What should be done prior to applying a chemical straightener?

Performing a strand test before applying a chemical straightener is crucial for several reasons. This test allows the stylist to assess how the hair reacts to the chemical treatment. It helps determine the appropriate processing time needed for the specific hair type, texture, and condition. By conducting this test, the stylist can identify potential adverse reactions or sensitivities, ensuring the safety and effectiveness of the chemical straightening process. Additionally, a strand test can provide insight into how well the hair will respond to the product, helping in making informed decisions about the usage of the straightener.

While cutting the hair for evenness, washing the hair with shampoo, or applying heat may seem relevant, they do not contribute to assessing hair compatibility with the chemical straightener. These actions do not provide the necessary information to ensure a successful application and can lead to undesirable results if the hair is not suitable for the treatment. Therefore, the strand test is essential for a safe and effective chemical straightening procedure.
