How can over-processing affect the perm outcome?

Over-processing refers to the application of perm solutions or relaxers beyond the recommended timing or frequency, or using too strong of a chemical, which can significantly compromise the hair's integrity. When hair is over-processed, it can become overly porous and weak, leading to undesirable outcomes such as breakage and limpness.

In the context of perms, over-processing can mean that the curls may initially appear tighter or more defined, but as the hair weakens, it lacks the necessary strength to hold the curl, causing not only a loss of elasticity but also an overall limp and lifeless appearance. This contrasts sharply with healthy, well-permed hair, which maintains its shape and vitality.

In summary, the correct choice highlights the detrimental effect of over-processing on hair health, emphasizing that it can lead to serious issues like breakage and lack of bounce, which are critical factors in achieving a successful perm outcome.
