What type of hairstyle typically requires blow-drying for optimal shape?

Blow-drying is an essential technique for achieving the best shape and volume, particularly with layered cuts or bobs. These styles often benefit from the added lift and definition that blow-drying provides. The process allows stylists to manipulate the hair's texture, creating movement and enhancing the layered structure, which can sometimes fall flat when air-dried.

In contrast, long straight hair typically maintains its shape more easily without the need for blow-drying, as it naturally falls and can look sleek with minimal effort. Curly hairstyles also rely on different techniques, such as scrunching and using diffusers, which are specific to enhancing the natural curl rather than relying on blow-drying for shape. Buzz cuts, being very short styles, do not require any blow-drying at all, as they are primarily maintained through clippers and do not need styling for shape. Thus, the layered cuts or bobs stand out as the hairstyle that truly benefits from the blow-drying process to achieve optimal shape and presentation.
