I have been buying number one all system products for a while. it is the best products I have found so far and even thought they are somewhat more expensive than others they are well worth it! I have two white dogs and believe me nothing works like these shampoos. this shampoo is the only shampoo I notice a difference with right away! it is very drying and must be followed up with a conditioner but my veterinarian even complimented me on my dogs hair being so soft and asked me what I was feeding her. the gel for tear stains from all system is also amazing
