I have a friend who went to another salon to achieve an ""ashy"" blonde and came home green. Knowing Michael's many talents and experience as a stage artist, I was not hesitant to recommend him to correct the situation. My friend learned that Michael's new color line features a blue-based ash, which is important because he is able to create beautiful blondes without pulling green. Needless to say, he was able to achieve the beautiful cool blonde that my friend was looking for. Don't listen to the other reviews, Michael, Phoebe, and Jeannie are at the top of their craft, and their new color line worked wonders for my friend in need.
