How can Crayola chalk stay in your hair?

Crayola chalk can stay in your hair due to its powdery texture, which can cling to hair strands. The chalk's pigment and binding agents can create a temporary bond with the hair, especially if it's applied when the hair is dry. Additionally, if the hair is textured or has products in it, this can enhance the chalk's adherence. However, it is typically easy to wash out with shampoo.
