My hair is red or blonde, can I use Hairprint?

At this time, Hairprint's Color Restorer only works for naturally black, dark brown, medium brown, and light brown hair. Hairprint should not be applied to naturally (or dyed) blonde, strawberry blonde, red, auburn, or brown hair with natural red tones.  We will continue to research developing Hairprint Color Restorer solutions for red and blonde hair, but for now we are unable to replicate the complex pigments that are found in these hair colors.
