Overprocessing refers to the damage that occurs when excessive chemical treatments are applied to the hair. This can include practices such as repeated coloring, perming, or relaxing treatments that weaken the hair structure over time. The cumulative effect of these harsh chemicals can lead to dryness, brittleness, and even breakage, resulting in hair that is difficult to manage and style.

In contrast, while using heat styling tools frequently can also harm hair, it specifically pertains to heat damage rather than chemical damage, which is the core focus of the definition of overprocessing. Similarly, applying too much conditioner or neglecting to condition hair does not fall under the realm of overprocessing, as these actions involve product application rather than harsh chemical procedures. Understanding overprocessing is crucial for cosmetologists to maintain the health and integrity of their clients' hair while still achieving desired styles.
