How do I keep my hair color from fading?

I've used all different brands of hair color, been to professionals and nothing works! Bout month later my hair always seems to go back to this orangish-brown color!!! HELPHow do I keep my hair color from fading?
I have colored hair as well and I use shampoo and conditioner specially formulated for colored hair. Some I have tried and like are Bath %26amp; Body Works Signature Collection (Moisturizing) , Biolage, and C. O. Bigelow. Also, don't wash your hair frequently. If it's dirty, of course wash it, but the more often you wash it, the faster your color will fade. In addition, don't wash it for several days after you first color it. I know it sounds gross, but the color will last longer.How do I keep my hair color from fading?
