Which type of haircut is known for adding volume to the hair?

A layered haircut is well known for adding volume to the hair. This technique involves cutting the hair at varying lengths, which creates movement and texture, making the hair appear fuller and bouncier. By removing weight from certain sections while leaving other sections longer, layers can enhance the natural body of the hair, especially for those with fine or thin hair.

In contrast, a blunt cut typically creates a straight edge all around the hair, which can sometimes make hair look heavier and less voluminous. A long bob, while stylish and versatile, doesn’t inherently focus on layering techniques that build volume as effectively as a layered haircut. An asymmetrical cut can provide a unique shape but doesn't necessarily contribute to overall volume in the same way layers do.
