Discover six amazing castor oil benefits for skin and hair and learn how to use pure castor oil to promote hair growth, combat dry skin, and soothe chapped lips.
What is castor oil?
Castor oil is a vegetable oil derived from the seeds of the castor oil plant native to tropical regions of Africa and India.
This pale yellow oil has a distinct bitter taste and a slightly pungent odor and can be ingested in small amounts. However, it’s not classified as an edible oil used for culinary applications.
Castor oil has many health benefits and has been used for centuries as a natural laxative to relieve constipation, improve gut health, and induce labor.
Research published in Lipid Insights found that as much as 90 percent of the fatty acids in castor oil comprise ricinoleic acid, a lipid-like compound with potent moisturizing, anti-inflammatory, and antibacterial properties.
Due to its molecular structure, ricinoleic acid is readily absorbed and penetrates deep into skin layers, where it can help improve hydration, reduce inflammation, and promote overall skin health.

The Therapeutic Benefits of CASTOR OIL (Skin/Face/Hair)
Benefits of castor oil for skin and hair
The use of castor oil as a beauty product can be traced to ancient Egypt, where it was widely utilized to moisturize skin and maintain healthy hair.
In recent years, castor oil has experienced a resurgence in popularity as a natural remedy for managing skin problems, improving a dry scalp, and promoting hair growth.
Here are six benefits of using castor oil to promote radiant skin and healthy-looking hair.
1. Keeps skin hydrated
Ricinoleic acid has a unique chemical structure with hydrophilic properties, meaning it attracts and retains water molecules.
Because castor oil can penetrate deeper layers of the skin, ricinoleic acid's water-binding effects help maintain optimal hydration levels, improve skin elasticity, and support overall skin health.
This has been confirmed by research published in Molecules, summarizing, ”Castor oil promotes an increase in healthy pores and skin tissue through moisturizing, hydrating, and cleansing.”
Castor oil also stimulates collagen production and cell regeneration, which may explain why regular application can help reduce the appearance of fine lines and wrinkles.
2. Soothes skin irritation
Castor oil can help soothe irritated skin and improve skin rashes and breakouts, especially those caused by bacterial or fungal overgrowth.
“Ricinoleic acid has potent antimicrobial properties as it disrupts the cell membrane of microbes,” explains Dr. Berg. “This can help alleviate various skin infections such as athlete's foot, jock itch, and ringworm.”
In addition, castor oil forms a protective barrier on the skin's surface, which helps prevent pathogens from penetrating the skin and protects against harsh environmental irritants that can cause dryness, inflammation, and other skin issues.
3. May reduce dark circles beneath the eyes
Scientific evidence suggests that castor oil may help improve the appearance of dark circles under the eyes.
A study published in the Journal of Cosmetic Dermatology found that castor oil cream is an effective alternative for treating infraorbital hyperpigmentation, widely known as dark circles beneath the eyes.
Castor oil has also been found effective in reducing dark spots by encouraging the growth of new, healthy skin cells to replace old pigmented ones.
4. Can reduce the appearance of scars and stretch marks
You can apply castor oil to improve the appearance of scars and stretch marks.
Regularly massaging affected areas with castor oil has been found to improve blood flow, which stimulates oxygen and nutrient exchange and promotes the regeneration of healthy skin tissue.
To maximize the benefits of castor oil for scar tissue, it's advisable to use a heating pad after applying the oil to enhance its absorption into the skin.
5. Promotes scalp health
Castor oil is one of the best natural remedies to manage a dry scalp and improve dandruff.
Due to the hydrating and moisturizing properties of ricinoleic acid, castor oil offers a deep conditioning treatment that helps nourish the scalp, lock in moisture, and reduce flakiness.
This can alleviate itching and irritation associated with dandruff, help prevent a dry scalp, and promote healthy hair follicle function.
6. Stimulates hair growth
A study published in Pharmaceuticals found that castor oil promotes hair growth and may benefit individuals with alopecia or other forms of hair loss.
The study highlighted the effectiveness of castor oil in enhancing scalp health and stimulating hair follicles, leading to increased hair density and reduced hair shedding.
Castor oil application can help strengthen hair strands, improve scalp circulation, and provide essential nutrients, making it a valuable natural remedy for those seeking to improve hair growth.
If applied regularly, castor oil's hair-growth-promoting effects may also help thicken and lengthen eyebrows and eyelashes.
How to use castor oil for healthy skin and hair
Whether used to improve scalp health, promote hair growth, or counter signs of aging, castor oil is a versatile skincare product that helps maintain radiant skin and healthy hair.
Castor oil is generally well-tolerated, including individuals with sensitive skin, and has been considered safe and effective by the Food and Drug Administration (FDA).
However, it’s crucial to perform a patch test to check for a potential allergic reaction or sensitivity to castor oil. If no symptoms develop within 24 hours of application, you can safely incorporate castor oil into your beauty routine.
Here’s how to use castor oil to promote healthy skin and hair.
Castor oil for skin care
To apply castor oil as a moisturizer, massage a few drops into clean skin, leave it on your skin overnight, and rinse off in the morning.
Castor oil has a thick consistency and can be diluted with another carrier oil, such as almond oil, coconut oil, or olive oil. This also helps mask the somewhat pungent smell of castor oil, which some people find unpleasant.
Putting castor oil on lips is an excellent way to keep them hydrated and protected as it locks in moisture, helping prevent dryness and chapping.
To manage microbial skin infections, apply castor oil to a cotton ball and gently dab it onto the affected area. Cover with gauze or a bandage to prevent the oil from rubbing off, and apply castor oil twice daily until the infection improves.
Castor oil for hair care
To use castor oil for hair care, apply it directly to the scalp and gently massage it into the skin to promote circulation and allow the oil to penetrate deeply. Leave it on for at least 30 minutes or overnight, then shampoo thoroughly to remove the oil.
Applying small amounts of castor oil to clean wet hair can help manage frizz and provide natural conditioning. However, castor oil isn’t recommended for individuals with oily hair as it may exacerbate greasiness.
You can apply castor oil to your eyebrows and eyelash line with a cotton bud or small brush to nourish hair follicles and promote hair growth. However, take care not to get the oil into your eyes, as this can cause irritation.
How to pick the best castor oil
Castor oil has become a popular skincare product and is readily available in pharmacies, health stores, and online retailers.
However, choosing a high-quality product is crucial to ensure purity and effectiveness.
Opt for cold-pressed or cold-processed castor oil, as this helps retain more nutrients and beneficial compounds compared to heat-processed oils. In addition, it’s important to choose hexane-free castor oil to minimize exposure to this potentially harmful chemical solvent.
Organic Jamaican black castor oil is generally widely regarded as one of the best products due to its rich nutrient profile, which is believed to enhance its effectiveness for skin and hair health.
Key takeaways
There are many castor oil benefits for skin and hair health due to its high concentration of ricinoleic acid, a moisturizing and anti-inflammatory fatty acid that can penetrate deep into the skin.
Regularly using castor oil can help moisturize and soothe dry and irritated skin, manage microbial skin infections, promote hair growth, and strengthen hair follicles.
