I want to return to my gray hair. It is currently auburn how do I do this.

If you've used a permanent hair color on your hair, your hair won't return to it's natural gray color. You will need to be patient and let your hair grow out naturally. But, if you don't want to wait for your hair to grow out, I recommend going to the salon. The hairstylist will make your hair a light blonde shade and then add a blue and silver base color to achieve the gray look.
