Sydney really wanted some hair chalk for Christmas. After looking around I discovered you can get the same effects using chalk from the art store and lucky for her I had a box upstairs. I'm pretty sure I got this in the 5th grade. It even has the price tag still!!
It washes out but apparently can last up to 3-4 washes if you set it with a curling iron or straightener.
We didn't go that far :o)
