I was using whitening shampoo on Vinny and I noticed his skin is really dry. I am sure it isn't just the shampoo, it is pretty cold here -40c and we have the furnace running steady. Anyway, I have a bottle of "Mrs. Stewart's Bluing" that I put in the rinse water when I bathe Vinny. Would it have the same effect as the whitening shampoo if I add a few drops of bluing to his regular moisturizing shampoo. I was even thinking of adding it to my own. Has anyone tried this, what do you think?
