It is rumored that the ancient Egyptians were the first to discover the many uses of castor oil.  Castor oil is comprised mainly of fatty ricinoleic acid and works as an emollient for rough dry skin. It can provide a barrier on the skin and protect against moisture loss. For hair, it is also a lubricant that conditions strands to improve smoothness and shine.   Castor oil contains Vitamin E, proteins and Omega 6 & 9 that are the key components responsible for good hair and skin.
