What is typically a sign of damaged hair?

1. Extra shine

2. Increased elasticity

3. Breakage

4. Low porosity

The correct answer is: Breakage

Breakage is a clear indicator of damaged hair. When hair is healthy, it possesses a degree of elasticity that allows it to stretch without breaking. However, when the hair shaft becomes weakened due to factors like excessive heat styling, chemical treatments, or environmental damage, it loses its structural integrity, leading to breakage. This fragility can manifest as split ends or hair falling out in strands, making breakage a prominent sign of compromised hair health. In contrast, features like extra shine typically indicate healthy hair, as shine results from a smooth cuticle layer reflecting light. Increased elasticity suggests that the hair is healthy and able to return to its original shape after stretching, displaying good moisture content and resilience. Low porosity refers to the hair's inability to absorb moisture effectively, which can signify certain types of damage but is not a direct indicator like breakage is. Thus, recognizing breakage is critical in assessing and addressing the health of hair.
