What technique is characterized by intertwining multiple strands of hair to form a continuous design?

The technique characterized by intertwining multiple strands of hair to form a continuous design is known as braiding. Braiding involves taking three or more sections of hair and intertwining them in a pattern to create a unified look. This technique is commonly used in various hairstyles, creating everything from simple three-strand braids to complex designs, and can add texture and visual interest to a hairstyle.

In braiding, the strands are consistently woven over and under one another, which allows for a cohesive look. This method is integral to many traditional and contemporary styles, and can vary in thickness and complexity depending on the desired outcome. The results can be both functional, in keeping hair styled and managed, as well as decorative, showcasing creativity and skill.
