What is the importance of strand testing before a perm?

Strand testing is a crucial step before performing a perm as it helps in evaluating how the hair reacts to the perming solution and allows a stylist to determine the appropriate processing time needed for the desired results. Each client's hair has unique characteristics, such as porosity, texture, and overall health, which affect how it will respond to the chemicals used during the perming process. By conducting a strand test, the stylist can assess the hair's capability to endure the chemical treatment, ensuring that the hair does not become over-processed or damaged. This proactive approach not only tailors the perming procedure to the individual but also enhances the safety and effectiveness of the treatment, leading to more consistent and satisfactory results.
