4. To decide on the final style

The correct answer is: To assess the hair's response to the color and determine the processing time

The purpose of a strand test when coloring hair is to assess the hair's response to the color and determine the processing time. Conducting a strand test allows the stylist to see how the hair reacts to the chosen color product. This reaction can vary significantly based on factors such as the hair's texture, porosity, and previous treatments. By performing a strand test, the stylist can evaluate the final shade the hair will achieve, ensuring that the results match the client's expectations. It also provides insight into how long the color product should remain on the hair to achieve the desired outcome, which helps in preventing damage and ensuring the best possible result. The other options revolve around aspects that do not directly pertain to the main goal of a strand test. For instance, estimating the cost of service involves different factors unrelated to the color application, while selecting tools and deciding on a final style focus more on the practical application and overall look rather than the specific interactions between hair and color product.
