Over-processing hair involves subjecting it to harsh chemical treatments, excessive heat styling, or frequent coloring, leading to significant damage. The common effect of this damage is characterized by dryness and breakage. When hair is over-processed, the cuticle—the outer protective layer of the hair—becomes weakened and may lift, exposing the inner layers to moisture loss and environmental damage. This not only causes the hair to become brittle and more prone to breakage but also leads to an overall dry appearance and texture.

Healthy hair maintains a certain level of moisture and elasticity, allowing it to withstand daily wear and tear. However, once over-processing occurs, the natural moisture retention ability is compromised, resulting in a lack of elasticity, which is essential for maintaining hair's structural integrity.

Strengthened hair and improved color retention are typically outcomes associated with proper hair care practices and protective treatments rather than over-processing. Thus, understanding the impact of over-processing is critical for maintaining healthy hair and preventing unwanted damage.
