How can you determine if hair is damaged?

Determining if hair is damaged can effectively be assessed by evaluating its texture and appearance. Damaged hair typically exhibits specific characteristics such as increased brittleness, roughness, or a lack of smoothness in texture. Additionally, its appearance might include split ends, frizz, or an overall dullness, indicating that the hair is no longer healthy.

While other options may provide some insights—such as color and shine, which can suggest health under certain conditions—texture and appearance offer a more direct assessment of the physical state of the hair. Length and thickness are more related to hair growth and density rather than direct indicators of damage. Smell and feel can also hint at hair condition, but they are less reliable for determining structural damage than texture and visual cues.
