Which of the following best describes the function of the product Relief shampoo?

The product Relief shampoo is specifically designed to provide itch relief for animals, particularly those suffering from skin irritations or allergies. It usually contains ingredients that help to soothe the skin, reduce inflammation, and alleviate discomfort associated with itching. This makes it particularly beneficial for pets dealing with conditions that cause itching, such as allergies, dermatitis, or other skin irritations.

The function of Relief shampoo is distinct and specialized; it does not primarily focus on eliminating yeast, which may be a characteristic of other medicated shampoos aimed at treating fungal infections. Moreover, it is not intended to be used as an ear wash or for cleaning teeth, as these would require different formulations and active ingredients tailored to those specific tasks. This focused formulation allows the shampoo to effectively target itch relief, making it the best choice among the options presented.
