What must be done before applying a relaxer?

Before applying a relaxer, conducting a strand test and a thorough consultation is essential. The strand test allows the stylist to assess the hair's condition, elasticity, and texture to determine how it will respond to the relaxer. This step is crucial because it helps to identify any potential damage or reactions that the hair might have to the chemical processing. Additionally, a thorough consultation ensures that the stylist understands the client's hair history, including any previous treatments, dyes, or chemical processes. It establishes a clear communication channel regarding the client's expectations and the results they desire.

This combination of testing and consultation ensures a safer and more effective application process, minimizing the risk of unwanted results or damage to the hair. Proper preparation is key to achieving the best outcome in chemical hair treatments.
