The bottom half of the oblong shape, when analyzed in terms of hair styling or other beauty techniques, typically refers to the way sections of hair are formed and styled. The second direction of movement in an oblong shape corresponds with the overall flow and the structure of the curl or wave being created. Moving toward the concave end implies that the lower portion of the curl or wave is shaped inwards, creating volume and texture.

In many styling techniques, the concave end supports the formation of softer, more rounded curls or waves. This approach creates a visually appealing and balanced look, as it emphasizes the curves and softness that clients often desire. The stylist's choice to direct the hair toward the concave end is essential in achieving this desired finish.

The other options represent concepts that do not accurately describe the movement associated with the bottom half of the oblong shape. This is why focusing on the concave end is crucial for achieving the correct look in numerous hairstyling methods.
