Does Castor Oil Help Lashes Grow?

Does Castor Oil Help Lashes Grow?

Raise your hand if you’ve ever applied coconut oil, petroleum jelly, or vitamin E oil on your lashes to try to make them longer. We thought so. When it comes to lengthening our lashes, we admit we’ll try just about anything. 

If you’re still rubbing the Vaseline out of your eyes and wondering why your lashes still look the exact same length they did before you gooped them, you might be considering the next alternative, castor oil. 

Before you head to Amazon Prime to grab a bottle, the team at Lashify® wants to help you understand why it might not be your best option. We’ll talk about how lashes grow, what can help nourish them and keep them strong, and why using DIY Lash Extensions™ can give you the look you want without dousing your lashes in strange oils and gels.

Lash Growth 101

Before you start down the internet rabbit hole of how to get longer lashes, it’s important to understand how hair growth affects your lash length in the first place. 

For instance, most people have lashes that are around 10 millimeters long or about ⅓ of the width of the length of your eye. It’s rare for someone to have longer lashes naturally, but lashes can be shorter than 10 millimeters.

Your natural lashes grow on a four-stage cycle. During the four phases of natural eyelash growth, your natural lashes naturally extend through the hair follicle and reach their full length before being shed and replaced by a new lash. 

Anagen Phase

The first phase of lash growth happens as a new lash pushes through the hair follicle and extends to its full, natural length. 

Catagen Phase

The second phase of lash growth is transitional. The natural lash stops growing, and the hair follicle closes around the lash to hold it into place. 

Telogen Phase

The rest phase of lash growth is the longest phase. More than half your lashes are in this phase at any given time. This phase can last for several weeks before the exogen phase. 

Exogen Phase

The exogen phase occurs when the hair follicle loosens to allow the natural lash to fall and be replaced with a new lash that is entering the anagen phase. 

The entire cycle takes anywhere from four to 11 months. Luckily, each lash is on its own cycle, so you aren’t losing all your lashes at once. Also, it’s completely normal to lose between one and five lashes per day, so even if you feel like you’re losing a lot of your natural lashes, you probably are losing a normal amount. 

What Causes Lashes To Fall Out Too Soon?

Lashes might fall out too soon or never reach their full growth potential if they aren’t nourished properly or if you are inadvertently doing something that could damage them and cause them to break. 

Here are several reasons why lashes might fall out sooner than they should. 

1. You Have a Vitamin Deficiency

Your natural lashes need vitamin B7, also known as biotin, to grow strong. Most people get plenty of B7 in their diets, but if you are deficient, your lashes may not grow very long, and they could even fall out in clusters. 

Symptoms of a biotin deficiency are: 

  • Thinning hair (everywhere, not just your eyelashes)
  • Dry, scaly skin
  • Peeling and brittle nails

If you suspect this could be the cause, increase your intake of foods like beef, eggs, salmon, sweet potatoes, and nuts. You can also use topical biotin products, such as eyelash serums or moisturizers, to help support natural lash growth. 

Pro tip:Lashify’s bonds all contain biotin and lavandula, which helps them support healthy, natural lashes.

2. Your Makeup Is Sabotaging Your Lashes

Sometimes, our own best efforts work against us. Ingredients in some eye makeup, especially mascara, can cause your natural lashes to become brittle and break. Formaldehyde is frequently found in mascara (and in some lash glues, but never in Lashify bonds). 

In addition to being a carcinogen, formaldehyde can cause serious allergic reactions and can make lashes brittle and dry.

3. Your Salon Lash Extensions Are To Blame

Everyone loves a full set of professionally applied lash extensions, but experts warn that if the glue contains certain ingredients, it could make lashes rigid and more likely to break (taking the extensions with them).

Don’t worry; you don’t have to give up your lash extensions to protect your natural lashes. Let’s talk about how to keep those lashes healthy and whether or not castor oil is the solution. 

Castor Oil: Hero or Hype?

Your bestie is currently obsessed with using castor oil for hair growth. You might be wondering if it would work for your lashes. 

Short answer? Probably not. 

What Is Castor Oil?

Castor oil is like any other seed oil extracted from plants (think olive oil or canola oil). The cold-pressed castor oil that you find in beauty products comes from the ricinus communis plant. The ingredient in the plant that is most associated with hair growth is ricinoleic acid. 

This is a fatty acid that is often used in cosmetic products to increase glossiness and shine, and it can do the same for your lashes, but it won’t necessarily make them grow any longer than their natural length. 

Where’s the Evidence About Castor Oil?

There’s no scientific evidence that castor oil will make your lashes grow. A few studies have shown that castor oil works as a prostaglandin D2 inhibitor. This means it might be effective in preventing certain types of hair loss, like male pattern baldness, but it does not mean that it will make your lashes grow or even that it will keep you from losing them. 

How To Use Castor Oil Step-by-Step

Because castor oil is a natural fatty acid, it can improve the look of your lashes, which could be a good solution for you if you want lashes that naturally look darker and shinier without using mascara. 

It’s worth it to use a cold-pressed, organic castor oil supplement that is specially formulated for use near your eye area. Using a cotton swab, apply a thin layer of castor oil to the lash line. You can use a clean spoolie to pull the oil through your lashes. You can apply castor oil to your lashes twice per day as part of your normal skincare routine. 

If you don’t want to use pure castor oil on your lashes, you can always opt for a lash serum that contains it. 

Are There Any Side Effects of Castor Oil?

Using castor oil for eyelash growth is generally safe, but if you have particularly sensitive skin, you could experience skin irritation. 

If you know you’re sensitive, try doing a patch test on your temple to see if you experience any discomfort before you commit to slathering it on your delicate eyelid skin, all in the name of long lashes. 

Keeping Your Natural Lashes Healthy

Keeping your natural lashes healthy and avoiding breakage isn’t hard, but you do need to know a few basic tips to make sure you’re primed for optimal lash & brow growth. 

1. Avoid Products That Contain Harsh Ingredients

We’re looking at you, waterproof mascara. Most of us don’t need that level of protection on a daily basis. Waterproof mascara is difficult to remove even with oil-based makeup remover, and it can make your lashes incredibly brittle and dry. 

2. Load Up on Lash Loving Ingredients

Lash serums may or may not make your lashes grow. However, you can look for products that contain lash-loving ingredients, like Lashify bonds. Our bonds are also soft-setting bonds, which means they never fully cure. This allows your natural lashes to remain flexible in a way that salon lash glues can’t. 

3. Upgrade Your Extensions

Salon lash extensions can cost you more than time and money; they can cost you your natural lashes if they aren’t applied correctly or if the glue causes your lashes to fall out. A better option? The Lashify DIY Lash Extension™ System. 

Lashify uses safe, lash-nourishing bonds to keep your natural lashes protected while you’re wearing our lighter-than-air Gossamer® lashes. Our Gossamers® are designed to be applied underneath your natural lashes, which helps keep your lashes from bending at the roots from the weight of extensions. 

The best part? You’re in control of your lash real estate. You can easily switch from lowkey to Russian volume in the same day or in the same week. The choice is yours.

Can the Castor, Keep the Lashes

No, castor oil probably won’t make your lashes grow, but it could make them shinier and more noticeable. For lashes that are ultra-defined, lengthy, and still healthy for your natural lashes, there’s only one solution. Lashify helps you get the lash looks you love while maintaining natural lash wellness.
