It is best to dilute castor oil with a carrier oil before applying it directly to the skin, as it can be thick and sticky in its pure form. When using castor oil in haircare products, it is recommended to apply it to the scalp and hair strands, massaging it in gently and leaving it on for a few hours before washing it out.
