An on-base tool position will result in the strongest base strength and:

The choice of maximizing volume when using an on-base tool position is based on the fundamental principles of hair styling. An on-base tool position means that the tool is positioned directly on the base of the hair strand, which elevates the hair away from the scalp. This technique allows for more lift and fullness, particularly at the roots, resulting in a voluminous appearance.

When the hair is curled or set in this way, the curls or waves start closer to the scalp, thus adding height and body. This technique is particularly effective in achieving a dramatic, full-bodied style that many clients desire, especially when creating shapes that require substantial volume at the crown, such as updos or big, bouncy hairstyles.

In contrast, while using tools in off-base or half-base positions may create different effects, such as reducing volume or producing softer styles, the on-base position is specifically designed to optimize lift and enhance volume.
