What part of the finger wave is located directly underneath the ridge?

The correct answer is the hollow. In a finger wave, the hollow refers to the area that is located directly underneath the ridge. Understanding the structure of a finger wave is essential for hairstyling, as it helps create the desired wave pattern.

The ridge is the prominent, raised part of the wave, while the hollow is the indentation that lies directly beneath it. This arrangement adds dimension and shape to the hairstyle, allowing for fluid movement and a polished finish.

Grasping the roles of these parts is vital for anyone practicing hairstyling techniques, as it aids in effective wave creation and overall hairstyle design. Recognizing the function of the hollow helps ensure that the waves formed are evenly structured and visually appealing.
