Most of us are familiar with castor oil. It is a translucent liquid with a yellow tint and is widely found in various household items, from cleaning products to paint. It is also used to treat a wide range of medical conditions including digestive issues and various forms of skin and hair disorders such as alopecia. (1) There are not many studies or evidences available to prove the effectiveness of castor oil for skin and hair health. However, it has been used as an active ingredient in traditional medicines for centuries. The African and Asian countries believe that castor oil is an elixir for people who are longing for smooth, shiny, and voluminous hair.

In the past few years, Jamaican black castor oil has gained a tremendous amount of popularity. Instead of selling the conventional translucent castor oil, a lot of companies have now started selling the best black castor oil for hair growth. Wondering how the Jamaican black castor oil is different from the conventional castor oil? Don’t worry; in this blog we will cover everything that you need to know about the best brand of the Jamaican black castor oil and how it is better than the conventional castor oil for hair growth.

What is Jamaican black castor oil?

Both castor oil and Jamaican black castor oil are extracted from the seeds of castor oil plant. Both of them are quite heavy in feel and texture and are rich in vitamin C and fatty acids. They have anti-inflammatory, anti-fungal, and anti-bacterial properties, which is why castor oil is widely used in traditional medicine. The main difference between castor oil and the Jamaican black castor oil is the method of processing.

Castor oil is processed commercially by pressing the fresh castor beans. The beans are not heated and, therefore, it is very often marketed as cold pressed castor oil. The best black castor oil, however, is extracted in a very different way. The castor beans are first roasted and then pulverized in a mortar. The mashed beans are then mixed with water and slow-boiled on wood fire until you get a thick, pungent, dark brown oil, which is known as the Jamaican black castor oil. Although this oil has undergone heat treatment, it is still considered to be pure and much superior to the cold-pressed one, especially for hair treatment. The roasting of the beans adds a lot of ash content to the oil, which gives it a typical burnt smell and dark color. Hair experts believe that it is this ash content, which makes it more effective than its conventional variety.

The manufacturer claims that this best Jamaican black castor oil can also be used for moisturizing the skin, adding luster and shine to nails, and softening and removing calluses from dried, chapped feet. There are a lot of Jamaican black castor oil hair growth pictures from users that prove the claims of the manufacturer, which is why we are recommending this product. However, we strongly suggest that you must personally read the product description and check out the Jamaican black castor oil before and after pictures before placing your order.

  • Promotes hair growth: The omega- 9 fatty acids, also known as ricinoleic acid, present in the best Jamaican black castor oil is said to improve blood circulation to the scalp, thereby promoting hair growth. Ricinoleic acid is highly recommended for treating hair fall and even alopecia.

How to use Jamaican black castor oil

Using black castor oil is as easy as using any other hair oil including almond oil and coconut oil. All you need to do is to massage a few drops of it on your scalp and leave it overnight or at least for 2 hours. As mentioned above, the best Jamaican castor oil is too heavy and greasy. So, washing it off can be really difficult. You may have to apply shampoo twice or even thrice to get rid of the greasiness. If you do not want to use excessive amount of shampoo, you can dilute it with some other hair oils such as coconut oil or almond oil. There is no such ideal dilution ratio but experts recommend that you should make one part of castor oil with 5 parts of other hair oils. If you are using diluted best Jamaican black castor oil for hair growth, you can apply it on the scalp, into your hair’s midsection, as well as on the tips.

Important tip: Even the best brand of Jamaican black castor oil can stain your clothes. So, make sure you cover your head with a shower cap and wear old clothes while applying it.

Since it is very thick and greasy, even the best black castor oil for hair growth is not meant to be applied daily. If you are using it neat, you should apply it no more than once a week. If you are diluting it, still make sure you use it only twice or thrice a week and not more than that. Excessive use of castor oil can cause buildup and matting, a condition in which the hair get entangled to form a thick mass. This matted part cannot be treated and needs to be cut off. (2)

If you want to use black castor oil for filling in the bare patches of your eyebrows or to make your eyelashes grow longer, mix one part of castor oil with 5 parts of almond oil and apply it on the desired area with the help of a mascara brush or cotton swab. You can also use this mixture for growing your beard.

Precautions and side effects of best Jamaican castor oil

Castor oil is generally safe for all forms of external applications. There are a lot of manufacturers that sell black castor oil pills for hair growth but we do not recommend them, as an overdose of castor oil can lead to severe side effects such as nausea, abdominal cramps, etc. We strongly recommend that you must use Jamaica black castor oil externally. However, feel free to do a patch test to see if your skin is allergic to it. Mild allergic reactions are noticed in rare cases. Yet, it is worth doing a patch test. All you need to do is to rub a few drops of best Jamaican black castor oil for hair growth on your feet or your forearm and leave it for 24 hours. If you witness swelling, itching, redness, rashes, or burning sensation, you are probably allergic to it. In such a case, you must not use it. If the allergic reaction persists for 2 days, consult a doctor.

As mentioned above, even the best Jamaican black castor oil is very heavy and greasy and, therefore, you must be very careful to wash it off completely. If you fail to wash it off, it can attract dust and dirt, thereby making your hair dirty and filthy. Moreover, if left, castor oil can cause matting i.e. your hair can get entangled severely. Such a mass of hair cannot be detangled and you will have to cut it out.

Bottom line

Jamaican black castor oil is an effective and economical solution for boosting hair growth and improving the quality of your strands. It is very easy to use and widely available on Amazon and other online websites. However, if you are suffering from excessive hair loss, it could be a sign of an underlying disease. Please consult your doctor for a thorough evaluation.
