The term "overprocessing" refers specifically to excessive treatment that leads to damage in hair. This condition typically occurs when hair is subjected to harsh chemicals, such as those found in hair dyes, relaxers, or perm solutions, more often than the hair can withstand. The result of overprocessing is often weakened hair structure, which can manifest as brittleness, breakage, and a loss of elasticity.

This concept is crucial for anyone involved in hair treatment and styling, as it highlights the importance of balancing the benefits of desired treatments with the integrity of the hair. Proper training and experience are essential for identifying the signs of overprocessing and for applying hair treatments in a way that minimizes damage, thus preserving hair health. By understanding the implications of overprocessing, cosmetologists and hairstylists can make informed choices that protect their clients' hair.
