Which term describes the diameter of a single strand of hair?

• A. Hair texture
• B. Hair density
• C. Hair elasticity
• D. Hair porosity

Answer: (A)

The diameter of a single strand is described by hair texture. Texture refers to how thick each strand is, usually noted as fine, medium, or coarse. Dense lighting or feel of the hair isn’t about how many hairs are on the scalp; that’s density. Elasticity is how much the hair can stretch and return to shape, while porosity describes how easily moisture moves into and out of the hair. So when you’re talking about the actual thickness of an individual strand, texture is the term that fits.
