Applying castor oil to hair seems like it might be simple, but there are a few things you can do to make it more effective and easier to apply. Here is a list of what you will need:  Castor oil Other oil (argan, avocado, coconut, jojoba, sweet almond, etc.) Hot water Bowl Jar Shower cap Towel Old shirt (recommended) Castor oil is fairly thick. Mixing it with another oil can make it a little easier to apply. Try using one part castor oil and one part of another oil, such as argan, avocado, coconut, jojoba, or sweet almond. All of these oils are great for hair. You can also try the following combination:  3 tablespoons (44 ml) castor oil 1 tablespoon (15 ml) jojoba oil 1 tablespoon (15 ml) coconut oil Castor oil can smell bad. If this bothers you, try adding in two to three drops of a fresh-smelling essential oil, such as rosemary, peppermint, or tea tree. Close the lid tightly, and shake the jar for a few minutes. When you are done, take the lid off. You can do a “hot oil treatment” with castor oil by warming it in hot water before use. Warming the oil will make it more effective and easier to work with. Make sure that the bowl you choose is large enough for the jar of castor oil to fit inside. Do not attempt to warm the oil in the microwave. Make sure that the water level is at the same level as the oil. Also, make sure that the no water gets inside the jar, or the oil will get wet. This will make it easier for you to dip your fingers into when you go to apply it.  Consider pouring the oil into a small bottle with an eye dropper. This way, you can use the eye dropper to just drip the oil to your scalp. If you don’t have an eye dropper, you can use a bottle with a nozzle. You can get empty applicator bottles from most beauty supply stores.
