I used it and I really liked it, my hair is black and thick and it is difficult to dye it in a nice pastel color so this is great option, the only negative thing I could think of is that that chalk release dust as it dries and that could mess your clothes, Im not sure if it could be easily washed off because I realized about it right away but definitely should take that into account.
