keeping newly dyed hair color last

hi everyone!

     I've just dyed my hair for the first time, 5 days ago. I really want to keep the color i have and not have it fade out. I've been looking at my hair everyday and noticed its not as bright as it was.

I haven't washed my hair yet and I was wondering what hair color shampoo and conditioner is good to keep my color fresh! I live in toronto, so preferably something i can find easily.  Also, is there some special process like co-washing (conditioner) my hair everyday but  wash (shampoo) every other day? I usually just  wash my hair once a week (before dyed).

I use the Suave Professionals Color Care Shampoo and Conditioner on my color treated hair.  It is comparable to Biolage Color Care.  Not only is it designed to help keep your color, but both products also have UV protection in them to keep the sun from affecting the color.  Another product that is good for color is the Pantene line for Reds, Brunettes and Blondes.  They have shampoo, conditioner and styling products for every shade.  Hope this helps!
