Will a flashlighting 40 kit make any hair color white??

Unfortunately, no. It will make your hair a yellow to a pale yellow shade. The Flashlighting is only the first step in the process. You have to use a toner to get the final "near white" shade. If your hair does not lighten to the palest yellow possible, though, you can't achieve the whiteness that you want.
