Arranging hair is an important part of styling and can involve a variety of techniques. The term 'arrange hair' can be broken down into five distinct tasks: styling, sorting, setting, coifing, and smoothing. Styling involves creating a desired look or shape with the hair, such as a braid or updo. Sorting involves separating the hair into sections to make it easier to work with. Setting involves using tools such as curlers or rollers to create a desired shape. Coifing involves using products such as gels or mousses to hold the hair in place. Finally, smoothing involves using a brush or comb to make the hair look sleek and shiny.
