What should be the first step in a hair coloring process?

The first step in a hair coloring process should be performing a strand test. This step is crucial because it helps determine how the hair will react to the hair dye, including how the color will develop and the condition of the hair after the application. By testing a small section of hair, the stylist can assess the compatibility of the hair and the dye, check for any adverse reactions, and predict the final color.

This procedure also allows for adjustments in the formulation or technique based on the individual hair characteristics, such as texture, porosity, and previous treatments. Properly conducting a strand test before full application ensures a better and more satisfying result for the client, helping prevent unexpected outcomes.
