Fashion tones are one of the hardest types of colors to achieve and KEEP. With most vibrant colors the hair must be lifted past a level 9 ( light blonde) for the colors to be vibrant. There are so many obstacles the colorist need to address when using fashion tones. Will the hair lift enough? Will it lift too much? Am I going to expose too much warmth? Will the hair be overprocessed? The answer to all of these questions : Maybe. Ideally before someone commits to a fashion color a test strand is the best way to go. Use atleast 3 different lighteners and see which works best. It’s best to explain to your clients that we can only do what your hair allows us to do. And that might mean your not getting that pastel purple today.
