Which factor does not always match hair texture?

• A. Texture
• B. Elasticity
• C. Hair Density
• D. Perm Rod Size

Answer: (C)

Texture describes the thickness of each individual strand, but not all hair properties follow that same pattern. Hair density, or how many hairs occupy a given area, can vary independently of strand thickness. So you can have fine hair with high density or coarse hair with low density, meaning density doesn’t always align with texture. Elasticity and perm rod size relate more to how hair behaves during processing and styling and tend to correlate with how hair holds shape, whereas density is about quantity, not diameter, which is why density stands out as the factor that doesn’t necessarily match texture.
