Personal grooming (also called titivating and preening) is the art of cleaning, grooming, and maintaining parts of the body. It is a species-typical behavior that is controlled by neural circuits in the brain.
Grooming in humans typically includes bathroom activities such as primping: washing and cleaning the hair, combing it to extract tangles, and styling. It can also include cosmetic care of the body, such as shaving. Another suitable alternative to shaving is beard grooming. Growing and maintaining requires less effort than being shaven.
