How many degrees of decolorization exist in hair coloring?

In hair coloring, there are a total of 10 degrees of decolorization. This system of categorizing degrees is essential for professionals in the cosmetology field because it helps them understand how light or dark a hair color is and what level of lift can be achieved with a hair color product. Each degree corresponds to specific shades ranging from very dark to very light. The grades are usually identified on a scale, with darker shades classified at one end and lighter shades proceeding towards the other end.

When determining the right shade for a client or how much to lighten hair, understanding this scale allows for better communication of expectations and outcomes. This is especially crucial when dealing with clients who are looking for significant changes in hair color, such as going from dark to blonde, as it frames how much lifting power is required from the coloring process and the potential impacts it may have on hair health.
