What is the main purpose of using a Barrel Curl in hair design?

The main purpose of using a barrel curl in hair design is to support hair design prior to finishing. Barrel curls are typically used to provide volume, structure, and shape to a hairstyle, allowing for a more polished and intricate final look. These curls can act as a foundation for various hairstyles, enhancing texture and allowing stylists to create a rounded shape that can be manipulated further. By setting the hair this way, it holds additional styling products better and can contribute to a long-lasting finish.

In contrast to the other options, tight curls are more specifically associated with techniques that focus on smaller, tighter sections of hair, while straightening and adding color serve entirely different functions in hair design. The primary role of the barrel curl as a foundational element underscores its importance in the styling process, making it an essential technique for achieving a cohesive and well-finished hairstyle.
