Which bang style is typically not suitable for all hair lengths?

Side-swept bangs are generally not considered suitable for all hair lengths due to their specific styling requirements. They are typically designed to be longer on one side and shorter on the other, which means they often work best with longer hair that can support this asymmetrical style. For shorter hair, achieving a side-swept look may not be as feasible, as the hair may not have the necessary length to create the desired effect. Additionally, the styling of side-swept bangs can often rely on the weight and volume of longer hair to hold the shape and allow for movement, which may not translate as effectively with shorter cuts.

In contrast, styles like blunt bangs, curtain bangs, and wispy bangs can be adapted to a variety of hair lengths. Blunt bangs can be cut to any desired length and can frame the face regardless of the hair's overall length. Curtain bangs offer versatility, as they can blend with both long and short styles, and wispy bangs can be tailored to suit virtually any hair length with a soft, feathery texture.
