Yes, we recommend mixing the Gray and Black colors together to get your perfect hair color. Start out with a small amount of Black, as you don't want the Black Hair Fibers to overpower the Gray. It may take a couple of times to get the color that you are looking for, but once you have it it should be easy moving forward! The best way to mix two colors together is to pour the Hair Fibers into a bowl, experiment until you find your perfect color, and then pour the mix back into the Hair Fibers bottle. Any extra Hair Fibers we recommend keeping for the next time you need to mix two colors together. Please let me know if you have any further questions!
