Best Castor Oil for Hair Growth & Thickness

Beauty oils are now incorporated into most hair and skin care regimens. Beauty oils are part of the modern era of the health and cosmetic world. They are deemed to have moisturising and antibacterial qualities that create a defensive barrier. Castor oil is amongst the most sought-after hair oils that has a long range of medicinal and commercial uses. It is famous as the oil that aids hair growth and its thickness. The oil is extracted from the seeds of the Ricinus communis plant. The seeds contain ricin, a potent toxin that is lethal when swallowed or inhaled in powder forms. The oil has been around since the Ancient Egyptians first used it as a laxative, and is now considered one of the world’s oldest herbal medicines.

In modern times, castor oil is found in many natural beauty products that claim to improve hair and skin texture, as well as promote hair growth and volume.

    What to know more before buying castor oil?

    When choosing the best castor oil in the market, one must consider a lot of factors, like the ingredients, how it is manufactured, certifications and reviews. But there are other things to know about castor before adding it to the beauty routine. There are instances that must be put into mind before starting to look for the appropriate castor oil, especially on how organic they claim to be. Some individuals experienced irritation when using the oil because some brands do not disclose the truth regarding how “pure” the product is. It is important to make thorough research regarding the brand and always be aware of the additional ingredients being put in. Castor oil is believed to relieve wounds and throat infections and is used as a laxative to alleviate infrequent constipation, but is not advisable for children and people with high levels of sensitivities. 

    For individuals that are looking into a more cost-effective and sustainable use, one might choose between castor oil that comes in a glass or plastic bottle. Glass bottles in dark amber colour are preferable since it is stable and not easy to produce a chemical reaction and provides a good barrier to prevent the oil from deteriorating over time. The strong rigidity of the glass bottle compared to the plastic ones is not easy to deform because of the heavyweight. A glass bottle is more convenient to disinfect compared to plastic bottles. Plastic bottles tend to release toxins if they are washed or heated. 

    What are the best ingredients in castor oil for hair growth?

    The main components of Castor oil are ricinoleic acid, oleic acid, palmitic acid, and Omega fatty acids. Ricinoleic acid makes up 90% of castor oil and is deemed to promote blood circulation in the scalp to promote hair growth whilst intensely moisturising it. Oleic acid stimulates the growth of longer and stronger hair. Omega fatty acids both promote hydration and the palmitic acid softens the strands without the oily residue.

    What are the ways to apply castor oil for hair?

    Castor oil is more than just applying it directly to the intended areas of concern. Knowing the proper ways to apply it gives off its benefits and surely produces satisfactory results. 

    Listed below are the ways how to apply castor oil for hair.

  • Warming the oil before using. Heating up the castor oil before the application guarantees faster absorption and helps in loosening up flakes and build-up, allowing hair follicles to breathe and grow healthily. 
  • Combining with other oils. Castor oil is mixed with lighter oils such as coconut oil, sunflower oil or olive oil. Since each of the oils has different properties and nourishing benefits, it would much likely give the hair an additional conditioning boost.
  • Leaving the oil overnight. The oil is absorbed more if left to sit on the scalp or hair for a longer period, then wash it off the next morning. This gives the hair the ultimate nourishment and shine. 
  • Using cold-pressed variants. Cold-pressed castor oils are much more beneficial and effective since the oil is extracted without heat, thus, retaining the vital nutrients and vitamins of the castor oil. The cold-pressed variant is the best for recovering damaged hair, by learning how to apply castor oil for the hair and when should it be applied.

  • What are the different types of castor oil?

    Castor oil is not only limited to one variant. With its popularity, a lot of varieties and formulations exist depending on where it is used.

    Listed below are the different types of castor oil.

  • Sulphated Castor Oil. Known as “Turkey red” castor oil has a wide array of uses, including, lotions, creams, shampoos and many more. It is the only type of castor oil that completely disseminates with water and does not leave an oily ring when incorporated into other cosmetic products. 
  • PEG 40 Hydrogenated Castor Oil. PEG 40 is used as a fragrance enhancer and foam booster. It naturally mixes with both oil and water, that’s why it is an excellent emulsifier. 
  • Black Castor Oil. The oil has a dark/burnt colouration due to roasting the seeds of the Ricinus communis plant before extracting. The oil has a nutty scent that differentiates it from other different types of castor oil. 
  • Yellow Castor Oil. It is intended for general use and is extracted by cold-pressing fresh castor beans.

  • Does Castor Oil Help With Hair Growth?

    Yes, castor oil helps with hair growth. Castor Oil is beneficial to the hair mainly because it contains components like proteins and omega fatty acids that enhance blood flow to the scalp, supporting hair growth. Protein aids in giving the hair the strength it needs to prevent hair fall. Omega Fatty Acids supply the hair with its needed proteins and nourishment. Additionally, Castor oil has ingredients that protect the scalp from undergoing stress, resulting in hair loss.
