Im like Nichole, I use a mixture. I have tried to use all dog products for a few shampoos but it left her hair dry and it matted easily.
I use a doggy shampoo for sensitive skin so that the human products wont irrate her, Neutrogena clean shampoo for residue removal, Bedhead and bath and body works shampoo and conditioner and Biosilk!
Biosilk is SO good for her hair and it smells so good, you only need a few drops.
I also use Bluing for a rinse and sometimes I use Pantene just to spice it up
Everyone talks about how good she smells, how clean she looks and how beautifully her hair flows. We haven't had a problem with dry or irritated skin, matts, or itchiness.
