Hemp Seed Oil - Cold Pressed Unrefined for Skin and Hair This natural Hemp Seed Oil - Cold Pressed Unrefined product is Unrefined, which means it is in the purest form. To obtain Hemp Seed Oil, the seeds of the Hemp plant, are cold-pressed to extract the oil. Cold pressing involves physically pressing the seeds without using any heat to extract the oil. More importantly, the oil is then left unrefined (also referred to as raw) so that it is still nutrient-rich.  The main interest in hemp seeds (also known as hemp hearts) and the seed oil is the balanced content of essential omega-3 and omega-6 fatty acids. When used topically, these acids help nourish and restore skin and hair, thereby promoting a healthier appearance. Many people are trying seed oil as a cosmetic and find that they love it!
