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 oilhas 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?

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.

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.

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?

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

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.
