Yes, you heard that right. Castor oil is the new hype product that is said to transform thin and brittle hairs into real Bambi lashes. Admittedly, castor oil does not exactly have a glamorous image.

At first glance, there is not much to suggest that this inconspicuous oil also offers real benefits for beauty care. As a skin care product, it is said to give dry skin a real moisture boost and fight stretch marks and cellulite. Used as hair care, it is said to turn stubborn strands into truly shiny manes.

Castor Oil for Eyelashes – What It Is

Castor oil is a vegetable oil obtained from the valuable but highly toxic seeds of the castor plant. The castor plant, even named “Poisonous Plant of the Year” in 2018, is also called the “miracle tree” due to its rapid growth. The tree with its bright red, peculiarly jagged, spiky fruits can grow up to 5 meters per year. Actually, the castor plant is not a tree but an annual, herbaceous shrub. It originates from northern Africa and is found in all tropical regions. The name of the plant comes from Latin: ricinus means tick. Viewed from above, the poisonous seeds of the plant, with a little imagination, look like giant ticks.
The castor seeds are highly toxic due to their high ricin content. Just ten seeds can cause severe poisoning in adults if swallowed. Most of the castor oil is produced in India, China, and Brazil. The extraction of the oil is elaborate: it is carefully pressed from the (peeled) castor seeds, and the toxic ricin must be neutralized by boiling. One liter of castor oil requires 8,000 (!) seeds of the miracle tree.

Castor oil itself is, of course, not toxic. It is relatively viscous and usually yellowish or transparent but can also be black depending on the source. Previously mainly used as a lubricant and as a component of varnishes, castor oil today also plays a large and successful role in the cosmetics industry: whether in creams or as a care product for skin, hair, and eyelashes – castor oil has long since moved from the boring corner to the top tier of beauty tools with potential. When buying, you should be clear about what purposes you want to use the castor oil for: in pharmacies, you mostly find filtered castor oil intended as a laxative, which does not contain the ingredients important for skin and hair care. For this reason, it is usually cheaper than a high-quality, cold-pressed castor oil used for skin care. For external skin care, however, you should always make sure to use a high-quality, cold-pressed, and untreated castor oil, as it still contains the important nutrients you need for the care of your skin, hair, and eyelashes.
Castor Oil for Hair and Eyelashes – How Effective Is It?
Castor oil was already used in ancient Greece for internal and external applications. Castor oil has a very high vitamin E content. Because it penetrates deeply into the skin, it is often used to treat dry skin, skin inflammations, acne, and even warts. However, if you decide to use castor oil as a new body lotion substitute, you should think twice: due to its heavy and rich texture, the oil takes quite some time to absorb. Therefore, slipping into jeans immediately afterward is difficult. For skin care, you should also start with a small dose and observe how your skin reacts to the very rich oil. Generally, it is advisable to use castor oil in "courses," i.e., only for a few weeks (e.g., during the winter months) to bring dry skin back into balance. Too long and too frequent use of heavy oils can cause some skin types to dry out severely. A vicious circle.

Full, healthy, dense, and shiny hair – who doesn’t dream of that?
Hollywood star Charlize Theron no longer just dreams but has been making flowing hair a reality with an inconspicuous beauty helper for some time: the blonde beauty swears by castor oil for her hair, which not only gives it a healthy shine but also more density, strength, and volume. https://www.peoplemagazine.co.za/celebrity-news/international-celebrities/charlize-theron-insists-castor-oil-is-the-secret-to-great-hair/
For dry, damaged, and broken hair, a regular treatment with castor oil works wonders. Leaving the oil to work overnight on still slightly damp hair and rinsing it thoroughly the next morning results in healthy, shiny, and easily combed hair. But castor oil not only offers real benefits for skin and hair – beauty bloggers and Instagram stars have recently discovered the oil for their eyelashes and eyebrows and tirelessly post their evening routine extended by castor oil application: removing makeup, applying castor oil to eyelashes and eyebrows, and going to sleep. The result? (allegedly) longer, denser, and more resilient lashes. But can this really be true, or are bloggers and influencers just making us believe something we want to believe?

Does castor oil show effects? The answer is: Yes, castor oil shows effects! Castor oil helps achieve more beautiful eyelashes! Although the oil cannot really speed up natural growth, the care and moisture it provides with absolutely regular use make the lashes healthier and thus more resilient. Regular makeup application, removal, or curling with an eyelash curler can no longer harm the delicate hairs.
Castor Oil: Effects and Application

Castor oil forms a film on the eyelashes, providing them with moisture and care and protecting them from moisture loss. This makes the lashes more supple, stronger, and more resistant to external influences. The skin around the lashes is also cared for by the application of castor oil; fine lines disappear, and the formation of wrinkles is prevented. Since well-cared-for, optimally moisturized lashes are less likely to break, after our castor oil care trial (castor oil should be applied continuously for at least 8 weeks), we look back at full, dense, sexy lashes. Here’s how it works: once daily, in the evening after cleansing the eye area, apply castor oil to the lashes with a cotton swab or an old (of course clean) mascara brush and then, if necessary, remove excess oil with a cotton pad. Eyebrows should not be forgotten during application: applying daily to the eyebrows also provides care and shine to the fine hairs.
Side Effects of Using Castor Oil
Castor oil is generally very well tolerated. Since the oil is usually free of chemical additives, application around the eyes is generally unproblematic. However, you should discontinue use at the slightest sign of irritation or allergy and rinse your eyes immediately with lukewarm water. Because the oil forms a slight film on the eye, it should definitely be applied in the evening before going to bed. Contact lenses should also be removed before application. In general, only oil of tested and flawless quality should be used.

Castor Oil During Pregnancy
Pregnant women should not take castor oil. In the so-called “contraction cocktail,” a natural but by no means harmless method to induce labor, apricot juice, alcohol, and castor oil are included. The alcohol is there to dissolve the castor oil; the “cocktail” is mainly given when the actual due date has long passed. This should never be taken independently but always in consultation with a midwife!
After birth, castor oil can also be used to care for stretch marks: after showering, massage the castor oil into the still slightly damp skin and remove excess oil with a cloth.
Alternatives to Castor Oil
Thanks to its high vitamin E content, castor oil has proven itself in the past as THE number one eyelash boost helper. Of course, there are many other oils with which eyelashes can be cared for. Many also swear by other oils for eyelash care, such as olive oil, linseed oil, or almond oil. Vaseline is also regularly used in some bathrooms for daily eyelash care. However, Vaseline is made from petroleum and has nothing to do with natural products like castor oil. Olive oil, the Mediterranean classic, is no stranger in beauty care and is repeatedly mentioned as a secret care tip for brittle lashes. Olive oil not only tastes delicious on salads and is therefore a standard in every kitchen. Unlike almond or linseed oil, we all have a bottle of olive oil in the kitchen. So reaching for olive oil for a natural eyelash boost and quick care is obvious. But can olive oil really compete with castor oil for eyelash care? A comparison:
Incredible Lashes on the Way: Castor Oil or Olive Oil?

While olive oil is a classic edible oil, this is naturally not the case with castor oil. Castor oil has been used for centuries for digestive complaints and as a laxative. Both oils stand out due to their high vitamin E content. When a high-quality oil is used, side effects are hardly to be expected with either oil. Castor oil, unlike olive oil, has a rather creamy consistency. When applied to the skin, you initially feel – unlike the rather light consistency of olive oil – that it sticks and will never absorb. Its heavy and rather sticky consistency is also the reason why you should apply castor oil (ideally two whole hours) before going to bed. Castor oil also has a slight but very distinctive smell that you naturally have to like. Olive oil contains, in addition to a lot of moisture, important antioxidants that counteract damage caused by free radicals. Here too, quality plays an important role in beauty care: gently cold-pressed oils in organic quality are free from pesticides and fertilizers and contain no harmful additives. The quality of olive oil is divided into three classes: “extra virgin” refers to an oil of the highest quality, obtained directly from olives without any chemical treatment or heating. “Virgin olive oil” refers to second-class olive oils. The term “olive oil” without further additions includes olive oils made from a mixture of refined (i.e., industrial) and virgin (i.e., cold-pressed) oil and corresponds to the lowest category. The color here is rather pale, and the consistency somewhat thicker. Olive oil also has a smell that is perceived as pleasant or unpleasant depending on taste.
For external use, the question of particular interest is – which ingredient stimulates eyelash and eyebrow growth?
The answer is: None. Neither of the two oils contains ingredients that make eyelashes and eyebrow hairs longer. However, both contain valuable nutrients essential for the care of our fine hairs. Only well-cared-for, moisturized eyelashes and eyebrow hairs appear visually fuller and longer and do not break prematurely. Preventing premature eyelash breakage can lead to longer, fuller, and denser lashes in the long term, even if none of the ingredients in the two oils is directly responsible for lengthening.

Which of the two oils is preferred for eyelash care is ultimately a matter of taste. The application is always the same: carefully apply the oil to eyelashes and eyebrows with a cotton swab or an old, clean mascara brush and do not remove it. The eye area should, of course, be thoroughly cleansed of makeup, dirt, and sweat beforehand. Let the oil work overnight and remove excess residue in the morning with lukewarm water.
For those who find this too much effort: nowadays, there are also many practical and high-quality eyelash care products Link to: https://jeuxlore-cosmetics.de/products/jeuxlore-lanox-fleur-eyelash-care-complex-8-ml
that contain castor oil and at the same time have a practical applicator. This makes application particularly easy and trouble-free – nothing spills!
Castor Oil vs. Eyelash Serum
Longer, denser, fuller, and more supple lashes with natural oil? Many swear that castor oil lengthens and thickens eyelashes and eyebrows. However, these are rather the side effects of persistent and regular extra care: well-nourished, moisturized lashes are more resistant to external influences. They no longer break so easily and better withstand daily mechanical procedures such as daily makeup, curling with an eyelash curler, or daily makeup removal. Castor oil is therefore an important part of daily eyelash care. There are now several eyelash serums. However, it is also of the highest priority here to choose a high-quality product that impresses not only with its quality and transparent manufacturing process (link here: https://jeuxlore-cosmetics.de/pages/company)besticht but also convinces with positive customer, media, and influencer feedback. Superlative Lash is THE eyelash serum trusted by hundreds of thousands of customers worldwide that transforms short and thin lashes into real eye-catchers. For long, dense, strong, and resilient lashes, the combination of an eyelash serum and additional care with castor oil is perfect. Nowadays, there are eyelash products with castor oil that make handling particularly easy and application flawless. For example, the Lanox Fleur Eyelash Care Complex has a rubber brush that reaches every lash from root to tip and supplies valuable moisture. Additionally, the included vitamin E provides further care.
But for everyone who likes to style their eyebrows, applying an eyelash serum and additional care is essential to have full, bushy eyebrows: apply the eyelash serum, e.g., Superlative Lash, once daily also to the eyebrows or areas where hairs should grow and let it absorb briefly. Just before going to bed, gently brush the eyebrows with a rich, castor oil-containing care product, e.g., the Jeuxloré Lanox Fleur Eyelash Care Complex.
