Guide to Jamaican Black Castor Oil

Whether you’re new to JBCO or have used it before, you’ll find this guide useful. Here’s a complete rundown of what the oil is, what it does, and how to use it.

What is Jamaican Black Castor Oil?

Castor oil is a hair treatment dating back to ancient times. It’s used to protect, strengthen, and beautify all types of hair.

Jamaican black castor oil is a type of castor oil made from castor seeds. Its effects are similar to castor oil with a few key differences:

  • Many people think JBCO is stronger and more efficient
  • JBCO has a different color and smell than a traditional oil

Jamaican black castor oil originated in the Caribbean, where it’s a popular health and beauty product used for hundreds of years. Practically anyone with connections to the Caribbean is familiar with JBCO.

Increasingly, more and more Americans know about it, too. The market for Jamaican black castor oil here exceeds $28 million a year.

One last thing about JBCO uses. Yes, castor oil is a power laxative. However, if you want to use it for that purpose, first consult your doctor. Easier, more effective alternatives are usually available. 

What are the Benefits?

Alright, so you now know what it is, but what does it do? Well, JBCO does a ton of different things. It’s a true multi-use product. Here’s a closer look:

Hair Growth

The oil helps increase hair length and thickness. It also increases the speed of hair growth. Many people use it to counter thinning hair and conquer bald patches.

Additionally, it promotes thick, healthy eyelashes and eyebrows. Note that applying it to your eyelashes does requires special care to keep your eyes safe.

Along these same lines, many people use the oil to help tackle dandruff. It helps hydrate your scalp to prevent flakes from forming at the source.

Skin Health

Although it’s probably more popular as a hair treatment, Jamaican black castor oil is also widely used as a skin treatment.

The main ingredient in castor oil is ricinoleic acid. It’s an effective anti-inflammatory that helps reduce wrinkles, increase elasticity, reduce acne, increase hydration, and more.

Many people use castor oil to cleanse their face. It clears pores without drying skin. If you’ve ever heard someone use the phrase “oil dissolves oil” when describing a face wash, the person was probably talking about a type of castor oil.

Nail Health

It has two benefits to nails. First, it’s a powerful antifungal and antibacterial agent. Regular application helps promote strong, healthy nails. Also, the oil helps soothe and protect the skin around your nails.

Pain Relief

To be honest, I’ve never found concrete scientific evidence that JBCO helps treat or prevent pain. However, many people swear it does. They use it as a balm for any hurt or achy areas, especially joints. If it works for you, great, but pain relief isn’t a benefit I’ve personally experienced. 

How to Apply it to Your Hair

If you’re like me, you’re mainly interested in using the oil to help boost hair health and reduce hair loss. Fortunately, JBCO is versatile and easy to use. You can apply it to your hair in a wide variety of different ways.

Here’s a closer look at the most popular application methods:

Pre-Shampoo Treatment

Shampoo dries your hair. Considering many black men and women already deal with dry hair, frequent shampooing can only make the issue worse.

Jamaican black castor oil is often used as a pre-shampoo treatment. Apply it before shampooing to moisturize your scalp and hair. It also helps augment your shampoo’s anti-dandruff properties.

The key to effectiveness is regular use. Also, apply it thoroughly throughout your hair. Because JBCO is a thick liquid, many people prefer to mix it with a lighter type of vegetable oil.

Hydration Boost

Is your hair seriously damaged or dry? I’ve found success with a moisture-infusion treatment. My friend swears it’s from Jamaica, but all I know is that it works well when my hair needs hydration.

Here’s the recipe:

  • 1 tbsp Jamaican Black Castor Oil
  • 1 tbsp argan oil
  • 1 tsp of olive oil
  • 1 egg
  • 4 tbsp condition

Mix it all together. Then massage it into your hair down to your scalp. Yes, it’s gross, but it also works. Cover your hair with a hot towel. If you have a heating cap, put that on, too. Regardless, keep it on your head for about 20 minutes. Afterward, rinse your hair with warm water.

Overnight Treatment

Apply JBCO to your scalp before bed. Spend about five minutes massaging it thoroughly. You want it to cover the base of the hair follicles on the scalp. Wrap your head in a scarf or towel.

You’re ready for bed. Let the JBCO work its magic during the night. In the morning, rinse the oil from your hair.

Use overnight treatments about three times a week. You should see thicker, fuller hair in about two weeks. Generally, this treatment helps revitalize damaged hair. You don’t have to use overnight treatments three nights a week once your hair is hydrated and healthy. After all, that could seriously impact your social life!

Hot Oil Treatment

You’ll need a hot oil applicator bottle for this treatment. Fill it with equal parts of Jamaican Black Castor Oil and coconut oil.

Cap the bottle and shake it until the contents have mixed thoroughly. Place it in a pot of rapidly boiling water. After five minutes, remove carefully.  

Use the applicator bottle to apply the oil to your hair. Cover as much of your hair as possible from scalp to tip. Only apply it to clean, wet hair.

Leave the oil in your hair for about half an hour. For best results, cover your hair with a shower cap or loose towel.

Finally, rinse the product away with warm water. You don’t need to use shampoo, although it can help remove the oil. Perform this treatment once or even twice a week on dry or brittle hair until you notice improvement.  

What’s the Difference Between Castor Oil and Jamaican Black Castor Oil?

Different production methods produce different benefits.

It all starts with the castor bean. Bizarrely, the hull of the castor seed is used to make the deadly poison ricin. However, removing the hull and then pressing the seeds creates castor oil.

Castor Beans

The beans are cold-pressed, a process used to create oil without using heat. Because heat can alter the chemical composition of the bean, cold-pressed oils are often considered pure.

Jamaican black castor oil starts with the same castor beans but uses a different extraction method. The beans are roasted, ground, and then boiled. Unlike castor oil, which is yellow, Jamaican black castor oil is darker with a slightly-burnt odor.    

Both types of castor oil contains ricinoleic acid. As discussed earlier, ricinoleic acid is an omega fatty acid that helps moisturize, reduce inflammation, and stimulate follicle growth.

So, if they both contain the same main ingredient, what’s the difference between the two oils?

It’s the pH level. Cold-pressed extraction lowers the pH of the oil, making it acidic. However, Jamaican black castor oil has high pH levels, so it’s more alkaline.  

Alkaline products have anti-inflammatory properties. They treat issues such as acne, sunburn, fungal infections, and other skin blemishes. That’s one reason why some people prefer JBCO over traditional castor oil.

Another reason is that Jamaican black castor helps increase collagen production. Collagen helps increase skin fullness and elasticity, reducing signs of aging such as wrinkles.

Finally, many people consider JMCO a more pure form of castor oil. Although specifics vary, many people believe JMCO works faster than the traditional type when repairing damaged hair. While I’ve never tried traditional castor oil, Jamaican black castor oil has always worked quickly for me!

Is Jamaican Black Castor Oil Safe?

Generally, you shouldn’t have any problems. However, any new substance can pose a few risks.

The biggest potential worry with JBCO is an allergy. You might want to apply a small drop to your arm or wrist. Watch the area closely for about 30 minutes to an hour. If you don’t experience any redness, itching, or other irritation, then you probably don’t have an allergy to the oil.

Another potential problem is the risk of burn injuries. Many JBCO treatments involve the application of hot oil. Always wear gloves and take other precautions when creating any hot oil treatment. Also, make sure the treatment is suitably cool before applying to your head.

The 7 Best Brands of Jamaican Black Castor Oil

While all of the products have the same basic ingredient – Jamaican black castor oil – you’ll find important differences in quality and effectiveness based on manufacturing processes and other factors. Here’s a closer look at seven popular JBCO brands:

Shea Moisture Jamaican Black Castor Oil

Shea Moisture’s Jamaican black castor oil is especially effective at repairing damaged hair. It helps remove build-up from shampoo, soap, and other products.

It’s versatile, too. You can use it on practically any type of natural hair, including hair that is kinky, curly, or wavy. It also works well on hair that undergoes frequent styling procedures like coloring, straightening, perming, or heat-based applications.

The oil is formulated with two products of note. First, it includes certified-organic Shea Butter to help reduce breakage and promote growth. Also, it includes Peppermint Oil, which creates a satisfying tingle against your scalp.

On the downside, it’s probably not the best choice if your main goal is conquering dryness. Regular use can dry your hair out slightly, although that’s only a concern if your hair is already severely dry.
