How to Grow Longer & Thicker Hair with Jamaican Black Castor Oil

Jamaican black castor oil is one of my best hair loss recovery recommendations in The Ultimate Hair Growth Guide.

In the earlier article on  How to Grow Thick Hair with Castor Oil, I discussed the benefits of castor oil, how to use it on your hair, and the best brands of castor oil for hair.

While clear castor oil is very effective, there are some people who believe Jamaican black castor oil works better. In this article, I’ll be breaking down:-

  • Jamaican black castor oil
  • Benefits of Jamaican black castor oil for hair
  • How to use Jamaican black castor oil for hair growth
  • Best Jamaican black castor oil brands for hair

What is Jamaican Black Castor Oil?

Jamaican black castor oil is a version of castor oil that has been processed in a different way. In this case, the castor seeds are roasted then ground.

Afterward, the castor beans are boiled and the oil is distilled from the beans.

Jamaican black castor oil is a deep dark brown with an accompanying toasty burnt smell, which isn’t unpleasant. Some people say it also smells like cigarettes. 

Jamaican black castor oil is a thick and viscous consistency just like the clear version.

Jamaican black castor oil has a reputation of being an “all-purpose” oil but this article will focus on the benefits for hair only.

Traditionally, Jamaican black castor oil was used for all kinds of ailments from skin care issues to internal problems.

Jamaican black castor oil is also enriched with vitamin E and Omega-6 fatty acids.

Does Jamaican Black Castor Oil Grow Hair?

While there are no scientific studies that prove Jamaican black castor oil grows hair, I think the proof is in the thousands of reviews about results online.

These reviews include my very real results as well which I share in Regrow Bald Spots with Jamaican Black Castor Oil.

I combined scalp massages with Jamaican black castor oil with several other methods to achieve these results, which I documented over 6 months. 

Jamaican Black Castor Oil Benefits

JBCO and castor oil have similar benefits but they may be amplified in JBCO.

Read What Are the Differences Between Castor Oil and Jamaican Black Castor Oil?

1. Jamaican Black Castor Oil is Raw and Natural

Jamaican black castor oil is raw and natural making it a potent treatment for hair conditions such as bald spots, thin hair, dandruff, and shedding.  

It doesn’t contain any harmful additives and hasn’t been adulterated with mineral oil or liquid paraffin. 

2. Jamaican Black Castor Oil Has Antifungal and Anti-inflammatory properties

According to this 2012 study, Jamaican black castor oil contains antifungal, anti-inflammatory, and antimicrobial properties.

These properties make Jamaican black castor oil an effective treatment for scalp conditions like eczema, itchiness, and flakiness. 

3. Hair Loss Recovery with Jamaican Black Castor Oil

One of the best advantages of Jamaican black castor oil is its ability to help treat hair loss, regrow bald spots, and trigger new growth.

When massaged into the scalp regularly, it nourishes the hair follicles and draws nutrients that encourage new growth in the scalp area. 

4. Jamaican Black Castor Oil Softens Hair

The vitamin E content in Jamaican black castor oil helps soften hair.

When mixed with your styling aid before putting in braid outs, twist outs, and finishing off a wash and go. It’s one of the primary oils in my hair growth oil.

5. Locks in Moisture 

Jamaican black castor oil’s thick consistency makes it a suitable oil for locking in moisture and is perfect for high porosity hair. 

It’s also a potent oil to use for the oil in the LCO (liquid, cream, oil) method.

6. Strengthens Hair & Reduces Breakage

Jamaican black castor oil contains high amounts of omega-6 and omega-9 fatty acids that can nourish dry and damaged hair.

It can also help strengthen weak hair strands and reduce hair breakage significantly. Additionally, it can protect the hair from split ends. 

How to Use Jamaican Black Castor Oil for Hair Growth

Jamaican black castor oil can be used in the same way outlined in the earlier article on castor oil.

In that article, I share 3 DIY castor oil recipes for hair growth, soft hair, and frizzy hair. You should experience the same if not better results. 

For more information on using Jamaican black castor oil for hair growth and pre and post hair loss pictures, read Regrow Bald Spots with Jamaican Black Castor Oil.


Castor Oil vs Jamaican Black Castor Oil

Several users of castor oil and Jamaican black castor oil have stated the JBCO is more potent than the clear castor oil because of the ash content.

However, this is a matter of opinion and experience. Some people find JBCO more effective while some people find the clear version more effective.

Personally, both worked for me but I preferred JBCO because I like the smell.

I recommend trying each separately for a few weeks and then judge for yourself. What works for one person’s hair won’t necessarily work on yours.

Where to Buy Jamaican Black Castor Oil?

Some suppliers have been known to buy the clear castor oil, darken it artificially or mix in a few drops of the real thing and pass it off as real JBCO.

Authentic Jamaican black castor oil always has the toasty burnt smell, which is produced due to roasting the beans.

The best and most recommended brand of Jamaican black castor oil is Tropic Isle Living Jamaican Black Castor Oil and Sunny Isle Jamaican Black Castor Oil

Jamaican Black Castor Oil Side Effects

Jamaican black castor oil is an all-natural product produced via natural methods and shouldn’t have any major side effects.

However, like all products, everyone’s hair and skin react directly to JBCO and there have been reports of skin irritation so it doesn’t hurt to do a patch test if you’ve never used JBCO before. 

Do not consume Jamaican black castor oil.

Jamaican Black Castor Oil FAQs

How Long Does Jamaican Black Castor Oil Take To Grow Hair? 

This depends on a lot of issues such as your diet, frequency of treatments, current hair issues, etc. 

If everything is as it should be and you follow usage instructions, you should start to see growth results from Jamaican black castor oil within 8 – 12 weeks. 

Complete turnaround and significant results should take about 6 – 8 months. Just be patient and consistent.

Can You Use Jamaican Black Castor Oil On Your Hair Every Day?

Yes, you can use Jamaican black castor oil on your hair every day. However, it should be diluted with other oils that are not quite as thick. 

Grapeseed oil, sweet almond oil, and olive oil are good oils for diluting Jamaican Black Castor Oil.

When Does Jamaican Black Castor Oil Expire?

Jamaican black castor oil has a very long shelf life and can last anything from one to five years based on production dates and storage methods.

Follow the manufacturer’s instructions and keep the oil in an airtight container away from sunlight.

Why Does Jamaican Black Castor Oil Cause Itchy Scalp?

Jamaican black castor oil is usually well tolerated. However, if it causes an itchy scalp then you may be allergic to the roasted beans but don’t despair.

You can try clear castor oil instead and if it’s still a problem, there are other hair growth oils you can try. Check out the hair loss archives for more on this.

Is Jamaican Black Castor Oil Good for Low Porosity Hair?

Jamaican Black Castor Oil is too heavy for low porosity hair.

For low porosity hair, you want a light and quickly absorbed oil like grapeseed oil, sweet almond oil, and jojoba oil. 

If you’re not sure what your hair’s porosity is, try one of the methods recommended in Hair Porosity Test.
