I used it so many years ago to really remember, but the use of silicone is controversial.
Some people say it's wonderful, however. Perhaps the newer silicones like dimethicone might be okay, but I am going to do more research once I have the time. My favored leave in conditioners don't have them (Isle of Dogs 63, PEK conditioner only a natural silicone).
I read this about "The Stuff," which would make me stay away from it.
"
The older silicones, still used in products like “The Stuff” for dogs, formed a thicker layer over each hair and could eventually yellow or become brittle.
The newer silicones, like dimethicone, form an extremely thin layer over each hair; they basically mimic what the hair would look and feel like if it had a perfect, undamaged cuticle. Silicones are unbelievably useful in dog products – they are very benign to the skin and coat, in terms of gloss and texture they give you results like nothing else, and they stay attached to the hair even when the hair gets wet. This allows them to be used as stain- and mud-fighters. "
I have used Ice on Ice by Chris Christensen (which I new realize contains silicone), but I mostly use Isle of Dogs Coature Detangling Spray #63. All of their Coature products are wonderful. I buy the larger sizes, which make them so much more cost effective. You will need to buy a spray bottle, but this liter size at Amazon is about the same size as the 8.5 ounce size. I also use Isle of Dogs Shampoo 10 and Heavy Conditioner 51. Lastly, I love IV SanBernard Products. PEK conditioner is amazing, and you can take a small amount mixed with water in a spray bottle as a leave in for Detangling. I use Black Passion shampoo and masque and Fruit of the Groomer shampoo too. I only buy from them when they have a good sale, because they are expensive (except Fruit of the Groomer), but the big sizes last me a long time and are much more cost effective.
