I use petsilk and love all their products. I also use 'Human' products on my girl maltese (3minute deep conditioning treatment) and I have noticed a tremendous difference in her hair but I follow it up with the leave in Petsilk conditioner. I use the petsilk conditioner on my Yorkie and some human products....but not the deep conditioning as he is only a year old and his hair is in pretty good shape. But you just can't go wrong with the Petsilk!
