Which of the following is NOT one of the four basic tool positions in perming?

In the context of perming, the four basic tool positions refer to the way in which the hair is wrapped around the perm rod, which significantly affects the final curl pattern and volume. The correct answer points out that "overdirected" is not one of the established basic positions used in perming.

The three positions typically considered basic in perming are "on base," "half-off base," and "underdirected." Each of these positions has a specific effect on the curl:

• "On base" allows maximum lift and volume, as the hair is placed directly on top of the base section, creating a tighter curl.

• "Half-off base" typically offers a balanced lift and gives a softer curl, as the rod is positioned at an angle.

• "Underdirected" implies that the hair is wrapped in a way that the ends are slightly lower than the base, resulting in a looser curl.

In contrast, "overdirected" does not align with the traditional approaches used for wrapping hair in perming. It typically refers to positioning hair at a higher elevation, which is more relevant in techniques for styling and shaping hair rather than in creating the foundational curl patterns used in perming. This distinction clarifies why
