What does "over-processing" in hair services primarily lead to?

Over-processing in hair services refers to the excessive application of chemical treatments such as coloring, perming, or relaxing, which can strip the hair of its natural moisture and proteins. This process weakens the hair structure, leading to significant damage.

When hair is over-processed, it often becomes dry, brittle, and prone to breakage. The cuticle layer of the hair, which protects the inner structure, can become compromised, resulting in increased frizz, split ends, and a lack of elasticity.

The other options present outcomes that are typically not associated with over-processing. Improved hair texture, enhanced color retention, and increased hair volume are desirable effects that may result from the correct application of products and techniques, but excessive processing does not lead to these results. Instead, the focus should be on maintaining the integrity of the hair to achieve healthy, manageable locks.
