The Best Castor Oil For Eyelashes: Our Choices

Castor oil for eyelashes: buying and evaluation criteria

In this section we tell you what to look for when buying castor oil for eyelashes and how to evaluate different alternatives. Above all, you should pay attention to:

In the following, we would like to present these criteria in more detail.

Manufacturing process

The different production processes of castor oils are mainly distinguished between cold pressing and refining.

Cold-pressed castor oils have the highest active ingredient content of all castor oils.

Cold pressing is characterised by the fact that the crushed oil seeds are put into the oil mill in a cold state. The mill itself is also cooled during the extraction process. Pressing usually takes place in only one process step. Cold pressing is a gentle way of extracting oil.

On the other hand, refining is one of the less gentle processes. Here, the oil is hot-pressed in the first step. Compared to cold pressing, this results in a significantly higher oil yield. In the next step, the actual refining takes place. The oil is degummed, deacidified and steam-treated. Chemical solvents are used here, the residues of which may remain in the oil. For this reason, the oil is cleaned afterwards.

Refined oils are characterised by their lower price, but also by their longer shelf life. However, this is at the expense of the active ingredient content of the oil. High-quality castor oil is characterised by its strong yellow colour.

Organic certification

Some castor oils for eyelashes are certified organic. This means that not only the production process, but also the cultivation itself is carried out according to the highest standards.

This refers above all to the choice of fertilisers, which are selected in such a way that as few harmful substances as possible are absorbed by the castor plant.

You can recognise organic certification mainly by seals such as the seal of the Soil Association or other seals on the product packaging.

An example of a seal that indicates organic certification is the Soil Association seal. Most certified organic castor oils are cold-pressed oils. This means that when you buy an organic product, you can be sure that you are getting the best quality.


The quantities in which castor oils are offered sometimes differ significantly. Especially if you want to use the castor oil for your eyelashes, it is advisable to rather go for smaller package sizes.

On the one hand, you only use a relatively small amount of oil when applying it to the eyelashes, and on the other hand, cold-pressed castor oil has a limited shelf life.

However, if you decide to use refined castor oil, it is not a problem to buy a larger quantity, as the refining process extends the shelf life of the oil.

Type of packaging

Most castor oils for eyelashes come in a darkened glass or plastic bottle. This is not a coincidence, but a reaction of the manufacturers to the light sensitivity of the oil. You should therefore make sure that you buy castor oil in a darkened bottle.

Bottles made of violet glass offer the best protection against light.

Whether you choose a glass or plastic bottle is up to you. Glass bottles have a higher quality and are often more visually appealing. Nevertheless, plastic bottles also offer advantages, especially with regard to transport, for example when you are on a holiday or business trip.

If you decide to buy castor oil in a glass bottle, a bottle made of violet glass is recommended. Violet glass has the property of completely blocking visible light and thus optimally protecting your castor oil from light irradiation and ensuring the longest possible shelf life.


When using castor oil on eyelashes, it makes sense to check which accessories are included in the delivery.

However, many castor oils already come with different accessories to enable the widest possible range of applications and thus also the application to the eyelashes.

On the other hand, there are also oils that are only equipped with a pump cap or a pipette. If you decide to buy such a product, it is recommended that you also purchase an applicator kit to apply the oil to the eyelashes.

Castor oils for eyelashes: frequently asked questions and answers

In this part of the guide, we want to answer the most important questions that many buyers and prospective buyers of castor oil for use on the eyelashes have. We hope that this will make your decision to buy and use castor oil on your eyelashes a little easier.

What is castor oil for eyelashes?

Castor oil is extracted from the seeds of the castor plant (Ricinus communis), the so-called "miracle tree". The castor plant belongs to the spurge genus.

The origin of the plant species goes back to North Africa and the Middle East. Today, however, the plant can be found in all tropical regions of the world. The plant can grow up to a height of 13 metres.

The seeds grow slightly larger than a hazelnut. To produce one kilogram of castor oil, about 1800 seeds of the castor plant are needed. A cultivated area of one hectare yields up to 2000 kilograms of castor oil.

Who is castor oil for eyelashes suitable for?

Castor oil is suitable for anyone who is interested in cheap and effective care for their eyelashes. It should be noted that the aim is not to make the eyelashes grow faster, as this is genetically determined. Nevertheless, castor oil helps to make the eyelashes soft and supple and gives them a beautiful shine.

What are the different types of castor oil for eyelashes?

For the use of castor oil on the eyelashes, you must first decide between natural oils and oils with organic certification in the cold-pressed oils. However, you can also use refined oils.

Type Advantages Disadvantages
Natural castor oils High quality, good price-performance ratio, cold-pressed oil possibly not free of pollutants
Organic certified castor oils Very high purity and quality, cold-pressed oil, sustainable cultivation comparatively high price
Refined castor oils long shelf life, low price lower quality than cold-pressed oils

Naturally pure castor oils are characterised by a high content of active ingredients. Furthermore, the natural oils are mostly cold-pressed oils. The advantage compared to organic oils is a lower purchase price. To identify naturally pure oils, you can use keywords such as "naturally pure", "pure" or "pure".

It is true that organic oils are also obtained on the basis of cold pressing. However, care is taken during cultivation to avoid pollutants, which results in better purity in terms of pesticides compared to natural oils.

Refined oils are characterised by their low purchase price. However, important active ingredients are lost in the manufacturing process, which means that the effectiveness is lower than that of naturally pure and certified organic castor oils. One advantage of refined oils, however, is their longer shelf life. Thus, refined oils are especially suitable if the oil is not used very often.

How much does castor oil for eyelashes cost?

The price of castor oil for eyelashes clearly depends on the quality and manufacturer, but also on the accessories and quantity supplied. For application on the eyelashes, the usual amount is between 30 and 100ml.

In the 100ml bottle, natural castor oil is already available from about 4 euros. The most expensive set, which already includes accessories such as an eyelash brush for application, costs about 18 euros.

Art Price range
Natural castor oils (100ml) between 4 and 18 euros
Organic certified castor oils (100ml) between 7 and 20 Euro
Refined castor oils (100ml) between 5 and 8 Euro

Organic certified castor oils in the 100ml bottle are available from about 7 euros. However, depending on the manufacturer and the range of accessories, you can pay up to about 20 euros.

In comparison, 100ml of refined castor oil costs between approx. 5 and 8 euros.

What are the alternatives to castor oil for eyelashes?

There are several alternatives to castor oil for use on eyelashes. Among the most popular alternatives are other vegetable oils such as olive oil, almond oil or linseed oil. Vaseline is also a popular alternative.

Alternative Description
Other vegetable oils Besides castor oil, other vegetable oils such as olive oil, almond oil or linseed oil are also suitable for eyelash care. However, castor oil has a particularly moisturising effect
Vaseline Vaseline can also be used for eyelash care. However, especially with certified organic castor oil, you can be sure that you are only allowing natural ingredients to reach your eyelashes.
Sera for eyelashes There are many different serums for the care of your eyelashes. However, these are rarely purely natural products.

Furthermore, there is of course a wide range of eyelash serums that can also be used for eyelash care. In the following, we would like to introduce you to these alternatives in more detail.

How do I apply castor oil to the eyelashes?

The best way to apply castor oil to the eyelashes is with an eyelash brush, which is included in many castor oil products. If you don't have a brush handy, you can also apply the oil with your finger, a toothbrush or a lint-free cloth.

How often should I apply castor oil to my eyelashes and how long should I leave it on?

It is best to apply castor oil to your lashes every evening and leave it on overnight. You can then remove the excess oil the next morning with a cloth and clean water.

Can I apply castor oil to my eyelashes and wear contact lenses at the same time?

Contact lenses should be removed before applying the castor oil to your eyelashes.

A light film of oil may form on the eye overnight. This is easy to remove from the eye, but difficult to remove from a contact lens and can damage the material.

Does castor oil make eyelashes longer or stimulate eyelash growth?

Castor oil does improve the look of your lashes by making them shinier and smoother. However, castor oil cannot really lengthen your eyelashes or encourage them to grow. This is purely genetic.

Can I apply castor oil to my eyelashes during pregnancy?

Castor oil is thought to have labour-inducing properties, which is why you should avoid using it (for example as a laxative) during pregnancy.

Despite the external application on your eyelashes, you should always consult your doctor before using castor oil during pregnancy!

However, external use such as application to the eyelashes should also be avoided. In any case, medical advice should always be sought before using castor oil during pregnancy.

What other uses are there for castor oil besides on the eyelashes?

Besides its use on your eyelashes, castor oil has a variety of other uses. You can use castor oil not only on your eyelashes, but also on your hair, eyebrows, nails and skin. Another popular use of castor oil is internally for gastrointestinal problems.

The moisturising effect of castor oil can be used to make a hair treatment or to make the eyebrows look brighter and softer. The moisturising effect can also be seen when used on the nails. Thus, treating brittle or dry nails with castor oil can lead to a more beautiful nail appearance.

The oil can also be applied directly to the skin. The oil is said to have an anti-wrinkle effect. Furthermore, castor oil can help with pimples and alleviate skin problems such as redness or neurodermatitis.

For gastrointestinal problems, one to two tablespoons of castor oil are suitable as a digestive and laxative. However, there is also a wide range of capsule products that can be swallowed instead of the pure oil.


Castor oil is an inexpensive, in most cases high-quality and natural care product for your eyelashes. By treating your eyelashes with castor oil, you can easily get softer and shinier lashes.

Natural and certified organic oils should be preferred over refined oils, as these have a higher active ingredient content despite a somewhat higher price and, in the case of certified organic oils, are also free of harmful substances.

Besides its use as an eyelash care product, castor oil is also an effective alternative for the care of your hair, eyebrows, nails and skin. Just make sure that you do not use the oil if you are still wearing contact lenses or are pregnant.
