What does a lack of elasticity in hair often indicate?

A lack of elasticity in hair often indicates that the hair has become dry or damaged. Elasticity in hair refers to its ability to stretch and return to its original shape without breaking. When hair is healthy, it possesses good elasticity, allowing it to withstand styling and environmental factors. However, when hair becomes dry or damaged due to factors such as heat styling, chemical treatments, or environmental stressors, it can lose its moisture and natural structure. This results in brittle hair that is unable to stretch properly, leading to breakage and split ends. Recognizing a lack of elasticity is crucial for identifying hair health issues and determining the necessary treatments to restore its vitality.
