Can I use spray on hair dye when a straighten my naturally curly hair?

My hair is super curly (I m mixed), and when I flat iron it I can t get it wet or it will curl back up. Will using spray on hair dye cause it to curl up? I want to flat iron my hair for a concert, but also want to temporarily dye it.

Just try it on a small strand underneath and see.
