Which type of curls is commonly referred to as "stand up curls"?

Cascade curls are commonly referred to as "stand up curls" because they create a voluminous effect that lifts away from the scalp and stands taller, providing an elegant and dynamic hairstyle. This type of curl is achieved by wrapping the hair around a roller or curling tool in such a way that the curls are positioned to stand upright. This technique adds height and body to the hair, making it appear fuller and more glamorous. Cascade curls are particularly popular for special occasions or when a bouncy, lively look is desired.

The other types of curls, while they have their own unique characteristics and techniques, do not typically result in the same effect. Spiral curls are more defined and create a corkscrew shape; pin curls are small, flat curls pinned to the scalp for a vintage look; and twist curls involve twisting sections of hair for a different texture that doesn’t usually 'stand up' in the same manner as cascade curls. Each of these styles has its place, but cascade curls are specifically recognized for their upright, voluminous appearance.
