When performing a strand test, which color should you use?

Using the color that will be used in the service for a strand test is essential for achieving accurate results. The purpose of a strand test is to assess how the client's hair will react to the color treatment in a small section of hair before applying it to the entire head. By using the actual color intended for the service, you can evaluate the final result, including the shade, development time, and any potential reactions or outcomes that could differ based on the client's hair type, porosity, or condition.

In a strand test, the stylist aims to mimic the conditions that will be experienced during the full application. Using a color different from what will be applied—such as a contrasting, darker, or lighter shade—will not provide an accurate representation of the finished look. It is important to have a realistic preview of how the chosen color interacts with the client's hair to make informed decisions about processing time and any necessary adjustments. This approach ensures the client's expectations align with the final results, thereby enhancing client satisfaction and reducing the risk of unforeseen issues during the service.
