I use Isle of Dogs #10 shampoo and heavy conditioner #51, IV SanBernard PEK conditioner and Fruit of the Groomer shampoo and also Black Passion shampoo, and sometimes Chris Christensen Spectrum 10. I highly recommend the Madan combs (mustache comb--a must and grooming combs), Madan brushes, and other products from Jenny(mimimomo). She can help recommend shampoos and other grooming products, and her customer service is exceptional. She offers a 10% discount to YT members.
