Summarize the following:
The only general rule to oiling your hair is that you should comb through it to prevent tangling and messy oil application. Beyond that, there's debate over whether hair should be clean when oiled. Some swear that oiling works better when the hair is already a little bit oily and dirty say two or three days after your last shampooing. Others insist that oiling works best soon after you've shampooed your hair when it's clean and bare. Try it both ways to decide what you prefer. Especially if you're new to oiling your hair, there's a good chance you're going to make a mess. Spread old towels or paper towels around the area where you're going to work. This includes table surfaces and floors. Have an extra hand rag available for spot-cleaning drippy messes. If you're going to sleep with oil in your hair, protect your pillows with plastic pillowcase coverings.
Prepare your hair. Protect the area from oil splatter.
