This isn't really a how to or a tutorial as I didn't know what the outcome would be - but I thought you'd like to see what happened to my hair when I put grey dye over blue! It went a sorta silvery navy shiny stone wash blue shade... pretty cool if that's the look you're after! I never thought of putting grey over pastel shades to make those kinds of stone wash/denim hair so here's an easy way to do it yourself at home!
