Is this oil suitable as a leave-in conditioner, or should it be washed out?

MedicalFort Burdock Oil for Hair with Castor Oil is designed primarily as a pre-wash treatment. The texture, which combines lighter burdock oil with thicker castor oil, is especially suitable for applying to dry or damp hair before washing. This allows the nourishing lipids from the burdock oil and the protective layer from the castor oil to penetrate the hair shaft and scalp area. After leaving it on for a period (typically 20 minutes to an hour, or even overnight for intense treatment), you then shampoo and condition as usual to wash it out. This process helps soften the hair shaft, reduces the rough feel of damaged ends, and can leave hair looking smoother and more glossy after washing. Using it as a leave-in treatment on damp hair is possible, but due to the richness of the castor oil, it should be done with extreme moderation—a single drop worked through the ends—to avoid weighing hair down or making it appear oily, especially if your hair tends to be fine or gets oily quickly.
