When mixing a permanent hair color, the ratio of developer to color and the manufacturer's directions is crucial for achieving the desired results. Different hair color products are specifically formulated and require precise measurements to ensure the chemical process works effectively. The developer activates the color pigments and determines how long the color lasts, as well as how well it will penetrate the hair cuticle.

Following the manufacturer's directions is a fundamental step because these guidelines take into consideration the specific chemistry of the product being used, ensuring that the color is mixed in a way that maximizes its efficacy and minimizes the risk of hair damage.

While factors such as the timing of application, color choice, and temperature of the mixture may impact the overall coloring experience, they are secondary to the essential need for proper mixing ratios as specified by the manufacturer. Ensuring the correct formulation is the foundational step in any successful hair coloring process, setting the stage for everything else that follows.
