What is often a sign of over-processing in hair color treatments?

Loss of elasticity is indeed a common sign of over-processing in hair color treatments. When hair undergoes too much chemical processing—such as bleaching, coloring, or perming—it can disrupt the hair's natural structure. This often leads to damage in the protein bonds that give hair its strength and resilience. As these bonds break down, the hair becomes more fragile and loses its ability to stretch and bounce back, which is what elasticity measures.

In healthy hair, elasticity allows it to endure styling tensions and recover its shape without breaking. When elasticity is compromised due to over-processing, the hair may also become more prone to breakage and split ends, leading to an overall unhealthy appearance. Observing a loss of elasticity can prompt professionals to reassess the frequency and methods of treatment to prevent further damage and maintain the hair's health.
