Cold Pressed Castor Oil VS Jamaican Black Castor Oil

Now as we all know the benefits of Castor oil.
It can be used both Internally and External.
In this case I we are going to be using it externally in the hair department.
But first we have to see the two main difference in the Cold Pressed Castor Oil and the Jamaican Black Castor Oil .

1) Cold Pressed Castor Oil
Cold pressed oil is oil produced through a combination of grinding and low heat. Many types of fruits, seed , and vegetables can be used to make it, but not all cooking oils go through this process. The introduction of heat to the process of making most oils degrades their flavour nutritional value, and colour, and may expose them to toxins. (http://tinyurl.com/83afndu)

Dr Pheonix (via Curlynikki) writes: "Manufacturers will use different types of processing methods when extracting oils from plants. And an oil will be either unrefined or refined based on how it was extracted from a plant. Unrefined oils retain most if not all of their nutritive properties, while refined oils will lose some (or possibly all) of their nutritive properties. 

Cold-pressed castor oil, is a colourless to very pale yellow liquid with mild or no odour or taste. It is a triglyceride in which approximately 90% of fatty acid chains are ricinoleic acid (interestingly, castor oil is the only place where this acid is found). Oleic and linoleic acids (essential fatty acids) are the other significant components of castor oil. A good reason to use cold-pressed castor oil instead of refined castor oil is that cold-pressed oils retain much more of these valuable nutrients. (http://tinyurl.com/bzw2omu)

2) Jamaican Black Castor Oil

Sunny Isle Jamaican Black Castor Oil is processed the “old fashioned “Jamaican way. Our Organic seeds are roasted and grounded by a manual grinder, after which the beans are boiled to extract the 100% pure, dark brown organic oil. Sunny Isle Jamaican Black Castor Oil is the best quality oil on the market. Why you may ask? Over the last ten years it is an established precedent that Jamaican Black Castor Oil is more effective than the clear Pharmacy Castor Oil because of the Ash Content in Jamaican Black Castor Oil due to roasting of the beans. Therefore it stands to reason that the more Ash Content the more effective the Oil. This is not a myth, it is evidence based FACTS. Compared to other brands, it is the darkest Jamaican Black Castor Oil because we roast our beans longer, which produces more Ash Content in Sunny Isle Jamaican Black Castor Oil than any other oil on the market. More Ash content increases the effectiveness and the colour of the oil. Therefore, the Sunny Isle brand will strengthen and increases hair growth faster than any other brands on the market today. Sunny Isle Jamaican Black Castor Oil comes in a safety sealed bottle for your safety protection.(http://tinyurl.com/3597e4t)
