Which term describes the hair's ability to stretch and return to its original shape?

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

Answer: (B)

Elasticity describes hair's ability to stretch and return to its original shape. When hair has good elasticity, it can be stretched during processing without breaking and will spring back afterward, showing resilience essential for chemical texturizing. Texture is about how the hair feels on the surface, density refers to how many hairs grow in a given area, and rod size relates to the tool used to wrap hair and influence curl, not how the hair stretches.
