Which style utilizes both finger and comb techniques for hair styling?

The correct choice emphasizes the unique integration of finger and comb techniques specifically characteristic of coils or comb twists. This styling method involves using fingers to aid in twisting the hair while also employing a comb to part the sections accurately. This combination allows for a defined and textured look, enhancing the natural curl pattern of the hair.

In contrast, cornrow braids are typically created with a continuous braid that is woven closely to the scalp using only the fingers for technique. Double-strand twists focus on twisting two strands of hair together and are primarily executed with fingers as well, lacking the comb's involvement. Bantu knots are formed by twisting the hair and wrapping it into small knots, relying mainly on finger manipulation rather than a combination of comb techniques. This highlights the distinctive nature of coils or comb twists, making it the correct response.
