When we want to deeply nourish our hair, we immediately think of the wonderful castor oil . All over the world, castor oil continues to be used in hair restoration therapies, to soften and soothe the scalp. But is that all it is used for?

In short

  • Cold-pressed castor oil is thick and rich in ricinoleic acid.
  • A classic for nourishing hair and scalp; also used in skin care.
  • For cosmetics, prefer organic, cold-pressed oil – not cheap refined oil.

Before we get to the interesting part, we would like to note that here we will only consider the qualities of the oil from organic production of the raw material and its subsequent cold pressing. Cold-pressed castor oil is incomparable in quality to the widely available cheap varieties for the pharmaceutical industry. These variants are heated, refined and, most importantly, the purity of the beneficial fatty acids is permanently reduced.

Castor oil

Although castor oil production is one of the cheapest in the world, cold-pressing technology yields only about 45% yield, after filtering the seeds of the first quality. Therefore, high-quality castor oil is not cheap. Pure oil is thicker than other base oils, light yellow or colorless in color, does not dry out and does not form a film on the skin. You should know that it does not smell very pleasant, but you can always add a drop or two of your favorite essential oils . When you first encounter it, do not be surprised by its aroma, it is not spoiled, it just smells like that because of the high content of ricinoleic acid. We will talk about it a little later in the article.

The oil is one of the most commonly used ingredients in the cosmetic industry, as it gives creams their snow-white color and shine to eyeshadows, lipsticks, and other makeup. Its many forms include: oils, shower gels , lotions, soaps, natural shampoos , conditioners, and even candles.

History of castor oil

Although many people initially considered the Ricin plant dangerous, the fine oil produced from its seeds possessed numerous benefits that soon became known worldwide. The benefits of castor oil were discovered and popularized by Edgar Cayce, who is considered the "father of holistic medicine." He introduced the public to its healing properties related to a number of health problems, and in many places the oil is also known under the name "Palm of Christ".

Ricinus communis , commonly known as the castor oil plant, grows in Mediterranean regions, as well as in tropical regions of Africa and India. Castor oil was historically used as a laxative, in pregnant women to induce labor, and to increase the flow of breast milk. In ancient Egypt, castor oil was used in wicks to light lamps, and seeds of the plant have been found in tombs dating back to 4000 BC.

Benefits of castor oil

Skin benefits

Reduces Acne: Castor oil boasts antimicrobial and anti-inflammatory properties that make it a powerful ally against acne. By inhibiting the growth of acne-causing bacteria and reducing inflammation, it can help clear up acne and promote a clearer complexion.

Hydration and Moisturization: Castor oil’s richness in fatty acids, especially ricinoleic acid, offers excellent moisturizing properties for the skin. These fatty acids help retain moisture, making it a suitable choice for people with dry or dehydrated skin.

Skin Tone and Even Out Skin Tone: The fatty acids in castor oil promote the growth of healthy skin tissue, potentially helping to even out skin tone. Applying it can lead to a smoother, more even complexion.

Anti-inflammatory properties: The ricinoleic acid in castor oil has anti-inflammatory properties that can be helpful in soothing irritated skin. It can provide relief for a variety of skin conditions, including psoriasis, eczema, and dermatitis.

Antioxidant Protection: Castor oil is rich in antioxidants that help protect the skin from free radicals that can lead to premature aging. These antioxidants fight oxidative stress and help promote healthier, more youthful-looking skin.

Natural Cleanser: Castor oil’s triglycerides serve as a natural cleanser that effectively removes dirt and impurities from the skin. Regular use can help maintain a clear and radiant complexion.

And one more thing very useful in the summer. The anti-inflammatory properties of castor oil make it suitable for the relief of sunburned skin. Its moisturizing abilities can also reduce unpleasant flaking/peeling if you've gone too far in the sun. Mix castor oil, aloe vera gel, vitamin E and a drop or two of lavender in a dropper bottle. Apply to the affected areas with light massaging movements.

Benefits for hair

Hair Nourishment: Castor oil is often used as a hair conditioner. It is particularly effective in hydrating and improving the texture of hair, making it softer and more manageable.

Strengthening Hair: While scientific evidence supporting hair growth is limited, castor oil may help strengthen hair, reducing the likelihood of breakage. Its rich fatty acid content and emollient properties make it an excellent choice for healthier, more resilient strands.

Scalp Moisturizing: Castor oil’s moisturizing properties extend to the scalp as well. It can help relieve dryness and flaking, providing relief from common scalp problems like dandruff.

Strengthening Eyebrows and Eyelashes: Castor oil is a popular natural remedy for stimulating the growth and thickness of eyebrows and eyelashes. Although it has not been scientifically proven, its moisturizing effects may improve the condition of these delicate hairs.

Hair shine: Regular application of castor oil can add a natural shine to your hair, making it look shiny and vibrant.

Preventing tangles: Castor oil can be used as a detangler for unruly hair, preventing knots and tangles from forming.

Benefits for the scalp

Dandruff Control: The moisturizing properties of castor oil make it a popular choice for combating dandruff. It helps hydrate the scalp and reduce flaking.

Relieves dry scalp: If you suffer from a dry and itchy scalp, castor oil can provide relief. It soothes the skin, relieving discomfort.

Scalp massage: Massaging the scalp with castor oil can improve blood circulation, which can stimulate hair growth and promote a healthy scalp environment.

Cleansing effect: The natural cleansing properties of castor oil can help remove dirt and excess oil from the scalp, maintaining a clean and balanced scalp.

Castor oil can positively affect hair by stimulating circulation, including hair growth, while maintaining its moisturizing properties. With its antifungal properties, castor oil can treat scalp infections by eliminating bacteria and microorganisms that can cause hair loss or dandruff. 

This is the place to tell you that the oil has a very thick and greasy consistency. Therefore, we always recommend when applying to the scalp to be with a pipette for better control. You only need a drop or two, don't overdo it! If you do a hair mask at night and you put too much of the oil on, you'll want to scream in the bathroom in the morning because you won't be able to wash it off easily. So trust us, our family regularly uses castor oil to nourish the hair and the recommended dose is up to 3-4 drops depending on the condition of the hair.

Applied to the scalp, castor oil can also delay the appearance of white hairs, as it can prevent further loss of hair pigment. With its moisturizing properties that lock in moisture, castor oil can treat dry and damaged hair, making it thicker, shinier, softer and smoother. Don't worry if your hair tends to get greasy, you can safely use the oil as a mask. A proven recipe for shine and scalp nourishment.

Another great use is for lengthening and thickening eyelashes. Try applying it at night before bed for a month and you will see how your eyes will look more fluttery. :) But its benefits are not only for hair and eyelashes. Castor oil can help your nails grow and become healthier. It also nourishes cuticles and dry hands wonderfully, especially during the harsh winter months. Rub a few drops of oil on your cuticles, nails and hands and you will immediately notice their softening.
