Which characteristic describes wavy hair texture?

Wavy hair texture is defined by its gentle curves, which create a soft, undulating pattern. This texture lies between straight and curly hair, often exhibiting a loose wave that gives it volume and movement. The key aspect of wavy hair is its ability to form these subtle, S-shaped waves without becoming tightly coiled, which distinguishes it from curly hair that has more defined curls. Understanding this characteristic is crucial for hairstyling and treatment, as different hair textures require different approaches to care and styling. The other options do not accurately describe wavy hair, as they pertain to straightness, curl definition, or frizziness, which do not represent the unique qualities of wavy hair texture.
