Coconut oil and Jamaican black castor oil are two of the most popular natural hair oils, and mixing them is a common trick. The idea is simple: coconut oil is light and spreads easily, while Jamaican black castor oil (JBCO) is thick and heavy. Blend them and you get something easier to apply that still seals in moisture. Here is how to do it properly and what to expect.
Why Mix Coconut Oil and Jamaican Black Castor Oil?
JBCO is made from roasted castor beans, and the ash from roasting gives it a dark colour and a stronger, smoky smell. It is very viscous, which makes it hard to spread through thick hair. Coconut oil is thinner and, according to research, can penetrate the hair shaft and reduce protein loss. Combining them gives you spreadability plus sealing power.
JBCO vs Regular Castor Oil
Regular (yellow) castor oil is cold-pressed from unroasted beans. JBCO is roasted, and the ash makes it slightly more alkaline. Many people with coily or textured hair prefer it, though there is no proof it grows hair faster. For a full overview of the plain version, read our guide to castor oil for hair.
Best Ratio for Coconut Oil and Jamaican Black Castor Oil
- 1 part JBCO to 2 parts coconut oil: light and easy, good for fine or low-density hair.
- 1 to 1: balanced, the most popular starting point.
- 2 parts JBCO to 1 part coconut oil: thick and sealing, for coarse or very dry hair.
Warm the coconut oil until it is liquid, stir in the JBCO and store in a clean glass jar.
How to Apply the Mix to Your Scalp and Hair
- Start with clean, slightly damp hair so the oil seals in moisture.
- Section your hair and use a few drops on your fingertips for the scalp.
- Massage for two to three minutes. The massage boosts circulation, which is the more likely reason people see healthier hair.
- Smooth the leftover oil down the lengths and ends.
- Leave for 30 minutes to overnight, then wash with shampoo.
What Results Can You Realistically Expect?
Expect softer, shinier hair and less breakage. Do not expect miracles on growth. Hair grows about half an inch a month, and an oil can only help you keep the length you already grow. If you are comparing other options, take a look at jojoba oil, which is lighter and suits fine hair better.
Who Should Skip This Combination?
Coconut oil is not for everyone. Some people find it makes their hair stiff or brittle, especially if it is low porosity or protein-sensitive. Coconut oil can also be comedogenic on the skin, so avoid getting heavy amounts on the forehead. If your scalp is oily or dandruff-prone, test a small area first. People with a castor allergy should also stay away, and JBCO should never be swallowed.
Common Mistakes
- Using too much, which leaves hair greasy and attracts buildup.
- Applying to a dirty scalp, which traps debris.
- Skipping the patch test.
- Expecting overnight results.
