Can I use Root Touch Up to add color to natural hair?

Root Touch Up is a temporary powder that can be used over hair that is colored or natural. It is designed to be applied on roots of the hair up to 2 inches away from then scalp and not on the lengths and ends. If using Root Touch Up on natural hair and shading out gray, using hairspray will help Root Touch Up stay on the hair for longer. Just apply the Root Touch Up and then spray lightly afterwards.
