Damaged hair typically presents with roughness and split ends, which are clear indicators of its compromised structure. When hair is healthy, it usually has a smooth texture and a natural shine due to its intact cuticles, which reflect light effectively. High elasticity is another sign of healthy hair; it indicates that the hair can stretch and return to its original shape without breaking. However, when hair is damaged, it loses its elasticity, resulting in brittleness and an inability to hold its shape, alongside the visual signs of roughness and split ends. This roughness occurs because the outer layer of the hair (the cuticle) becomes frayed or lifted, while split ends emerge from continued wear and lack of moisture. Thus, the presence of rough hair texture and split ends is a direct manifestation of damage, making this the correct choice.
