Jamaican black castor oil (JBCO) is obtained from the Ricinus communis plant seeds or Jamaican castor beans. The seeds are roasted and cold-pressed to obtain the black castor oil, which is rich in ricinoleic acid. This nourishing oil has been used in Jamaica since ancient times for hair growth and treating dandruff, itchy scalp, muscle pain, and acne (1).

protip_icon Did You Know?
The history of JBCO has roots in rural Jamaica. Ex-slaves produced the oil from castor seeds brought to the Caribbean from Africa during the slave trade between 1740 and 1810.

  2. Apply it to your hair strands.
  3. Leave it on overnight. Shampoo your hair the next day.
  4. Do this twice a week.

I am guessing that I’ve grown about an inch (i).”

2. Hot Oil Treatment

You Will Need

  • 20 drops of JBCO
  • Warm towel
  • Shower cap


  1. Warm the JBCO.

  3. Apply steam for 10 minutes. You can also wrap a warm towel around your head.
  4. Wear the shower cap and wait for 20 minutes.

Note: The oil should be warm to the touch, but not steaming or painful on your hand. If it is too hot, it will burn the cuticle instead of hydrating it.

JBCO, like regular castor oil, is quite thick, sticky, and vicious. You can dilute it with other hair and essential oils to prevent any stickiness.

You Will Need

  • 6 drops of almond oil


  1. Mix the JBCO with the lavender essential/peppermint oil and almond oil.
  2. Massage this oil blend onto your scalp and hair.
  3. Wait for 30 minutes before washing.

4. Add To Hair Masks

  • Yogurt


  1. Mix the JBCO with yogurt to form a smooth paste.
  2. Apply this paste to your hair for a dandruff-free scalp and soft and shiny hair.
  3. Wait for 30 minutes before washing your hair.
  4. Do this at least once a week.

Note: You can also add JBCO to the mashed avocado hair mask to revive dry, damaged hair.

Frequently Asked Questions

What happens if you use Jamaican black castor oil everyday?

Jamaican black castor oil is safe for everyday use. It is recommended to be applied daily if your hair is unmanageable, frizzy, and dry. However, if your hair is not severely damaged, you may use it 2-3 times a week to avoid buildup.

Can Jamaican castor oil cause baldness?

No. There is no scientific evidence suggesting that Jamaican castor oil can cause baldness or hair loss.

What are the side effects of Jamaican black castor oil?

Jamaican black castor oil could lead to health-related side effects like dizziness, nausea, low blood pressure, abdominal cramps, etc. See a doctor if you experience such symptoms after using the oil.

What is the difference between castor oil and Jamaican black castor oil?

The most obvious difference between your regular castor oil and the Jamaican black variant is the color. While castor oil is light yellow, Jamaican black could be dark brown or blackish. Castor oil is made by cold-pressing castor beans. Jamaican black is made by roasting the beans, grinding them into a thick paste, and then boiling in water where the oil is skimmed out as it rises to the surface. Castor oil is better in reducing frizz while Jamaican black opens up the hair cuticles for better absorption.
