The technique used to achieve curls in straight hair is through the use of curling irons or rollers. This method is effective because both curling irons and rollers provide heat or support that shapes the hair into curls.

When utilizing curling irons, the stylist wraps sections of hair around a heated barrel, allowing the heat to alter the hair's structure temporarily, creating defined curls that can vary in size based on the diameter of the iron used. Similarly, rollers can be used with or without heat, depending on the desired style. When using heated rollers, they heat the hair as they set, leading to voluminous, lasting curls.

Blow drying, while it can add volume and some wave, is not specifically designed to create curls like curling irons or rollers. Straightening with a flat iron straightens hair rather than curls it, and braiding hair overnight may create waves or a loose texture but is not as controlled or defined as curls created with curling tools. Thus, the most direct and effective technique for achieving curls is indeed the use of curling irons or rollers.
