Are you using a high quality dye? I order #8 and use Wella Color Charm to color my unit one shade darker. I use the same tint with 10 volume developer to color the piece and 30 volume to color my own hair and never get the orange tint. Perfect match every time. Since I wear my hair 2 - 21/2" I can go about 6 weeks before recoloring my own hair and maybe every 3 monts doing the piece.
