What does "hair volume" refer to?

Hair volume refers to the amount of space that the hair occupies and its perceived fullness. This concept is crucial in applied salon practice because it impacts hairstyle choices, haircuts, and the application of various styling techniques. High volume hair often appears fuller and bouncier, while low volume hair may look flatter.

Understanding hair volume helps stylists make informed decisions when it comes to layering, creating body, or adding products that enhance fullness. For instance, certain techniques like teasing or using volumizing products are intended to increase the volume of hair by manipulating its structure and shape.

Other aspects like hair length, color intensity, and texture play essential roles in the overall appearance and styling of hair but do not define volume itself. Length pertains to how long the strands are, color intensity relates to how vivid or deep the hair color appears, and texture describes the surface quality of the hair (whether it’s coarse, fine, or smooth). Therefore, option B accurately captures the essence of what hair volume encompasses.
