What does the term 'texture' of hair relate to?

The term 'texture' of hair specifically refers to the shape and diameter of individual strands of hair. This encompasses how fine, medium, or coarse a person's hair might be, as well as whether the hair is straight, wavy, or curly. Understanding hair texture is crucial for estheticians and those in the beauty industry, particularly when it comes to choosing the right products and techniques for hair removal or styling.

The other options do not accurately represent the definition of hair texture. For instance, the color of the hair pertains to the pigmentation and hue, while the number of hair strands relates to density rather than texture. The growth rate of hair involves how fast hair grows over time, which is unrelated to the texture itself. Thus, identifying texture is essential for assessing and tailoring treatments effectively in waxing and other hair care practices.
