What is the potential consequence of an over-processed perm?

An over-processed perm occurs when the hair undergoes excessive chemical treatment, often resulting in weakened hair structure. This over-processing can lead to excessive damage and breakage, as the hair cuticle gets stripped of its natural oils and proteins. The chemical bonds that give hair its structure and integrity become compromised, making the hair more susceptible to damage from environmental factors, styling tools, and even simple brushing.

In contrast, other options do not accurately reflect the consequences of over-processing. For example, while curl definition may sometimes appear initially enhanced, excessive damage typically reduces curl quality over time. Similarly, enhanced moisture retention and longer-lasting curls are generally outcomes of healthy, properly processed hair, not over-processed hair, which tends to lose moisture quickly due to its damaged state. Therefore, the correct understanding of the negative impacts of an over-processed perm primarily centers around the excessive damage and breakage it can cause.
