Which of the following tool positions is not used in curvature volume?

In the context of hairstyling, curvature volume refers to techniques used to create volume and shape in the hair, often through the use of various tool positions during the styling process. Understanding tool positions helps stylists achieve the desired look and texture in their work.

Overdirected positioning involves directing the hair away from its natural fall, which can create lift and volume, making it a common technique used to build curvature volume.

In contrast, the underdirected position pulls the hair in the opposite direction to its natural fall, often leading to a more flattened appearance, which does not contribute to volume in the same way. Vertical placement typically allows for elongated shapes and movement, while horizontal placement can add width and dimension, both of which can enhance volume.

Since overdirected is a method actively used to create volume, it aligns well with the goals of curvature volume techniques. Choosing it as the option that is not used is incorrect, as it is actually relevant. Understanding the correct relationships between these tool positions and their effects on hair volume helps stylists select the right techniques for their desired outcomes.
