So I was at Hot Topic the other day and I saw this little thing.
Review: The chalk for the most part does it's job. However it crumbles and creates a huge mess. Also it takes a lot more work putting on the chalk. In comparison to maybe a spray. I also feel like the chalk doesn't really stick to my hair. If I run my hands through my hair, I will have a lot of purple on my hands. The color lacked vibrance too.
So I rate it a 5/10. Next time I'll use a spray and use a red color.
