Delaware Cosmetology and Barbering Practice Exam

The first step in performing a chemical relaxer involves conducting a strand test. This essential procedure helps the cosmetologist determine the hair's texture, elasticity, and overall health, which are crucial factors in how the hair will react to the relaxing treatment. By taking a small sample of hair and applying the relaxer, a stylist can assess the hair's ability to withstand the chemical process and predict the outcome.

A strand test is vital because it allows for personalized adjustments to the timing and application of the relaxer, ensuring minimal damage and achieving the desired results. It provides insights into how the hair will behave during processing, which is essential for successful chemical relaxation. This proactive step prevents potential over-processing and complications during the treatment.

While other options, such as a patch test or an evaluation of hair condition, are also important in the overall process, the strand test directly relates to the initial phase of applying a chemical relaxer.
