This is an easy way to get a splash of color in your hair, without permanent color!
It is really fun and different, you should definitely try it out! :)
The pastel may come onto your clothes, therefor wear old and dark clothes :)

Take a wisp of hair, and make it wet.
Colour the wisp with the pastel.
Do this in as much hair as wanted.
Let your hair dry.
Iron your hair with a flat iron or curling iron, to make the chalk stay in your hair.
You are good to go! :)
