oil has a thick consistency that coats each strand of eyelashes in moisture. As moisture absorbs into the strands, it increases the volume and body of your eyelashes. This gives you natural full lashes that stand out. It defines the curve of your lashes as well. Using castor oil helps restore the health and strength of eyelashes.

Pair up thick eyelashes with bold brows that give you personality. Just like with your lashes, you can also use castor oil for eyebrows. It has the same hair growth stimulating effects that give your brows thicker volume. Apply pure castor oil or mix it with other oils to get great results. Since you are applying the oil near your eyes, make sure that buy castor oil with high quality to avoid risks and to get the best results.
