Dying hair a couple shades lighter..how to care?

So I had been using John Frieda Go Blonder spray, and it lightened my hair quite a bit. I recently dyed it like one shade blonder, but if I hadn't have used that spray, it's probably about 3 or four shades lighter. Since it wasn't very dramatic, should I really be worried about caring for it any different then usual? My hair wasn't damaged at all by dying it, and I already take pretty good care of it. Should i just continue with my usual routine?
