Two or more alternating oblongs create a(n):

The formation created by two or more alternating oblongs can indeed be described as an S shape. This shape is characterized by a smooth, flowing curve that resembles the letter "S," which is achieved by the way the oblongs alternate their placements and directions.

In hairstyling, this S shape can be particularly relevant as it influences the overall movement and texture of the hairstyle. The alternating oblongs create dimensions and waves that are visually appealing, allowing for more dynamic and full hairstyles.

Other shapes, such as W or C, do not accurately represent the configuration of alternating oblongs. The W shape has distinct peaks and valleys that would not be formed with simple alternating oblongs. The C shape is more rounded and would not show the same flowing transition as the S shape, while a circle shape suggests a closed and uniform roundness, which does not mirror the dynamics of the alternating oblongs. Thus, identifying the resulting shape as an S is correct based on the specific arrangement of the oblongs.
