Hair texture is determined by the diameter of individual hair _____.

• A. Follicles
• B. Hairs
• C. Strands
• D. Cuticles

Answer: (C)

Hair texture is determined by the diameter of the individual hair strands. The width of each fiber sets how fine or coarse the hair feels; thicker strands feel coarser, while thinner strands feel finer. The term strands refers to a single hair fiber, which is the unit whose diameter defines texture. The follicle is the root structure that produces hair and doesn’t set texture, and the cuticle is the outer protective layer; while the cuticle affects surface feel, texture is primarily about the fiber’s diameter. Using hairs would imply multiple fibers, not the texture of a single strand.
