    When it comes to carrier oils and hair care, castor oil always seems to get left out. Black castor oil gets mentioned every once in awhile, but no one seems to care to explain the difference between black castor and “regular” castor oil.

    The rise of castor oil hair “remedies” on social media, seems to only confuse the matter further. No, castor oil doesn’t “instantly make your hair grow.” Yes, castor oil is all-natural. No, black castor oil and unrefined castor oil are not “basically the same thing.” Yes, both castor oil and black castor oil can help your hair look and feel healthier.

    We’re here to lift the veil surrounding castor oil and give it to you straight. We’ll cover castor oil hair benefits, simple DIY castor oil recipes you can use for more #goodhairdays, and how to use it for your brows and lashes. We’ll also break down the difference between castor oil and black castor oil and explain how to use castor oil to balance pH levels of your hair and scalp.

    Castor Oil vs. Black Castor Oil

    Castor oil and black castor oil are both natural products made from the seeds of the Ricinus communis plant, or castor oil plant. The castor oil plant produces spiny fruits that contain seeds which are sometimes (mistakenly) called castor beans. Removing the seeds from the hull of the castor oil fruit is the first step in castor oil production. From there, the tale of the two oils diverge.

    What is Castor Oil?

    Regular, or unrefined castor oil is a simple tale. Intense pressure is applied to raw castor oil plant seeds until the oil squishes out. The mashed seeds are filtered out of the oil and the resulting product is unrefined castor oil. This way of making castor oil is called the cold-pressed method due to the pressing of the seeds and the lack of heat used during that processing.

    Unrefined castor oil is pale yellow and thick with a very mild aroma. Using unrefined castor oil for skin care is more common in practice, although there are also several benefits to using it for hair as well. Both types of castor oil contain high amounts of ricinoleic acid which can help soothe the scalp and hydrate hair. Cold pressed castor oil also has a low pH level, meaning it is more acidic (more on that later).

    What is Black Castor Oil

    Instead of using raw castor oil seeds, roasted castor oil seeds are vital to the production of black castor oil (also known as Jamaican black castor oil). The roasted castor oil seeds are then crushed, boiled and pressed to extract the oil. The seed pulp is removed from the oil and then castor oil seed ashes left over from the roasting process are added back in.

    The ashes are what gives black castor oil its distinctive color, smell and specific hair care benefits. Black castor oil is a slightly thinner in consistency than unrefined castor oil, can be anywhere from dark gray to black in color, and has a distinctly smokey smell. The pH level of black castor oil is high, which means it’s more alkaline. The alkaline nature of black castor oil means it can be used to balance highly acidic hair.

    Balancing pH Levels with Castor Oil

    The pH levels of your hair and the pH levels of the oils should be the number one consideration when deciding between regular or black castor oil for hair care.

    Cold pressed castor oil has a low pH level (more acidic) and black castor oil has a high pH level (less acidic and more alkaline). What does that mean? Well, you’ve probably heard the phrase “pH balanced hair” at the salon or in hair care commercials. That’s because human hair looks and feels the healthiest when it’s slightly acidic.

    To choose the right castor oil hair treatment for your hair, first you need to figure out the current pH level of your hair and scalp. Once you know your pH level you can apply a castor oil with the opposite pH level.

    How to Figure Out Your pH Levels

    One way to determine the pH level of your hair is to pay attention to how your hair and scalp feel. If you experience a flaky scalp that itches, it’s likely your hair has been stripped of its natural acidity. In this case, your hair has a high pH level, so unrefined castor oil with its low pH level would be the best option.

    Lower pH levels can also help reduce the friction between hair fibers and lead to less breakage and frizzing. Even if you don’t suffer from an itchy flaky scalp, unless your hair is naturally coarse, dry, or overly-processed, cold pressed castor oil is still most likely the best choice for your locks.

    Another way to determine the pH level of your hair is to consider your hair’s texture and processing history. Naturally curly, kinky, or coarse hair tends to have porous individual strands and is more likely to have a low pH level. Same goes for hair that is damaged from a ton of chemical processing like perming and bleaching.

    Porous hair is often very dry because it has a hard time retaining moisture. The open porous texture lets water in, but also lets it right back out again. The repetition of this process is called hygral fatigue which leads to hair damage and breakage. If your hair shows signs of a low pH level, the alkaline nature of black castor oil (high pH) can be used to restore balance so your hair stays moisturized.

    Other Castor Oil Hair Benefits

    High in Fatty Acids

    Castor oil is rich in ricinoleic fatty acids that are key in how castor oil works to condition your hair and scalp. Of all the natural carrier oils, castor oil is the only one that contains ricinoleic acid.

    Deeply Conditions Hair

    The ricinoleic acid (RA) in castor oil delivers moisture to your hair and helps “seal” it in by lightly coating your hair strands. Lightly coating your hair with castor oil helps support the structural integrity of the individual strands, which is key to helping your hair look shiny and healthy.

    Castor Oil is Humectant

    Moisturizers that are naturally humectant, like Castor oil, pull in water from the atmosphere and trap the moisture in place. The humectant properties of castor oil add to its moisturizing hair care power.

    Conditions & Cleanses Scalp

    The moisturizing properties of castor oil that are good for hair, are also good for conditioning your scalp too. On top of that, the anti-inflammatory properties of RA help soothe minor inflammation which can help calm irritated scalps. Castor oil also has antibacterial activity to help keep your scalp clean and fresh.

    Inexpensive DIY Hair Care

    Making your own natural hair care recipes at home is more affordable than you think. Castor oil is one of the least expensive and just a little goes a long way. Unrefined castor oil is super versatile and works really well as a base for adding essential oils to your hair care.

    How to Use Castor Oil for Eyebrows & Lashes

    Eyebrows are hair too! So are lashes, and they both deserve the same conditioning TLC as the hair on your head. Conditioning your lashes and brows with castor oil is ridiculously easy. All you need is a couple drops of castor oil, a clean unused toothbrush and a small clean bowl or dish.

    Instructions:

    Step 1: Add a few drops of castor oil to your bowl or dish.

    Step 2: Dip your clean brush in the castor oil.

    Step 4: Let sit overnight and wash your face in the morning. Repeat 1-2 times per week.

    The Takeaway

    Unrefined castor oil is an inexpensive, versatile carrier oil with several hair benefits. Rich in ricinoleic fatty acids, castor oil is a humectant moisturizer that deeply conditions both hair and scalp. Cold-pressed castor oil can also be used to condition your eyebrows and lashes, and for mixing with essential oils to make your own homemade natural hair products.

    Castor oil is also one of the best ingredients to balance the pH levels of your scalp and hair. Unrefined castor oil and black castor oil are two different types of natural vegetable oils that can be used expressly for balancing pH levels. For high pH levels use cold-pressed castor oil and for low pH levels use black castor oil.
