In hair cutting, what is the purpose of using a wig block?

The primary purpose of using a wig block during hair cutting is to hold the wig still for cutting. This is essential for achieving precision and accuracy in the haircut. When a wig is secured on a wig block, it remains stable, allowing the stylist to work on the hair without interruptions that may occur if the wig were simply laid flat or held by hand. This stability ensures detailed work on the haircut, such as layering or texturizing, can be carried out effectively.

While the other options present valid uses for a wig block in different contexts—like displaying or sizing a wig—these are not its primary function when it comes to hair cutting. The wig block is specifically designed to facilitate the cutting process, making it an invaluable tool for stylists seeking to deliver high-quality results.
