Here is how to color your hair using chalk:
1. Get yourself some chalk pastels(soft pastels). Make sure they are CHALK pastels and not OIL pastels; otherwise you'll make even more of a mess!
2. Pick your favorite color of chalk, and wet the tip of the chalk you have chosen. Then rub the end of the chalk up and down the tips of your hair, re-wetting when necessary. If you have darker hair, you will want to apply more chalk. If you have lighter hair, you don't have to wet the chalk so much. 
3. Switch colors if you want. This type of hair is meant to be fun, go wild!
4. Wait for it to get dry, then you can style your hair any way you want. Once it's dry, it won't stain your clothes, so don't worry!
Have fun!
