What is the outcome of over-processing hair with chemical treatments?

Over-processing hair with chemical treatments leads to weakness and potential hair breakage because the hair structure is compromised during these processes. Chemical treatments, such as bleaching, perming, or relaxing, alter the hair's natural structure and can strip it of moisture and essential nutrients. When hair is over-processed, the cuticle layer becomes damaged, resulting in an inability to retain moisture and increased porosity. This deterioration can weaken the hair shaft, leading to brittleness and breakage.

In contrast, other potential outcomes like increased volume, strength and luster, or improved texture are unlikely when hair is over-processed. Increased volume may occur in some treatments, but over-processing typically results in flat, lifeless hair rather than volume. Strength and luster are usually reduced, not improved, and while texture may initially appear altered, over time it tends to become rough and unmanageable due to damage.
