The technique of wrapping hair at a 90-degree angle or straight out from the center is known as half off base placement. This method involves positioning the hair sections perpendicular to the base, which creates a balance between volume and control.

Understanding different base placements is crucial for cosmetologists, as it affects the overall outcome of perming or styling treatments, influencing both texture and volume in the finished hairstyle.
