I got these, because my son wanted to make his hair green. I didn’t want to use real dye, so I decided that I would use the hair chalk. There were a few issues like with the green chalk it has glitter which I didn't notice from the pictures, and to get the true color you’re looking for you have to use pretty much the whole chalk color or it doesn't come out right. They do have great colors though. Not all of them have glitter in it, but like I said I wasn’t expecting any of them to have glitter in the first place. I would recommend looking for one that doesn’t take that much for the color, unless you want something that you can use and toss out/one use kind of thing.
