In styling, what does the term "setting" refer to?

The term "setting" in styling specifically refers to the technique of creating curls or waves that hold their shape. This process typically involves the use of tools such as rollers, curling irons, or setting lotion to help define and secure the hairstyle. When hair is set properly, it can achieve a structured look that lasts longer, as the shape is supported by the setting process.

The other options describe different aspects of hairstyling but do not capture the essence of "setting." For example, cutting hair pertains to the transformation of length and shape rather than the creation of curls or waves. Additionally, enhancing shine is focused on product usage, which does not involve the setting of a style. The application of hair dye is related to coloration and is not directly concerned with shaping or styling the hair. Therefore, the correct answer accurately encapsulates the meaning of setting in the context of hairstyling.
