What effect can improper chemical processing have on hair?

Improper chemical processing can lead to dryness and breakage of the hair due to the disruption of the hair's natural structure and moisture levels. When chemicals are applied incorrectly or are left on the hair for too long, they can strip the hair of its natural oils and weaken the protein structure. This results in brittleness, making the hair more prone to split ends and breakage. A well-balanced chemical treatment should improve the hair's texture without compromising its integrity, and any misapplication can have severe negative consequences on its overall health. The other options do not accurately reflect the potential damage caused by improper chemical processing. Increased shine and enhanced curl pattern are generally positive outcomes of proper treatments, while quick growth is not typically impacted directly by chemical processing methods.
