I think coconut oil is great for sealing AND lubricating. Some folks do find it moisturizing, but most agree that only water or water based products can do that. So if you spray with moisture and follow with some coconut oil, you're doing your hair a huge favor.
It's good to eat too. I like to put a few tsp into my Korean Noodle soup. YUM!!
You can keep to separate containers or just keep your fingers out of the container and use a scoop whether for your hair or your meals.
