Utah Cosmetology and Barbering Exam 2025 – Complete Preparation Guide

The main purpose of a blow dryer in styling is to speed up drying and shape the style. When heat is applied through a blow dryer, it evaporates the moisture in the hair quickly, allowing for a more efficient styling process. This enables hairstylists to manipulate the hair into the desired shape and form while also providing the necessary drying time that prevents frizz and maintains the hair's texture.

Additionally, as the stylist uses the blow dryer, they can employ various techniques such as round brushing or diffusing to create specific styles—whether it be smooth and sleek finishes or voluminous curls. This versatility makes the blow dryer an essential tool in both everyday and professional hair styling.

While it is true that a blow dryer can help with adding volume and may assist in straightening hair when used in conjunction with brushes or flat irons, the primary function relates directly to the drying and shaping process itself rather than solely focusing on enhancing volume or straightening.
