The side part lob is a medium length haircut that falls between the chin and shoulders. Lob is short for “long bob,” which refers to a bob haircut that maintains extra length. This hairstyle works well for round faces because the side part introduces asymmetry, which breaks the natural symmetry of the face.

The concept behind the side part lob focuses on directing the hair across one side of the face. This directional styling creates a diagonal visual line that helps elongate facial proportions. The length of the lob also prevents the hair from ending directly at the cheeks, which could emphasize roundness.
