Which term is used to describe the shape or pattern of the hair strand?

The term that describes the shape or pattern of the hair strand is "wave pattern." This refers specifically to the curls, waves, or straightness of the hair, which can significantly influence styling and treatment choices in waxing and other hair removal services. Understanding the wave pattern allows professionals to tailor their techniques to the specific requirements of different hair types.

On the other hand, texture refers to the thickness or diameter of the hair strands themselves, density pertains to how many hair strands grow in a given area (thinning vs. thick hair), and color relates to the pigmentation of the hair. While all these elements are important in the broader context of aesthetic treatments, it is the wave pattern that specifically addresses the shape and arrangement of the hair strands.
