I have never used any kind of oil in my hair since my hair is fine, and gets oily quickly. I was hesitant, but tried in anyways. I loved it. My hair looks healthier at the ends, and less frizzy. As long as I do not use it close to the root, it does wonders for my hair, and does not leave my hair looking greasy or too heavy. I also love the earthy smell. Will be buying the full size product soon.
