Overprocessing hair refers to subjecting it to excessive chemical treatments, such as coloring, perming, or relaxing, which can lead to significant damage. When hair is overprocessed, the cuticle—the outer protective layer of the hair—becomes weakened and can even lift, exposing the inner layers. This often results in hair that is dry and brittle, as the natural moisture is stripped away.

Breakage is a direct consequence of this weakened state because the hair strands lose their elasticity and strength, making them more prone to snapping and splitting. Additionally, the lack of moisture can lead to a dry, rough texture, leaving the hair looking unhealthy and lifeless. Thus, breakage and dryness are indeed common and serious effects of overprocessing, making this the correct answer.

The other choices, such as enhanced shine, improved texture, and natural curl enhancement, suggest positive outcomes that are generally not associated with overprocessing. These effects are more likely to occur with proper hair care and treatment rather than excessive chemical manipulation.
