Final answer:
The hair styling technique that creates a candy cane effect by overlapping two strands is called twisting. This technique differs from braiding, cornrowing, and weaving, which produce varying patterns and textures in hairstyles.
Step-by-step explanation:
The technique that involves overlapping two strands to create a candy cane effect in hair styling is known as twisting. This method can be used to create decorative hair styles with a spiral, intertwined appearance that resembles the iconic red and white stripes of a candy cane. While braiding and cornrowing also involve overlapping strands of hair, they typically produce different patterns and textures. Weaving, on the other hand, may refer to a process that includes integrating hair extensions into one's hair, which is not directly related to creating a candy cane effect.
