The process of removing dust, dirt, and product buildup from hair is achieved through what practice?

The practice that effectively removes dust, dirt, and product buildup from hair is hair brushing. Brushing the hair helps to distribute natural oils from the scalp along the hair shafts, which can enhance the overall health and appearance of the hair. Additionally, brushing can help to detangle hair, smoothing it and preventing knots and breakage. This action also loosens and removes any accumulated debris, allowing for cleaner hair that is ready for styling or further treatments.

On the other hand, hair cutting focuses on altering the length and shape of the hair, which does not contribute to cleaning it. Hair coloring involves applying dyes to change the color of the hair, and hair curling is a styling technique that creates curls or waves. Neither coloring nor curling serves the purpose of cleansing the hair, making brushing the most suitable option for this particular task.
