I am not familiar with any of the products that are listed in the thread..I can tell you what I use and I have used different ones before and never even finish them because they have dried mine out.. I use products by Spectrum labs.
Spectrum Laboratories - Professional Pet Grooming Products or 800-752-3241. I use the silk system shampoo and the conditioner. Sometimes I use Miraculous Cactus conditioner..but I love their products. You can go to the website and read about them...What kind of food do you feed, that can also play a part in their skin...
