What is the primary movement style used in hacking during a haircut?

The primary movement style used in hacking during a haircut is a chopping movement. This technique involves using the shears or scissors in a way that creates a distinct, textured effect in the hair. Chopping is characterized by quick, forceful motions that allow the stylist to remove bulk from the hair and create layers or a choppy finish. This technique is particularly useful when working with thick hair or when a stylist wants to achieve a more edgy or modern look.

In contrast, other movements such as slashing may imply a more aggressive approach that may not achieve the desired softness and texture. Clipping is typically associated with the action of using clippers rather than scissors, and rolling tends to refer to a specific method of curling or comfort handling rather than cutting technique. Therefore, the chopping movement is ideal for creating the unique, textured looks that hacking is known for, making it the correct choice in the context of haircutting techniques.
