What is the characteristic feature of a long layered haircut?

A long layered haircut is defined by its significant length difference between the layers. This technique creates movement and texture within the hair while maintaining overall length. The layers are strategically cut to allow for a softer appearance, making it easier to style and manage without losing the length that many clients desire.

The other options reference different techniques or haircuts. An evenly cut style at 0 degrees typically results in a blunt look, which does not apply to the layering technique. Cutting at 90 degrees is usually associated with creating volume but is not specific to a long-layered haircut in terms of the distinguishing feature of length between layers. Lastly, having short hair in the back with longer layers in front describes an entirely different haircut, often referred to as a graduated bob or an angled cut, rather than a layered haircut.

Thus, the defining characteristic of significant length differences between the layers is crucial for achieving the desired texture and movement characteristic of long layered hairstyles.
