During a double-process hair color service, what is the first application called?

In a double-process hair color service, the initial step is focused on lightening the hair. This is crucial because the purpose of the first application is to remove natural pigment from the hair, allowing for a more vibrant and true-to-tone final color to be achieved in the second phase. The lightening application prepares the hair for the next step, which involves depositing color.

Understanding this process is key for achieving the desired results in hair coloring, as intermediate tones may result if the lightening phase is inadequately performed. The correct terminology emphasizes the importance of this first step, distinguishing it clearly from subsequent stages in the coloring process. This highlights the significance of lightening as a foundational aspect of a successful double-process color service.
