Using a curling iron or hot rollers is an effective method for achieving curls or waves in straight hair. This technique involves using heat to change the structure of the hair temporarily. Curling irons work by wrapping sections of hair around a heated barrel, which creates defined curls. Hot rollers, on the other hand, are heated devices that can be rolled into the hair; as they cool, they set the curls in place.

Both tools provide variety in the size and type of curls that can be created, from tight ringlets to loose waves, making them versatile options for styling. By applying heat, these methods break the bonds in the hair's structure and allow them to form a new, curled shape, which results in a voluminous and textured appearance.

The other options do not effectively achieve the desired curls or waves. Using a blow-dryer with a brush may create some volume and movement, but it typically does not produce lasting curls. Flat ironing the hair straightens it and adheres to a sleek style, while using scissors merely alters the hair's length and shape, having no impact on creating curls or waves.
