Whether you're after a quick colour injection for a festival or party, or you just want to try before you buy with a bright hair colour, there's so many fun hair chalk ideas to trial. Not only are they SO MUCH FUN to play around with, but they wash right out so you can go back to your usual colour again (or, you know, try out another colour the next day if you're that way inclined). Except for pens, hair chalk comb is a more convenient and effect tool for hair chalking.http://www.jialaitefc.com/hair-chalk/hair-chalk-pen/
