What does elasticity describe in hair?

• A. The hair's tendency to kink and tangle
• B. The ability to stretch and return to its original shape without breaking
• C. The capacity to absorb moisture
• D. The measure of curl pattern

Answer: (B)

Elasticity describes how hair behaves when you pull on it: its ability to stretch and then return to its original length without breaking. This property shows how strong and resilient the internal bonds in the hair are and how well the cortex and cuticle hold together after stress. Healthy hair with good elasticity can stretch noticeably and then snap back, whereas hair with poor elasticity may remain stretched or break when pulled. That’s why describing elasticity as the hair’s ability to stretch and return to its original shape without breaking is the best fit. The other descriptions refer to different traits: kink or tangling relates to texture, moisture absorption to porosity, and curl pattern to the hair’s shape.
