Chi Chromashine is Chi's professional line of fashion colours. I purchased it on a whim, having knowledge from classes while in cosmetology school. I lightened and then applied it to my hair in November 2015, and here we are at the end of January 2016 and the colour is still very vibrant with little to no fading. It smells like your typical chi product and leaves the hair feeling very soft due to Chi's use of silks instead of products like Argan oil.
