Which tool position is used in perimeter areas where closeness is desired?

The tool position used in perimeter areas where closeness is desired is "under directed." This technique involves placing the tool below the parting, which helps achieve a tighter curl or wave in the hair. By directing the hair under the base, the resulting style will be closer to the scalp, creating a more defined and structured look. This position is especially effective for adding volume and control in the perimeter, making it ideal for achieving desired styling results in those specific areas.

Other tool positions, such as "on base" or "half off base," would yield different curl placement and volume effects, which may not provide the same level of closeness and definition in the perimeter region. "Off base" positioning generally results in curls that are looser and further from the scalp, which is contrary to the goal of obtaining tightness and definition in the perimeter areas.
