chalk dip dye

I have recently been thinking about dip dying my hair again but I wasn't sure on what colours to do it, so when I saw this post on the Beauty Departments blog I thought it would be a good non permenant way to test which colours would look best on my hair. As you can see I put in blue, pink and purple. I'm not a fan of the blue because I think its to bright and makes my face look really washed out although I do like the pink and purple together. Chalking your hair makes it feel really really dry so I'm going to have to use a hair mask when I wash this out. It should only last until you wash it out with clarifying shampoo but as my hairs so light it might have stained it slightly. I still love the dip dye effect and I'm so tempted to dye it properly again but I am having second thoughts, what do you think, should I do it?
