I bought this chalk to use for my girls' hair. I was pretty impressed with the applicartion process because it was SO easy!! You literally comb the brush through the hair to deposit the color.
The color showed up better on my blond child's hair of course, but you could still see some of the color on my brunette child's hair too. The red, pink, and blue are the colors that show up the best. I was a little disappointed that the yellow and silver color didn't deposit well, and you could hardly see it at all (even on brown hair). But I still enjoyed this product and my girls like me to put chalk in their hair before their soccer games to show their team spirit :)
