The benefits of castor oil are well-recorded in the beauty world. The best castor oil for hair care is a remedy that helps with hair fall, breakage, and dandruff issues. In fact, you can even apply it to other spots, such as your eyebrows and eyelashes, to promote growth. According to Board-certified dermatologist Dr. Lucy Chen, MD, FAAD, “Although castor oil doesn’t necessarily promote hair growth, it provides some benefits for your hair. This hair care staple is often used as a conditioning agent that can improve the flexibility of hair fibers and fight off bacterial overgrowth on the scalp that could potentially damage the hair.”

Before buying castor oil for topical use, ensure it is authentic and does not contain any additives. Many brands may add preservatives to increase the shelf-life of the product. However, such additives may often cause allergic reactions. If you have a sensitive scalp and skin, look for products that are clinically verified and dermatologically tested that are safe for your skin type. You can also seek consultation from a healthcare professional for better guidance on the use and frequency. Here are a few pointers to keep in mind before purchasing castor oil.

What Is Castor Oil?

Castor oil is extracted from the seeds of the Ricinus communis plant. It is a colorless to pale yellow vegetable oil with a sharp taste and odor. Castor oil contains ricinoleic acid (a primary fatty acid) and is used for medicinal, industrial, cosmetic, and pharmaceutical purposes. It is said to have anti-inflammatory, antifungal, wound healing, and antimicrobial properties.

Castor oil is preferred by many for promoting hair growth and maintaining its health. If you want to include it in your hair care routine, check out the listed products.

Things To Consider Before Buying Authentic Castor Oil

  •  Purity

Pure castor oil is free of artificial ingredients, chemical compounds, and harmful toxins. It shouldn’t contain artificial ingredients, such as fragrances, alcohol, or other flavorings, as these ingredients may dry out or irritate your skin.

  •  Certified Label

Look for products with the USDA or ECOCERT Certified label. Organic castor oil uses natural ingredients and castor seeds grown without pesticides, fertilizers, or growth enhancers.

  •  Authorized Seller

Always purchase from authorized sellers. Look for the product in pharmacies, branded stores, and healthcare stores. If you are purchasing it online, make sure that you buy it from reputable e-commerce store or the official website.

  •  Grade

Castor oil comes in two grades, and you can choose one based on your preferences:

a. AA Standard or “Pale Pressed”: This type of castor oil is prepared from the first pressing of the seed, also known as ‘virgin oil.’ It is diluted and light.

b. Imported: It refers to mixing the first batch of seed pressing with the next batch of seeds. It is a continuous process, prepared multiple times.

  •  Hexane-Free

Hexane is a solvent used to extract oil from the seeds. Using hexane for oil extraction often increases the risk of impurities and may affect the oil quality. Therefore, avoid buying castor oils that contain hexane. Other than these factors, you should also check the type of castor oil you are buying.

  • Additional Uses

It is better to opt for a multi-purpose oil (can be used on skin and brows), this will allow you to reap all the benefits and be light on the pocket too.

Types Of Castor Oil

There are three types of castor oils:

  •  Organic/Cold-Pressed Castor Oil: Organic/cold-pressed castor oil is extracted directly from the castor seeds without heating.
  •  Jamaican Black Castor Oil (JBCO): Jamaican black castor oil is prepared by roasting and crushing the castor seeds in a mortar and slow-boiling the seeds with water.
  •  Hydrogenated Castor Oil (Castor Wax): It is produced by the hydrogenation (a chemical reaction process in the presence of a catalyst) of pure castor oil, often in a nickel catalyst.

Pure castor oil is mostly viscous and may take time to get absorbed into the skin. Here are some tips on how you can apply castor oil to your hair, eyebrows, and eyelashes.

How To Apply Castor Oil The Right Way

For The Hair

  • Cover your shoulders with a microfiber hair towel.
  •  Pour some oil in your palm.
  •  Massage your scalp with it for 3-4 minutes.
  •  Apply the oil to the rest of your hair.
  •  Let it sit for at least an hour.
  •  Wash out the oil.

For The Eyebrows

  •  Clean your eyebrows and remove any traces of makeup.
  •  Apply castor oil to your eyebrows with a cotton swab or a clean mascara wand. Ensure it does not get into your eyes. If it does, wash it out immediately.
  •  Leave it on overnight.
  •  Wash it off the next morning with a mild cleanser.

For The Eyelashes

  •  Clean your eyelashes and remove any traces of makeup.
  •  Apply castor oil to your eyelashes with a Q-tip or a mascara wand (just like you apply mascara).
  •  Leave it on overnight.
  •  Remove the castor oil with water or makeup remover.

While castor oil is a widely used remedy for hair growth and people have found it quite useful after incorporating it in their hair care routine, there is no substantial evidence to prove this claim. Hair care experts also suggest using castor oil for hair growth.

Is Castor Oil Beneficial For Hair Growth?

Dr. Chen says, “No, castor oil does not promote hair growth. There has yet to be substantial clinical evidence to say that castor oil accelerates hair growth. Due to its polarization, it’s commonly seen as a gentle method of cleansing the skin, but there is no sufficient evidence claiming it can increase hair growth. In addition, some people can be allergic to it and experience inflammation, which could do more harm than good.”

The Bottom Line

Castor oil is one of the most beneficial products for hair thickness and growth. Since this oil can be beneficial in repairing dry and damaged hair as well, castor oil can carefully increase the hair density in your eyebrows and eyelashes. The sticky texture of castor oil is known to provide maximum nourishment to each hair strand in your brows. With the help of castor oil, you can hydrate and nourish your hair for a good glow. You can even use it as a natural hair mask ingredient to provide maximum nutrition and strength to your tresses. For multipurpose use, try Seven Minerals’ Jamaican Black Castor Oil with added aromatherapy and relaxation effects. For conditions like dandruff and dry scalp, opt for the Kate Blanc Cosmetics Castor Oil, and try the Home Health Castor Oil for all your DIY remedies.
