For quite some time people living all over the Caribbean have been enjoying the benefits of Jamaican black castor oil for hair growth.

Lately, it’s catching on in other parts of the world.

As a barber, I have only recently been made aware of what it can do so I assume there are plenty of you out there that want to know more about it.

In this guide, I will go over all the benefits you’ll see for your hair and scalp, which may even include regrowing hair.

It doesn’t matter if your hair is long, short, curly or straight, whatever the problem is, you’re sure to see some improvements after using castor oil for hair regrowth!

Before we go over the benefits, let’s talk about what it is.

What is Jamaican black castor oil?

Castor oil is pressed from castor plant seeds and was commonly used as a laxative for centuries as well as an ingredient in many cosmetics.

Usually, it is a straw colored, and thick oil.

In the case of Jamaican black castor oil, it has the addition of the ashes of the husks of the seeds. This gives it the dark color and also changes how it works to some degree. More on that in a minute.

Jamaican Black Castor Oil Vs. Castor Oil

Clear, or pure castor oil is cold pressed much like olives are for extra virgin olive oil. This retains many of the nutrients and fatty acids that benefit the hair and scalp.

To make Jamaican black castor oil, the seeds are roasted first and then crushed to extract the oil.

Though they use heat, the nutrients are still intact as it isn’t the heat from roasting before they are pressed that is the problem. When using heat or, worse, chemicals during the extraction process, the oil is altered. Roasting before they are crushed does not result in a loss of the benefits.

What does change is the pH level. The black castor oil is highly alkaline with the addition of the ashes.

Depending on what your scalp and hair issues are, this will treat your problems differently.

For instance, if you need a clarifying shampoo for acne or excess sebum production, then the black castor oil will work in place of that to the same effect.

Benefits of Jamaican Black Castor Oil

To understand the benefits, it helps to know what the properties are in black castor oil.

Castor oil in general is loaded with Omega 9, and Omega 6 fatty acids.

These fatty acids have benefits topically as well as when they are ingested. So using an oil on your hair and scalp that has these fatty acids has a lot of positives.

Then there is ricinoleic acid, which is another fatty acid that acts as an antibacterial, antifungal and anti inflammatory agent. When it come to natural hair regrowth, this acid is essential.

Here are the ways that black castor oil will help your hair:

1-Helps Treat Acne

The combination of fatty acids and the high alkalinity will wipe out any bacteria on your scalp. Then keep it away by creating an inhospitable environment for bacteria.

The castor oil penetrates the skin and repairs the dead skin cells so that they don’t end up attracting more bacteria later.

Since the black castor oil does have a high alkalinity, it can dry the skin out. If you have acne on your scalp, it probably means your skin is not dry, in fact quite the opposite. So this probably is not going to be an issue for most people.

2-Helps Treat Infections

A major cause of hair loss in people that don’t have male pattern baldness or genetics, is a skin infection.

Conditions like ringworm, folliculitis, seborrheic dermatitis and other infections can be treated to great effect with castor oil.

Castor oil is antibacterial, and antifungal.

After it kills the infection, it repairs the skin and improves circulation. This blood flow brings nutrients back into the scalp and then into the roots of the hair.

Once the infections are cleared up, your scalp is much less irritated and the hair should start growing back.

3-Moisturizes Hair

Packed with Vitamin E and the Omega 6 and 9 fatty acids, black castor oil does wonders for your hair hydration. Since castor oil is a natural humectant, it locks the moisture in your hair and keeps it looking fuller and shinier.

Adding castor oil to another carrier oil that also adds moisture is a good way to really take care of dry hair. I recommend an argan oil as that is one of the best oils for your hair and skin.

4-Improves Hair Strength

Having stronger hair means that it is less likely to fall out. If you see too much hair in your shower drain every morning, then you need to start by strengthening your hair.

Castor oil improves circulation in the scalp that brings nutrients and oxygen into the root of the hair follicle. This alone will make the hair stronger.

In addition, though, the castor oil also helps the hair during the keratinization process when it is in the growth phase.

Keratin is the building block of your hair and nails. High keratin means stronger hair.

5-Prevents Hair Breakage

Part of preventing hair breakage is creating stronger hair by using castor oil.

But what it also does is smooth out the cuticle in the hair which keeps the hair from breaking. It also makes it smoother and keeps dead ends from forming.

If your hair is brittle then the additional hydration, the extra keratin, and the improved circulation all contribute to hair that won’t break on you and look frizzy.

6-Leaves Hair Thicker

When your hair is hydrated and retains its moisture, it ends up thicker. If you use the castor oil during the growth phase, then the base of the follicle will actually end up thicker.

But, even if you get the castor oil treatment into your hair when it isn’t during that phase, it will still appear to be thicker.

If you have thin or wispy hair, then you can benefit from seeing less of your scalp shining through if your hair is thicker looking.

7-Helps Regrow Hair from Scalp Damage

I want to reiterate in case I didn’t make myself clear. Your hair won’t regrow by using black castor oil if your hair loss is genetic or from male pattern baldness.

You will see better looking hair that may hide some of your baldness by thickening your hair, but you won’t regrow it.

If you have a damaged scalp from skin conditions like I listed before then once your scalp is healed, your hair will grow back to some degree.

Unfortunately, if you lost hair in clumps, then you may still see some spots that don’t end up with growth.

It may take a month or two to regrow in those spots, but you will see some regrowth and your hair loss in those areas should stop.

How often should I use castor oil for hair growth?

This depends on how it feels when you first use it, but a general rule of thumb is no more than twice a week. Remember that the alkalinity may end up causing your scalp to be dry and can cause irritation even though the ricinoleic acid helps calm inflamed skin.

If the first time you use it, it feels uncomfortable, then you may need to go easy on it and use it only a couple of times per month. If it feels fine and you feel like you can use it more often then you can go up to twice per week.

What to keep in mind when using castor oil for hair regrowth

When you apply it, leave it in your hair for up to an hour. This will allow it to properly absorb into the hair. As it is thick, it needs that time.

Also, if your hair is blond or light brown, be prepared to have your hair looking much darker. This may be a desired effect, but you may not be looking to draw attention to the fact that you are trying to regrow your hair. Not that you should be embarrassed, but this is something guys can be sensitive about.

Pro Tip: Make sure you use over your shoulders when you apply and don’t sleep with black castor oil in your hair. It stains clothes very easily so make sure you wash it out well!
