What can occur if the curl formation process is weakened during perming?

If the curl formation process is weakened during perming, the result is often flat and lifeless hair. This scenario occurs because a successful perm relies on the process of breaking down and reforming the hair’s bonds through the application of chemicals and the proper use of heat and rolling techniques. When the integrity of this process is compromised—perhaps due to insufficient solution application, incorrect processing times, or inappropriate rod sizes—the hair fails to set into defined curls. Instead, the hair may end up appearing limp and devoid of volume, leading to an overall lack of vibrancy and movement.

The appearance of flat and lifeless hair contrasts with the desired result of bouncy, well-defined curls that add body and style. Other factors like frizz and shine can be influenced by different aspects of the perming treatment, but the weakening of the curl formation process specifically leads to a deficiency in curl life and definition.
