What can result from over-processing hair during a chemical service?

Over-processing hair during a chemical service, such as coloring, perming, or relaxing, can lead to significant damage. When the hair is exposed to chemical solutions for too long or the wrong concentration is used, the hair's protein structure can be compromised. This results in damage that manifests as breakage, where the hair strands become brittle and susceptible to snapping, and a loss of elasticity, meaning the hair can no longer stretch without breaking.

While increased shine and softness, enhanced color retention, and improved texture are desirable outcomes from a chemical service, they can be overshadowed by the detrimental effects of over-processing. Once the hair is damaged, it often appears dull and lacks vitality, making the correct understanding of hair processing crucial to maintaining hair health.
