Pastel Chalk Hair

So I'm gonna dye my hair soon and I'm doing dip dying, purple and wanted to try if dip dying would suit me, so I found a temporary way to view this. I found a link to colour your hair with chalk pastels (http://crazetexture.blogspot.com.au/2011/10/hair-chalking.html?), it easy and fast to do, though I found it tends to work better with people, who have light coloured hair. However here is how mine turned out. (My before after dip dyed hair up soon!)

Hope you Like!
