High-lift blond colors are not designed for gray coverage. To create a very light result, formulate at a level 7 for the base color and add some highlights over the color to create a balanced blond on blond
result.
Occasionally, gray hair is so resistant that even when formulation, application, and time are correct, you will find that the coverage is not satisfactory. in such cases, presoftening becomes necessary. Presoftening is the process of treating gray or very resistant hair to allow for better penetration of color. presoftening raises the cuticle layer of the resistant hair to allow for better penetration of color. A presoftener acts like
a stain to the hair. it is applied, processed, and removed. Then the haircolor is applied.
