Chemically treated hair is more prone to damage when over-processed due to the alterations it has already undergone through chemical applications such as coloring, relaxing, or perming. These processes break down the hair's protein structure, making it weaker and more susceptible to further damage from additional chemical treatments or heat styling.

When hair has been chemically treated, it has already lost some of its natural moisture and strength. As a result, further processing can lead to issues like brittleness, breakage, and excessive dryness. Proper care and maintenance are crucial for chemically treated hair to help restore and retain its health, further highlighting the importance of minimizing additional processing and utilizing protective products.

In contrast, virgin hair has not been exposed to any chemicals, making it generally more resilient. Natural hair refers to hair in its original state, which may also be less affected by processing. Curly hair can be prone to certain types of damage, but the extent of damage is closely tied to the treatment and manipulation rather than the inherent texture itself. Therefore, chemically treated hair stands out as the most vulnerable to the adverse effects of over-processing.
