Question: 1 / 400

What is a common cause of hair breakage?

Underwashing the hair

Over-processing with chemicals

Over-processing with chemicals is a common cause of hair breakage because chemical treatments, such as coloring, perming, or relaxing, can weaken the hair structure. These processes alter the hair's natural protein and moisture balance, making it more susceptible to damage. When hair is over-processed, the cuticle layer, which protects the inner structure of the hair, can become compromised, leading to increased brittleness and breakage.

While other options might contribute to hair health, they do not have as significant an impact on the structural integrity of hair as excessive chemical treatments. For example, underwashing the hair or not getting regular trims may affect cleanliness or split ends, and using too much conditioner can lead to buildup, but none are as directly tied to the weakening of the hair shaft as over-processing is.
