The technique that includes the use of twists is natural hairstyling techniques. This approach focuses on maintaining the hair's natural texture and type without using harsh chemicals or heat that can alter its innate curl pattern. Twists are a common method within natural hairstyling that involves twisting two strands of hair around each other to create a style that not only looks appealing but also helps to protect the hair.

Layering involves cutting techniques that create different lengths in hair to add volume and shape, while texturizing pertains to modifying the hair's structure and can involve thinning or adding movement through cutting techniques. Perming employs chemicals to create curls or waves in straight hair, which does not align with the natural styling emphasis or the twisting technique associated primarily with natural textures. Thus, the use of twists solely fits within the realm of natural hairstyling techniques, making it the correct choice.
