Dries your hair out but also does its job [SEP] I don't think you can do much with chalk being used in your hair... in other words, this may very well be the best chalk hair-dying thing out there, but by the nature of it being chalk it comes with some setbacks. For instance, it dries your hair out quite a bit which can make brushing it difficult. But it does change the color of your hair (not drastically) so it probably works well as a highlighting option.
