What does hair texture refer to?

Hair texture refers specifically to the thickness or diameter of individual hair strands. It is an important characteristic that can significantly affect how hair behaves and responds to various styling techniques and products. For instance, coarse hair textures may require different care routines compared to fine hair textures due to differences in porosity, moisture retention, and styling needs. Understanding hair texture helps stylists provide customized services that enhance the appearance and manageability of their clients' hair.

In the context of the other options, while color variations deal with the pigmentation and aesthetic appearance of hair, and the curl pattern pertains to the shape and formation of the hair strands, these aspects do not define texture itself. Additionally, overall health is related to the condition and vitality of hair but does not directly correlate with the physical attribute of diameter or thickness, which is what texture encapsulates.
