In hairstyling, understanding the structure of shapes is essential for creating various styles. The oblong shape, which resembles an elongated oval, has two ends: a convex end and a concave end. The second direction or the bottom half of the oblong shape typically moves toward the concave end.

This movement is significant because working toward the concave end allows for the desired curvature and shaping of hair, helping to create soft, flowing lines in a hairstyle. When stylists design a hairstyle, they manipulate the hair to follow these contours, ensuring that the final look aligns with the intended style.

The concave end naturally guides the hair's movement, helping to create volume and bounce while maintaining a harmonious appearance. In contrast, the other options, such as the convex end or flat end, do not provide the same type of directional flow needed to create the desired fluidity in hairstyles. Thus, moving toward the concave end aligns with the principles of shaping and styling within the hairstyling discipline.
