What should be monitored during the perming procedure to ensure effectiveness?

During the perming procedure, it is essential to monitor the hair's reaction to the perm solution to ensure effectiveness. This involves observing how the hair responds to the chemical changes induced by the perm solution, which includes evaluating the texture, elasticity, and overall integrity of the hair. This monitoring allows the stylist to determine whether the desired curl formation is occurring and helps to prevent over-processing, which can lead to damage such as dryness, brittleness, or excessive frizz. By staying attentive to these reactions, the stylist can make necessary adjustments, such as modifying processing time or rinsing the product out sooner to achieve optimal results. This careful observation is pivotal in achieving a successful perm that meets the client's expectations while maintaining hair health.
