I had some gray in the front show up when it started coming in. I waited until it was a good length and then got temp (wash in) color. I didn't have a reaction...any kind of anesthesia and harsh chemicals in your body can affect the coloring process. I didn't go swimming or out in the sun for a couple days so it set really well. Been coloring now for 7 years! I too felt too young to be gray yet! My youngest was 1 1/2 when I finally had some hair coming back in.
The good part about temp color is they can fix it pretty easy.
