Which term defines a haircut with very short hair in the back and longer hair in the front?

The term that describes a haircut characterized by very short hair at the back and longer hair in the front is referred to as a wedge haircut. This style typically features a graduated effect, where the hair is cut shorter towards the nape of the neck and gradually becomes longer as it moves towards the front. The wedge haircut creates a dramatic silhouette, adding volume and movement to the hair, making it a popular choice for many. The contrast between the back and the front is one of its defining features, resulting in a chic and modern look that can be customized in various ways depending on personal preference.

Alopecia refers to hair loss rather than a specific haircut style. A bob haircut is generally characterized by being of equal length around the head, often aligned with the jawline, and does not incorporate the back-to-front length difference. A layered haircut involves various lengths throughout the hair to add texture and volume but does not specifically define the short back and long front configuration that a wedge haircut does.
